Java Technology, Java ME (J2ME) Technology, and the Wonderful Wireless World

Sometimes you want to use quicker GCF vs. java.net in OJEC 1.1 (Java ME CDC)

Fri, 10 Feb 2012 20:25:04 +0000

There are times that Java ME specific Generic Connection Framework (GCF) programming is quicker than Java SE style java.net.* programming. For example, when there's need for an HTTP connection, using the GCF HttpConnection in Java ME CDC (now called OJEC 1.1) was sometimes more convenient on a Java ME device.

Source code sample:


     import java.io.*;
     import java.net.*;
     import javax.microedition.io.*;

     HttpConnection c;
     InputStream is;
     BufferedInputStream bis;
     final static int    MAX_BUFFER = 204800;    // 200 KB buffer size

     try {

          String url = new String("http://oracle.com");
          
          System.out.println("Attempting to connect to: "+url);
          c = (HttpConnection)Connector.open(url);
          is = c.openInputStream();
          bis = new BufferedInputStream(is);

          // Initialize loop variables
          int index = 0;
          int numBytes = 0;
          byte buffer[] = new byte[MAX_BUFFER];

          // Loop: read to end of document
          while (numBytes != -1) {
            numBytes = bis.read(buffer, index, MAX_BUFFER-index);
            if (numBytes > 0) {
                String newStr = new String(buffer, 0, numBytes);
                System.out.println(index+": "+newStr);
                index += numBytes;
            }
          }

          // Close everything
          bis.close();
          is.close();
          c.close();
        } catch (IOException ioe) {
          // Handle the exception.
            ioe.printStackTrace();
        }

That's one of the differences from the past between Java ME technology and Java SE technology, which were two distinct legacy platforms that you could base Java technology on. Now moving to one combined Java EC governance model in the JCP will make it easier to take advantages of the combined Java ME and Java SE APIs and single Java language moving forward.




One Executive Committee to Oversee Java Technology

Wed, 8 Feb 2012 02:13:32 +0000

Here's a good article on the upcoming changes to the Java Community Process (JCP) to consolidate into on Executive Committee (EC) to oversee all of Java (Java SE and Java ME technologies).

See:

One EC to Oversee Them All

Here's a quote:

 Looking forward, the expected 
 convergence between Java ME and 
 Java SE is likely to render the 
 current division into two separate 
 ECs increasingly irrelevant. Since 
 Java is One Platform, it ought to 
 be overseen by a single Executive 
 Committee
Nice! Now that's streamlining.




Raspberry Pi with Java, a great combo

Tue, 24 Jan 2012 01:53:51 +0000

Here's a cool new embedded $35 Linux/ARM computer called the Raspberry Pi. Now, what's better with Raspberry Pi than Java? Java ME CDC that is, downloaded when you get the OJEC 1.1 Linux/ARM binary free from: here and have it with your Raspberry Pi.

See:

http://www.engadget.com/2012/01/11/raspberry-pi-begins-production/

Here's a quote:

 [T]he Raspberry Pi Model B has 
 officially begun production. Unlike 
 the Model A, this $35 computer 
 board features both an Ethernet 
 adapter and 256MB of RAM (rather 
 than 128MB).
A delicious combo!




Everyone taking potshots at Android, pointing out Java ME tech's awesome awesomeness

Tue, 17 Jan 2012 18:38:12 +0000

Now, you know there must be some type of bandwagon that tech bloggers are jumping on, if this is the third article pointing out that Java ME technology has overtaken Android. I don't even know who this guy is... but I like how he thinks! (image)

See:

Ronald O Carlson points out Java ME is awesome

Here's a quote:

 Emblematic of Android users’ gosh 
 darned pathetic stats is the fact 
 that for the second month in a row 
 devices running Java ME — the dumb 
 phone operating system — generate 
 more web traffic.
Maybe the "dumb phone operating system" isn't that dumb after all... Ya think?




Second position in mobile OS? Not Android!

