APEX Tabular Forms Deep Dive at #ORCLAPEX NYC Meetup

2014-11-10T21:57:29.127-05:00

Ever heard of APEX$ROW_NUM, APEX$ROW_SELECTOR and APEX$ROW_STATUS? Did you know you can reference tabular form columns using bind variable syntax in your page processes? Are you familiar with the execution scope of tabular form processes for modified vs submitted rows? Ever struggled using apex_application.g_fxx arrays with checkboxes? And do you really need to use the apex_item APIs? In APEX 4.0, 4.1 and 4.2 we've introduced lots of new tabular form features, including declarative tabular form validations and page processes, yet there are still PL/SQL processes being written that loop through the apex_application.g_fxx arrays or tabular form regions that mix apex_item API calls with using built-in form elements.

So when planning our next #ORCLAPEX NYC Meetup, we've figured this would be a great topic to cover. And since we don't want to talk you to death during a single meetup - we decided that we'll do a three part series, starting slow and covering the basics during our next meetup on 11/06, then dig a little deeper in part two and then conclude this series with a grand finale during the third meetup in this series.

Join us on Thurday, November 6th at the Oracle office in Manhattan, at 120 Park Ave. We're starting at 6pm and we'll serve pizza this time - thanks to everyone's generous donations last time.

RSVP today:  #ORCLAPEX NYC Meetup

Developing Mobile Web Applications with Oracle Application Express 4.2

2014-01-17T16:33:23.648-05:00

If you’re interested in developing Mobile Web Apps on the Oracle Database – and if you’re following my Blog, chances are that you are – then here’s a great opportunity to get up to speed on the latest trends and learn how you can quickly and easily develop your own mobile web apps and extend your existing APEX apps for mobile use: attend my upcoming free ODTUG Webinar on February 20th:


Here’s what I will be covering: 

Smartphones and tablets are now commonly used throughout the enterprise. Thanks to easy to use mobile apps, ready access to the Internet, and widespread use of web- and cloud-based applications, mobile devices are a logical choice for many employees. Businesses need to respond to these trends by modernizing their public facing websites for mobile use and providing employees with access to in-house applications that support a variety of different devices and screen sizes. Solely building for desktop use and standardizing on IE only won’t cut it anymore. 



Oracle Application Express (APEX) provides you with powerful tools to quickly and efficiently build mobile web apps and to easily extend your existing desktop applications for mobile use. Regardless of whether these applications were built with APEX originally or use other technologies—as long as they’re running on top of an Oracle Database, APEX will enable you to quickly build mobile apps that provide access to your data and interact with your business processes. 



During this session, we’ll discuss mobile development trends and responsive web design, walk you through the basics of the jQuery Mobile framework, and provide you with an overview of the mobile development capabilities built into the current release of Oracle Application Express 4.2. We will include several live demos to get you started, so have your phone or tablet ready to try out our sample apps live while they are being built.

White Paper on Custom PDF Reports in APEX

2013-05-30T12:43:44.908-04:00

As I’ve previously blogged about and outlined in my video tutorials, it is now possible to create custom PDF reports with APEX 4.2.2 using the APEX Listener 2.0.2 and third-party tools like Altova Stylevision or Stylus Studio. To help our customers getting started with this, we’ve just released a white paper that outlines the system requirements, explains the configuration steps and options and then walks you through the creation of PDF reports using custom layouts step by step. The white paper is available on out Oracle Application Express OTN page:http://www.oracle.com/technetwork/developer-tools/apex/application-express/apex-white-papers-1866964.html[...]



