How to run Java Swing GUI on embedded ARM Linux platform?

The object is:
A touch panel, running Java Swing GUI, with a 25 fps 320x320 mono JPEG image animation and other control buttons.
What I have now:
A Developing Board with: ARM926 CPU at 266MHz, 128M RAM, 64M ROM, ported with arm-linux and MiniGUI.
My plan is:
1. installing a X-window system to the platform, discarding the MiniGUI.
2. install j2re-1.3.1-RC1-linux-arm.tar.bz2 to the platform.
3. run my program developed on a PC.
My concerns are:
1. Both X and Java is resource consuming, can a 266MHz ARM CPU meet my requirement?
2. Is the X a must to run Java Swing GUI? If yes, how can I configure it to minimize the footprint, I mean, install only necessary modules.
3. Can J2RE 1.3.1, the only port for arm linux, support Swing classes?
4. Are there other options, such as CDC + PP(AGUI?), how to do it?
Thanks alot!

3. Can J2RE 1.3.1, the only port for arm linux, support Swing classes?I'm not entirely sure from your post: is this a J2SE port? If so it will support Swing, but probably needs Qt.

Loading large files in Java Swing GUI

Hello Everyone!
I am trying to load large files(more then 70 MB of xml text) in a Java Swing GUI. I tried several approaches,
1)Byte based loading whith a loop similar to
pane.setText("");
             InputStream file_reader = new BufferedInputStream(new FileInputStream
                       (file));
             int BUFFER_SIZE = 4096;
             byte[] buffer = new byte[BUFFER_SIZE];
             int bytesRead;
             String line;
             while ((bytesRead = file_reader.read(buffer, 0, BUFFER_SIZE)) != -1)
                  line = new String(buffer, 0, bytesRead);
                  pane.append(line);
             }But this is gives me unacceptable response times for large files and runs out of Java Heap memory.
2) I read in several places that I could load only small chunks of the file at a time and when the user scrolls upwards or downwards the next/previous chunk is loaded , to achieve this I am guessing extensive manipulation for the ScrollBar in the JScrollPane will be needed or adding an external JScrollBar perhaps? Can anyone provide sample code for that approach? (Putting in mind that I am writting code for an editor so I will be needing to interact via clicks and mouse wheel roatation and keyboard buttons and so on...)
If anyone can help me, post sample code or point me to useful links that deal with this issue or with writting code for editors in general I would be very grateful.
Thank you in advance.

Hi,
I'm replying to your question from another thread.
To handle large files I used the new IO libary. I'm trying to remember off the top of my head but the classes involved were the RandomAccessFile, FileChannel and MappedByteBuffer. The MappedByteBuffer was the best way for me to read and write to the file.
When opening the file I had to scan through the contents of the file using a swing worker thread and progress monitor. Whilst doing this I indexed the file into managable chunks. I also created a cache to further optimise file access.
In all it worked really well and I was suprised by the performance of the new IO libraries. I remember loading 1GB files and whilst having to wait a few seconds to perform the indexing you wouldn't know that the data for the JList was being retrieved from a file whilst the application was running.
Good Luck,
Martin.

How to run java program from website?

Hello
I'd like to know how to run java program from my web page.
I'd like to push some button in this web page so java program that would be on my server
would pop-up. Can it be done automaticaly upon running this web site? (without any buttons - I just enter website and program pops up).
Cheers

I rather thought about RMI. But I could try servlets. So how it would look like?.
I would make http request in browser (enter address) and program would show up in its window?. And I would not have to change anything in my program?. This program would run then on both boxes?. One remotely and one not?.
But I would have to learn some basics, I've never worked with servlets. Could you suggest some good sites about it?. With ready examples so I could tweak them to my purpose.

Java Embedded ARM Linux edition

I tried "Java Embedded ARM Linux edition" on "Familiar GPE 2.7".
Magically for the 1st time, I was I able to compile a java source using GPE linux on my iPAQ h2200.
Then I manually copy a few more libraries to test up in the device, "tools.jar" and "hsqldb.jar".
I tried to compile and run a simple "JOptionPane.showMessageDialog()" UI object.
I'm able to compile but failed to run it with errors below:
"java.awt.HeadlessException ... <unknown source> ..."
"... <unknown source>"Was Java Embedded meant to support swing object, or awt?
Since this is an evaluation distribution (which will expired after 90 days), how do I get a full distribution?
Thanks for any help.
By Avatar Ng

Yes I'm refering to "Embedded SE for Linux ARM evaluation binary", and I'm testing it on GPE Linux on my iPAQ h2200 device.
I got following when I typed "java -version"
I able to run and compile java in console mode, just that I didn't get my gui working ...
The last finding I have is to run with phoneme arm distribution, crossing my fingers ... wish me luck.
I should update the testing results ib my blog below should it be a fail or success.
Thanks for any help!

"scripts" are entirely different from GUI applications. What do you expect to happen when you run a Swing application through telnet on another machine? Do you expect the Swing UI to be magically transported to the local Windows machine?
Not gonna happen. Yes, like ejp hinted, you could run an X-environment on your local machine and have the Swing UI tunnel its output there, but are you sure you want GUI apps to run on a remote machine like that? It's not gonna be fun to work with, I'll tell you that.
Why not create a Java WebStart app (or perhaps even an applet) out of your application, so your users can run the application locally?

This is confused and confusing probably because my english is not my language, and because i am not sure how a Java application works.
For running JSP on my local server, it is was easy, and I did need to know how it really works. I installed Tomcat server and Java SDK.
To run my application, i jsut need to type http://localhost:8080/myPage.jsp.
That description is not exact.
The server is running Tomcat with your application.
Your browser (not the application) connects to the server (tomcat) and the server (tomcat) runs your application and returns the result to the browser.
If i want to run the same myPage.jsp on my distant server, i would need probably to install something on my server?
www.mywebsite.com/myPage.jsp will not work just like that of course.
You need to install a number of things. At a minimum Tomcat and your application (the thing that runs inside Tomcat.) There is likely to be other requirements as well such as java and patches and perhaps a database server (if your application uses a database.)
So what do i need exactly to install on my server to run a JSP?
In fact, i am afraid if i install Tomcat on my server, the other applications will not work.What "other" applications?
Is Tomcat already installed on the server? Is there already other applications running on that server? Then yes you must install your application into Tomcat (not the server) such that it will not stop the other applications (in Tomcat) from running.