Thu, 12 Jan 2012 18:37:21 +0000

Here's an article about how "Java ME enjoys the second position in mobile OS, not Android". Hey, I've been pointing that out all this time...
 Damn it feels good to be a gangsta
 I mean one that you don't really know
 Ridin' around town in a drop-top Benz
 Hittin' switches on my Java ME feature phone

See:

Damn it feels good to be a gangsta

Here's a quote:

 Google’s Android, which spread 
 like wildfire last year has been 
 losing its fizz, while the surprise 
 is Oracle’s Java ME, which is 
 emerging as the world’s fastest 
 growing mobile operating system...
And, for the haters who say the survey data is flawed, why does the trend over time show Java ME is growing and Android is declining. Trends don't lie, even if the data is focused only on mobile browsing, not units shipped. The relative trend line is showing that Android is "losing its fizz" (a quote from the article, not me) (image)




Happy 2012! Java ME growth accelerates past Android

Sun, 1 Jan 2012 13:40:48 +0000

Happy New Year everyone! As a trend into 2012 we see from the latest Net Applications Mobile/Tablet Top Operating System Share Trend for December, 2011 that Java ME technology not only overtook Android to claim 2nd place in November, 2011, but is also now accelerating past it into 2012!

See:

Java ME accelerating into 2012

It's going to be a great 2012! (Unless you're an Android fan, that is. (image) )




Net Applications Analytics from Nov 2011: Java ME moves into #2 spot

Fri, 23 Dec 2011 18:33:15 +0000

In a stunning turnaround, Net Applications reports in its November, 2011 analytics report that Android operating system market share dropped from 19% to 17% giving Java ME technology the number 2 spot with 20% of the mobile market for November, 2011. Oorah!

See:

Oorah! Semper Java ME!

Here's a quote:

 IOS slid more than seven points 
 to drop to a 54% share in 
 November, and Android shed two 
 points to fall to 17%. Android 
 also slipped out of the No. 2 
 spot it claimed from Java ME in 
 October as the feature phone 
 platform jumped seven points 
 to a 20% share last month.
Nice trend! Merry Christmas, everyone! Happy New Year too!




Mobile Trends for 2012: Majority of US phones still use Java ME tech

Tue, 13 Dec 2011 18:54:29 +0000

Well, it's official. The majority of cell phones still uses Java ME technology in the U.S. (according to the comScore numbers going into 2012). Don't believe the hype that tries to say otherwise. The media loves to lie distort the truth about smartphone adoption vs. the stronger feature phone market.

See:

Majority still on Java ME

Here's a quote:

 Apps On All Platforms

 Hildahl has a vested interest 
 in promoting the importance of 
 cross platform apps, but it's 
 hard to argue with the need to 
 be on all platforms, including 
 the mobile web and oft 
 neglected platforms like 
 Symbian and J2ME.
Wise words! Let's soak that in: There's a need to be on all platforms including the "oft neglected" Java ME platform. Heed the statistics from comScore! Program to Java ME.

Send SMS text messages for FREE using Java ME

Tue, 22 Nov 2011 19:40:07 +0000

Here's a way to get around those nasty SMS text messages charges (and maybe a way to get around the Pakistan SMS text censors too!). Use this Java ME SMS text app for your Java ME mobile phone, called JaxtrSMS:

See:

JaxtrSMS free Java ME SMS

Here's a quote:

 JaxtrSMS lets you send FREE SMS 
 and txt messages to any mobile 
 phone in the world. Best of all, 
 the receiver does not have to 
 have the JaxtrSMS app. International 
 and local SMS/texting can be 
 expensive but with JaxtrSMS you 
 can text anyone in the world for 
 FREE!
Great! Now, you can send 2,000 text messages from your phone every month and not worry about a huge bill. You don't send 2,000 text message in a month? Well, get it for your teenage kids then. They certainly send 2,000 text messages in a month...

Cool, now we can all talk and command our Java ME phones like they talk to the ship's computer on Star Trek. "Computer? Computer?"




Fake Call App: Funny app for your Java ME phone

Fri, 4 Nov 2011 19:23:31 +0000

This app is too funny! Use it to schedule a call to yourself to make your Java ME mobile phone suddenly ring, which allows you to then make up some lame excuse why you have to leave.

See:

Fake Call Java ME App

Here's a quote:

 Fake Call app - Are you at a 
 loss how to back out of a bad 
 date or any other boring 
 gathering? Use the Fake Call 
 [Java ME] application. Set the 
 time that you want your phone 
 to ring without anyone really 
 calling you. All that you have 
 to do then is to explain who 
 has called you and why you 
 have to leave.
Maybe the Fake Cosmonauts who Fake Landed on Mars could have used this when they were on their Fake Mission to Fake Call back to Earth. (image)

 wheel of his Dodge Challenger, 
 is involved in a relentless 
 manhunt throughout the City by 
 the Bay.
Yeah. OK. Where are the zombies? There's gotsa be zombies...