PDF Reports with APEX at NYOUG

2013-05-23T17:25:29.601-04:00

The New York Oracle User Group Summer Meeting takes place on June 5th at St. John's University, right next to the World Trade Center in Downtown Manhattan. This looks like it’s going to be a very interesting meeting for Oracle DBAs and Oracle Developers. There are two session scheduled covering the Oracle Database 12c and also two APEX sessions. There’s going to be a session on building mobile apps with APEX, which looks to be very hands-on. And I’ll be showing how to build custom PDF reports with APEX. I’ll walk you step by step through creating the report in APEX, downloading the XML, creating a report layout with tools like Stylevision, loading the layout back into APEX and associating the layout with your report. If you have a laptop running APEX 4.2.2 and the APEX Listener 2.0.2, you’re welcome to bring it and follow along – you will need at least a trial version of either Altova Stylevision or Stylus Studio.Details about this event can be found on the NYOUG website:http://nyoug.org/upcoming_events.htm#General_Meeting[...]

PDF Printing with Oracle Application Express 4.2.2

2013-04-26T17:58:31.155-04:00

Oracle Application Express 4.2.2 was released today, you can download the full release from the Download page on OTN. As always, there have been numerous improvements and bug fixes. We’ve updated many of our included packaged applications and we’ve introduced a new packaged application: the Survey Builder, which you can use to easily create and run surveys.With APEX 4.2.2 and the APEX Listener 2.0 we’re also introducing a number of report printing enhancements. Using the APEX Listener for PDF printing has been added as a third option in addition to using Apache FOP or Oracle BI Publisher as external print rendering engine. The main difference in using the APEX Listener for PDF printing is that the FOP libraries are actually built into the Lister, thus no complicated configuration of an external engine is required in this setup. All that’s required is to log into the APEX Instance Administration, select the APEX Listener as the Print Server, and then enable PDF printing for your Classic Reports, Interactive Reports or Report Queries. And unless you’re calling the APEX Print APIs directly in your custom PL/SQL code, you also won’t have to enable networking services in the Oracle database anymore, because the APEX Listener based printing option loads your reports straight to the APEX Listener, which then renders them in PDF format and downloads them to your browser.To help you get started with using the APEX Listener for PDF Printing I’ve created a short video that walks you through the configuration steps in the APEX Instance Administration and then shows you how to create a simple report with PDF export enabled: allowfullscreen="" frameborder="0" height="315" src="http://www.youtube.com/embed/1PiI-D0JmNY" width="560"> We’ve also improved support for custom XSL-FO layouts in APEX 4.2.2. This means, you can now more easily customize your PDF reports to your requirements using third-party tools like Altova Stylevision or Stylus Studio that allow for drag and drop layout of XSLT stylesheets. So if you have a Report Query or Classic Report Region, you can now simply download your report data in XML format and use this XML data as the data source for any of these tools. Once loaded into the tool, all components of your report data, including information about your application, page, report region, user name as well as session state can be easily included in the layout via drag and drop. Once you completed your layout, you can safe it as a XSLT 1.0 file and upload this file into APEX as a report layout (under Shared Components). Now you can update your report query or classic report region to use this custom layout when exporting your report in PDF format.I’ve created a second video, which walks your through all the details. Starting with the sample app created in the first video, I’m showing you how to export your report in XML format, load this XML file into Altova Stylevision or Stylus Studio, then I'm demonstrating how to use these tools to create custom layouts and finally how to upload your completed layouts and use them for your reports in APEX: allowfullscreen="" frameborder="0" height="315" src="http://www.youtube.com/embed/UVasaddrZI4" width="560"> [...]

Kscope '12 and the Rodeo Special Event

2012-06-30T22:11:48.163-04:00


Just arrived back home in New York after a great week at the ODTUG Kscope ’12 conference in San Antonio, TX. It was great meeting many members of our ever growing APEX community again, seeing several outstanding presentations on APEX and other topics and being able to present to our customers what’s new in Oracle Application Express 4.2 and introducing the mobile features we’ve been working on over the past couple of month.