Kik comes back to BlackBerry with a kick - Java ME technology

Fri, 28 Oct 2011 14:55:42 +0000

Kik got booted off the BlackBerry island by RIM for allowing BlackBerry users to bypass the RIM chat app on their official platform. But, through the powers of Java ME technology, Kik is back on BlackBerries (and other Java ME devices) to allow for the freedom of chat for all mobile platforms. Show me what democracy looks like: This is what democracy looks like!

See:

Kik comes back

Here's a quote:

 RIM may not like Kik Messenger 
 or want you to use it on "their" 
 platform. Their removal, ban, 
 and subsequent lawsuit against 
 the popular cross-platform 
 chatting app made that readily 
 apparent... But by refocusing 
 their efforts on a completely 
 re-written from scratch Java ME 
 app, Kik has re-entered 
 BlackBerry users’ world.
You can free your mobile app also, from the bonds of Corporate Servitude. Just use Java ME to Occupy any Mobile Device.




Modernizing Java ME technology, with an "s" instead of a "z"

Wed, 26 Oct 2011 18:35:50 +0000

Here's an article from the UK that talks about how Oracle "modernises" (no time to spell it with a "z", so use an "s" instead like they do in Great Britain) the Java ME Platform.

See:

Modernising Java ME

Here's a quote:

 Adam Messinger, Vice President of 
 Development on Oracle Fusion 
 Middleware, said in a statement, 
 "We are very excited about the 
 future of Java ME, which will 
 further extend the world’s 
 leading application platform for 
 mobile and edge devices and offer 
 increased opportunity for both 
 Java developers and mobile 
 operators."
Well, however you spell "modernises", it's a fact that Java ME technology keeps getting better every year. Tomato, tomahto. Potato, potahto.

See:

RapidProtect: Java ME app

Here's a quote:

 In a rapidly changing security 
 environment with all kinds of 
 natural and manmade threats around 
 us, the well being of family 
 members is a major concern for 
 all of us... Rapidsoft Systems

 Zlango has delivered over 8 billion 
 icons globally across multiple 
 platforms ([Blah-blah-blah], J2ME, 
 Web, ICQ integration) and on over 
 500 supported types of mobile 
 phones.
Scary. There's nothing like Java ME Zombie icon text messages to scare the beejeebers out of everyone. Braaaaaains...

Canon and Oracle sitting in a tree, p-a-r-t-n-e-r-i-n-g on Java ME tech

Mon, 26 Sep 2011 18:42:36 +0000

Canon and Oracle have announced a match made in heaven: Canon for document processing, and Oracle for... heck, everything else! Including Java ME technology.

See:

Canon and Oracle partner on Java ME

Here's a quote:

 In the future, the company said it 
 will work with Oracle in developing 
 middleware for its online storage 
 service, and the two companies will 
 also work together to further develop 
 and refine the Java programming 
 language.

 Canon has long used Oracle's Java as 
 the basis for a third-party 
 application development platform with 
 its multifunction copiers, and the 
 new joint development will extend 
 that partnership...
Java software and databases in office copier and printer equipment? Great match! It's as easy as being shot out of a cannon.




When you bling a phone, make sure it's a Java ME phone

Fri, 23 Sep 2011 20:00:20 +0000

Dog's got it goin' on! My homies over at JSC Ancort and the world famous Austrian jeweler, Peter (Snoop Dog Tupac Biggie Smalls) Aloisson, blinged-out a Java ME cell phone with enough bling bling to make Paris Hilton blush. We're talkin' 1,300 G's, G! That's livin' large, the Java ME technology way.

See:

Java ME Bling

Here's a quote:

 The handset also has an MP3 player, 
 a Microsoft Word document viewer, 
 video calls, email, web browsing, 
 JAVA support and 4000 contacts can

Java Summer Workshop 2011

Wed, 7 Sep 2011 20:05:42 +0000

width="360" height="222" src="http://www.youtube.com/embed/h0fw7KpTR9g" frameborder="0" allowfullscreen> On August 10-12, 2011, local high school students and teachers as well as Oracle employee sons and daughters attended an onsite introductory Java programming workshop, where kids learned about Project Greenfoot and Project Alice, two cool ways for children to learn Java programming.

See:

Kids learn Java

Watch the video and see some sharp kids who are enthusiastic about Java technology. That's cool! Where did they get all these clever children from? I expect each one to grow up to be a Mark Zuckerberg or Carol Bartz... er, uh... wait, not Carol Bartz. I mean, um... Marissa Mayer. Yeah, each kid will grow up to be a Mark or Marissa. (image)