If you've been to our sessions and want to try out for yourself what's new, or if you're just curious what APEX is all about, please sign up for our Early Adopters hosted site at:

https://apexea.oracle.com 

And thank you Kscope for organizing yet another amazing special event Wednesday night, I truly enjoyed the Rodeo, certainly something you don’t see every day in New York City. I’ve put together a few scenes of the event and loaded the up on YouTube, please check out the video here:

Application Express 4.2 Early Adopter and Kscope 12

2012-06-21T23:17:39.038-04:00


Today we released the first Early Adopter version of Oracle Application Express 4.2 – right in time for ODTUG KScope12. You can sign up and give it a try:


One of our focus areas in this release of course has been Mobile. And while we’re still actively developing many of the new features in APEX 4.2, you’ll find that you can already build pretty nice looking and usable mobile applications.

With KScope starting this weekend, I thought what better way to illustrate some of the capabilities in APEX 4.2, than to publish a very simple KScope scheduler, highlighting the sessions that are going to be presented by members of the Oracle Application Express development team:


I recommend opening this link on your mobile phone. And if you’re reading my Blog on your desktop (people still use those?), then here’s a handy QR code to save you the hassle of typing in the URL:
I list all the sessions with a simple search box and you can also drill down by presenter, or day. And if you feel like letting us know that you’ll be attending some of these sessions, feel free to leave you name and email for your session(s) of choice.

And lastly, you may have noticed I felt a bit inspired by the conference location, and colorized my app accordingly. If you’re building you apps with the APEX 4.2 EA, you’ll find you currently only have a choice of blue with different shades of gray. But jQuery Mobile offers very easy ways to customize your look & feel to your or your users’ taste. So if you want to learn more about that, and want to see mobile development in APEX 4.2 in action, stop by my session on Wednesday at 9:45am:







Dynamic Images in PDF - What 32k Limit?

2012-02-23T15:56:26.212-05:00

Looks like it's time to follow up on a Blog posting I wrote in 2008 about including dynamic images in PDF reports. After being called out on that good old 32k limit in a recent Blog posting by Roel Hartman, and reading through the recent OTN Forum posts and tweets on that topic, it would be rude not to respond ;-)While I did state that we were looking to lift this 32k limit, this has not yet made it in, i.e. the limit is still in place. However in my posting I was also saying that if the XML data is generated by some other way, and the PDF rendering is done using the print API, then the use of larger images would be possible. And that is certainly the case, so let's take a look at how this could be done.The key piece is our Print API (apex_util.download_print_document and apex_util.get_print_document), with this API you can generate PDF and other documents through a simple PL/SQL API call. This API is taking care of all the communication with BI Publisher or FOP for you. The apex_util.get_print_document API can be called to generate and retrieve the print document as a BLOB in the database for further processing, like storing the document in tables, etc. The apex_util.download_print_document API can be called in an APEX page process to generate and download the print document straight to your client. Both APIs have three different signatures, they allow for programmatically downloading report queries while dynamically associating stored report layouts at runtime, downloading report queries with custom templates stored in your own tables, and generating PDF based on your own custom XML using your own custom templates.This last scenario is what we want to use for our dynamic images sample, i.e. we're going to generate the report data in XML format ourselves, thus getting around that 32k limit and store the report data in a CLOB. We're then also going to store our report layouts in our own tables, and query them up dynamically at runtime. The API for this looks as follows (for further details, reference the Oracle Application Express API Reference):-- -----------------------------------------------------------------------------------------------procedure download_print_document (---- This procedure initiates the download of a print document using XML based report data and RTF or XSL-FO based report layout.---- Arguments:-- p_file_name Defines the filename of the print document-- p_content_disposition: Specifies whether to download the print document or display inline ("attachment", "inline")-- p_report_data: XML based report data-- p_report_layout: Report layout in XSL-FO or RTF format-- p_report_layout_type: Defines the report layout type, that is "xsl-fo" or "rtf"-- p_document_format: Defines the document format, that is "pdf", "rtf", "xls", "htm", or "xml"-- p_print_server: URL of of the print server. If not specified, the print server will be derived from preferences-- example: http://myserver.mydomain.com:8888/xmlpserver/convert-- p_file_name in varchar, p_content_disposition in varchar default 'attachment', p_report_data in clob, p_report_layout in clob, p_report_layout_type in varchar2 default 'xsl-fo', p_document_format in varchar2 default 'pdf', p_print_server in varchar2 default null);Now of course the question is, how do we get our data into XML format, if we don't have APEX take care of that for us, and where do we get the images from and how to we include them in this API call? Getting our data into XML format is the easy part, let's say you wa[...]



Mobile APEX Apps – Next Steps

2012-02-06T16:41:24.818-05:00

It's been a few weeks since my last Blog posting on mobile development, or any topic for that matter. I've been busy doing Cloud development and talking about it at UKOUG and NYOUG. Then there's the ongoing work on APEX 4.1.1, which actually won't ship with jQuery Mobile bundled in, mainly due to jQuery Mobile's minimum requirement of jQuery 1.6.4 while APEX 4.1 includes jQuery 1.6.2, and a patch release won't be the right time to move that up. But as my previous mobile samples and especially the mobile version of the Oracle Learning Library show, it's certainly possible to use jQuery Mobile in APEX 4.1 today. So the full integration of jQuery Mobile with APEX, incl. declarative / wizard-driven support for building mobile web applications is currently planned for APEX 4.2, which actually was the subject of some recent meetings in Vienna, Austria.While we wait for (and work on) APEX 4.2, I'm planning to continue blogging about what can be done with jQuery Mobile and APEX today, publish some ideas and gather feedback from our users on what they'd like to see in terms of mobile support in APEX 4.2. And one area that I found increasingly cumbersome in my mobile development efforts was to quickly try out my latest mobile creations on my iPhone and iPad. I kept sending emails to myself with the URL to my mobile APEX apps, bookmarked those URLs, but then ended up constantly creating new apps, requiring new boomarks. I also tried to just cloud-sync my bookmarks between my MacBook and mobile devices, but that wasn't ideal either.Then I thought if I have these difficulties while developing, end users might have similar issues. For example, some of our new Cloud-based productivity applications will have a link that takes the user to the mobile version of a page or app. And that's great if they're already on a mobile device, but what if for example, a users sits at his desks, runs some analysis, and then needs to run to a meeting and he wants to take the results with him on his mobile device? Well, one possibility would be to just display a QR code on the desktop version of his report, and then allow him to scan that QR Code with his mobile device, which would then take him straight to the mobile version of that report. Sounds like a good idea? Here's how this could look like, just open the following page on your desktop or laptop:http://apex.oracle.com/pls/apex/f?p=49611:1It's a very simple Interactive Report on the EMP table, and right next to it, in the sidebar, I show a QR code, which can be scanned with one of the many bar-code readers available for smartphones, like RedLaser.Once scanned, you will typically be prompted by your smartphone whether you want to go to the URL, and if you proceed, your mobile browser opens and takes you to this page:http://apex.oracle.com/pls/apex/f?p=49611:10To generate the QR Code I wrote a very simple QR Code Generator APEX Region Plug-In that takes in the text your want to encode, and the width and height of the QR Code image and then calls out to Google to have the actual image generated.If you would like to take a look at the app, see how it's done and use some ideas for your own apps, you can download the application here:Download Mobile QR Code Demo[...]



Getting Started with Mobile in APEX - Part 2

2011-11-17T17:41:28.663-05:00

jQuery Mobile 1.0 Final was released today! Time to take it for a spin. As outlined in my previous post, jQuery Mobile is available for download on the jquerymobile.com web site:

Alternatively, if you were referencing the CDN, you could of course also simply update your jQuery Mobile enabled templates and remove the "RC2" or "RC3" suffix from your file references:




Then just re-run your pages, and you'll be up and running using the shiny, new final release of jQuery Mobile 1.0!

Now running my original "Hello World!" sample with jQuery Mobile 1.0 would be a bit boring. So here's a new sample application, this one should be more interesting. It's a very basic message board application. Point your mobile device (or desktop browser) to this URL:

You'll get a home page showing recent messages, along with the title, author and create date and time. When you click on a message, you'll get to a read-only view of the message details. When you click on the create button on the home page, you can enter a new message, with your name, email and message title. Give it a try, leave me some feedback and comments, and if you like the app, it's available for download as well. It comes with the underlying database objects bundled in as supporting objects, i.e. they're created when you install the application.

For the most part, this is a standard APEX application, nothing too fancy or out of the ordinary. The only relevant templates are those containing "mobile" in their names. The home page was built as a standard classic report page, using a customized named-column report template. The form page is a standard APEX form, which is omitting the form table-grid using the corresponding region template attribute and using the new label template field container attributes. The buttons use simple anchor tags, and illustrate how you can have different button colors, using the new "hot" attribute for buttons. And for the back button, I used a jQuery Mobile button icon, which can be easily included using the HTML data- attributes, data-icon in this case.

So try out the application, and leave your comments in the message board. I'll follow up with additional details on some of the more advanced concepts in upcoming posts.




Getting Started with Mobile in APEX - Part 1

2011-11-15T13:46:30.926-05:00

With jQuery Mobile moving closer to production, I finally started working on my paper documenting how to develop mobile applications with APEX 4.1 We've put a lot of changes into APEX 4.1 that make the integration of frameworks like jQuery Mobile easier. Full mobile support, with mobile templates and components that are optimized for mobile devices, is currently planned for APEX 4.2. But that doesn't mean that you couldn't start building mobile apps with APEX today. It'll just be a bit more manual work for now. So while working on the paper, I've figured I'll start blogging about this as well, taking you step by step through the process of enabling mobile development in APEX 4.1, integrating the jQuery Mobile library and building your first mobile app.So let's get started. The first thing you'll need to do is set a system preference in APEX that enables mobile development, to do this, logon as SYS and run the following:exec apex_040100.wwv_flow_platform.set_preference('MOBILE_DEVELOPMENT_ENABLED','Y') ;Don't worry, this will have no effect on any of your existing applications. What this system preference does is that in a number of places in APEX, you'll now see a select list that lets you choose between a "Desktop" and "Mobile" mode. The most important place where that's relevant is when editing a page template, i.e. you can now define that page template to be a mobile page template or a full-size / desktop page template. Once we have jQuery Mobile fully integrated, currently targeted for APEX 4.2, this will trigger the inclusion of the jQuery Mobile library, and the omission of some JavaScript and CSS references that are not needed for mobile. For the time being though, all this is doing is that it makes APEX render form elements on your mobile pages without a table grid. This gives you better control over the HTML generated by APEX, which allows the generation of HTML code that follows to jQuery Mobile syntax. Having a mobile page template in your current theme also triggers the mobile option in the create page wizards. So you can choose to build a mobile page, which hides page types from the wizard that don't yet work well on mobile, like e.g. Flash charts. And as you step through the wizard, the wizard will pick up your default mobile templates, instead of the standard templates, but only if you have actually set your mobile defaults for your theme.Next you'll need to install or reference the jQuery Mobile libraries. These libraries are not yet bundled into APEX because jQuery Mobile is not yet production software. However you can download the libraries directly from jquerymobile.com or even easier, reference the CDN-hosted libraries in your page template. To reference the CDN, simply include the following in your page template:If you prefer downloading and installing jQuery Mobile in your APEX instance, go to this URL and download the ZIP File from there:http://jquerymobile.com/download/Then extract the contents of this ZIP file and load them into your APEX images directory. When using the APEX Listener or Apache/mod_plsql, you can simply copy the files to the images directory. When using the Embedded Gateway, you will need to connect to your database via WebDAV or FTP and upload the files into XML DB. To fo[...]

Oracle APEX 4.0 Cookbook

2011-03-01T17:42:08.810-05:00

Thanks to some recent train travel, I had a chance to catch up on some reading, and so I looked at the recently published Oracle APEX 4.0 Cookbook by Michel van Zoest and Marcel van der Plas. It's great to see more and more APEX books coming out, and of course there are already several excellent ones out there. This new one I found quite interesting due to the way it's been structured. The authors basically have chapters covering the main areas of interest, i.e. creating basic applications, themes, websheets, web serivces, APIs, etc. And then within each chapter, they have smaller sections that lay out, step by step, how to go about e.g. creating a form, creating a report, creating a theme, etc, all broken down into very manageable pieces. And in each section, they tell you what you need to get started, then walk you through the steps, and then provide some background info on how it all works. So I think this is the kind of book an APEX developer might put on his desk (or e-reader) to quickly look up specific features while they are developing their applications. I think this book provides a great value to both experienced APEX developers and developers who just recently got started. It's not necessarily targeted towards complete beginners though, i.e. it's not so much an introduction into APEX as the authors pretty quickly get into more advanced features, like APIs, AJAX, JavaScript, etc. So for anyone looking for an APEX book they can use to quickly look up certain features, and how to use them, this book is doing an excellent job.




8th Annual NYC Metro Oracle Users Group Day

2010-12-07T11:29:02.814-05:00

If you're in the NYC metro area tomorrow, come join me at the 8th Annual NYC Metro Oracle Users Group Day. The day kicks off with Andy Mendelsohn's keynote on Oracle 11g. Andy Mendelsohn is Oracle's Senior Vice President of Database Server Technologies, and our team, the Oracle Application Express group, is part of that organization.

And a little bit later, at 11:45am I'm on with my presentation about the architecture and configuration options of Oracle Application Express. I'm planing to dig a little bit deeper than usual into how APEX actually works, and walk you through the different setup options with the APEX Listener, Embedded PL/SQL gateway etc and review the install and update process. I presented several different APEX topics at a number of recent NYOUG meetings, and in addition to questions about these feature, I also always get a lot of architecture and configuration related questions, so I thought this time, I''ll dedicate my whole session to this.

You can find more information about the event here:

culture shock ;-)

2010-11-19T16:33:59.258-05:00

This week's DOAG 2010 conference in Nuremberg finally gave me an opportunity again to visit Germany after not having been there in a few years, and to present to a very engaged local APEX community in my native tongue. I think the conference was a great success and I was excited to see how many APEX sessions were scheduled this week - and it seems all the APEX sessions drew large audiences. I think Patrick Wolfs's and my sessions had about a hundred participants, close to capacity of the rooms. And Carsten Czarski had managed to hook us up with an additional session in the Demo Kino, so I ended up speaking for about three hours straight on Tuesday. I had a few customers come up to my podium after my presentations, thanking me for the information on APEX 4 and my demos and after they had seen on the schedule that I'm from New York, congratulating me on my excellent German skills. Of course they were less impressed, after I revealed to them that I had actually grown up in Germany.I also really enjoyed the DOAG party Wednesday night. I was having dinner with Todd Trichler, Kuassi Mensah and Tom Kyte. The event organizers had setup a great buffet, live music and very neatly arranged tables. And each table had very attentive waitresses, who took good care of us. A few minutes into the dinner Bryn Llewellyn stopped by, and someone in my group suggested we could move a little and Bryn could pull over a chair from a neighboring table - which he promptly did. You should have seen the look on the face of one of our waitresses, she appeared to be in complete shock and disbelieve that someone would dare break the order of the tables and chairs. And just as I was making a joke to Todd, explaining some of the cultural differences, Steven Feuerstein stopped by, grabbed a chair from a neighboring table as well and unfortunately for him, took a chair from the VIP table were Oracle Germany's top management was having dinner. That of course was too much for the poor waitress, who promptly moved the chair back into it's proper position. Thankfully one of the DOAG officials became aware of the situation and personally setup a chair, plates and silverware for Steven on our table and we got to enjoy the rest of our dinner.
