Creating a gui with j2me

Hi, I'm making a midlet, and I want to create a gui. i think the best way for making this is using canvas, but I can't find any tutorial/example. The gui would be something like this:
http://bladecoder.net/hof/images/sf1.png
ah, and I cannot use j2mepolish.
Thanks for your help.

Please start with the link mentioned above. After discovering the APIs you need you can find numerous examples of custom UIs.
A couple of years ago there was a great example of creating a a custom UI framework on the web. I cant seem to find it now. The closest thing I could find now is http://www2.sys-con.com/itsg/virtualcd/Java/archives/0606/cordrey/index.html
Visit the Nokia and SE developer site. SE, especially, always has good examples.
I use the low level API for all my J2ME work. As an aside, you can look at some of my "weekend" projects. Here are some screenshots.

Grab the source if you like, but learn the basics first. I would not want you to inadvertently pick up any of my "bad habits." If you have time to waste, and dont mind lax production:), you can watch video demo an custom ui here:

Creating a little GUI with adding DNS record functionality

Hi all,
Creating a DNS record (A record) is pretty straight forward in Powershell. I wonder if somebody knows how to create a little GUI with the powershell commands in the background to create DNS records.
For example something like a HTML form in where u can enter the DNS name, the Zone and the IPv4 address. Click Add and Powershell will add it on the background. I cannot find any good information on this when i google on it.
Thanks!

Tutorial on creating GUI with buttons?

Hi everyone,
I am a student in my second Java programming class and need to create a GUI that allows user input. After reading through the chapters assigned I'm still confused on how to do this. Does anyone know of a good web page/site that can give me some pointers?
Thank you very much for any pointers you can send my way.

HOW TO: Create a GUI "Hello World"


This document describes how to create and run a very simple "Hello World"
Java GUI app using JDeveloper. The application will have one button and one
text field. Clicking the button will populate the text field with the message,
"Hello World!"
Creating The New Application
In this section, we will create an application with an empty frame.
<ol>
[*]Choose File | New Workspace.
</li>
[*]Choose File | Save Workspace.
</li>
[*]Enter <TT>HelloGui.jws</tt> as the name for the workspace.
This creates a Workspace called HelloGui. A workspace organizes all the projects
you need to work on at one time.
</li>
[*]Choose File | New Project.
The Project Wizard opens. This wizard will help you create a new project called
HelloGui. A project contains all the files that go together in one "tier"--for
example, all the files belonging to a single Java Application client, or all
the files belonging to an Enterprise Java Bean. Because we are working on
a simple, one-tier application, we will only need one project in our workspace.
</li>
[*]If the Welcome page appears, click Next.
</li>
[*]On the Project Type page, in the What is the Project's Filename?
field, change the filename to <TT>HelloGui.jpr</tt>. Leave the rest of the
path the same.
</li>
[*]Select A Project containing a new... and choose Application
from the dropdown list.
</li>
[*]Click Next.
</li>
[*]On the Project Options page, in the What is the name of the project's
default package field, enter <TT>helloGui</tt>.
</li>
[*]Click Next.
</li>
[*]On the Project Information page, you can enter any information about your
project that you wish.
</li>
[*]Click Finish.
The Application Wizard opens.
</li>
[*]In the Class field, enter <TT>HelloApp</tt>.
</li>
[*]Select the New Empty Frame radio button.
</li>
[*]Click OK.
The Frame Wizard opens.
</li>
[*]In the Class field, enter <TT>HelloFrame</tt>.
</li>
[*]Click OK.
JDeveloper creates an application, <TT>HelloApp</tt>, containing an empty
frame, <TT>HelloFrame</tt>. The source code for these classes appears in the
Navigator, which is the upper left-hand pane in the JDeveloper IDE.
</li>
[*]Choose File | Save All.</li>
</ol>
Adding a Panel to the Frame
In this section, we will now add a panel to the frame. In the next section,
we will add all the other components to this panel.
<ol>
[*]In the Navigator, double-click <TT>HelloFrame.java</tt>.
A viewer opens. This viewer has four tabs at the bottom:
<ul>
[*]Source, the currently active tab, which displays the source code
of the selected class</li>
[*]Design, which invokes a visual layout designer</li>
[*]Class, which invokes an editor for the class' attributes, and
can help you stay JavaBean complient</li>
[*]Doc, which displays the class' JavaDoc
</li>
</ul>
</li>
[*]Click the Design tab.
The viewer now displays a grey square, a graphical mock-up of your frame.
Also, on the right-hand side of your screen, the Property Inspector opens.
This allows you to quickly set attributes and define events for components.
</li>
[*]In the component palette (the tabbed toolbar near the top of your screen),
select the Swing Containers tab.
</li>
[*]Click the blue square (described in rollover text as <TT>JPanel</tt>) and
click on your frame to add the panel.
The Property Inspector now displays attributes of the JPanel.
</li>
[*]In the Property Inspector, click twice inside the box beside the name
field.
</li>
[*]Change the name to mainPanel.
</li>
[*]Click the box beside the layout field.
</li>
[*]Choose XYLayout.
XYLayout is an easy-to-use Layout for prototyping. Later, we will change the
layout to a more portable one.</li>
</ol>
Adding Components to the Panel
In this section, we finish laying out a prototype UI. We will add polish and
portability to the UI later.
<ol>
[*]In the Component Palette, select the Swing tab.
</li>
[*]Select the <TT>JTextField</tt> component, which looks like a text field
with a cursor.
</li>
[*]In your panel, click and drag the cursor to outline the text field.
Don't worry if the text field doesn't have exactly the right size or position.
We will adjust these later.
The Property Inspector now displays attributes of the JTextField.
</li>
[*]In the Property Inspector, change the name (just as you did for the
JPanel) to <TT>displayField</tt>.
</li>
[*]Change the text to nothing (erase the value that is already there).
</li>
[*]In the Component Palette, select the <TT>JButton</tt> component, which looks
like a button being clicked.
</li>
[*]In your panel, click and drag the cursor to outline the button.
The Property Inspector now displays attributes of the JButton.
</li>
[*]In the Property Inspector, change the name and action command
to helloButton.
</li>
[*]Change the text to <TT>Say Hello!</tt>.
</li>
[*]Choose File | Save All.</li>
</ol>
Wiring Up the UI
In this section, we wire the UI so that clicking the button causes "Hello
World!" to display in the text field.
<ol>
[*]In the Property Inspector, select the Events tab.
</li>
[*]Click the box next to the Action Performed field and press the Enter
key.
This creates a method, <TT>helloButton_actionPerformed()</tt>, which will
be invoked when the button is clicked, and displays the source code for the
method stub in the viewer.
</li>
[*]In the viewer, add the following command to the body of the method:
<TT>displayField.setText("Hello World!");</tt>
</li>
[*]Choose File | Save All.</li>
</ol>
Testing the Prototype Application
<ol>
[*]Choose Run | Run "HelloApp".
Your application appears, with a blank text field and a button labeled "Say
Hello!"
</li>
[*]Click the button.
The text "Hello World!" appears in the text field.
</li>
[*]Close your application.</li>
</ol>
Refining the UI
In this section, we polish the UI so that the components have the right size
and alignment, the text in the text field shows up red, and the panel uses the
portable GridBag layout instead of the JDeveloper-specific XYLayout.
<ol>
[*]In the viewer, select the Design tab.
</li>
[*]Select your text field.
</li>
[*]Drag the edges of your text field until it is the size you want.
</li>
[*]Drag the center of the text field until it is the vertical position you
want.
</li>
[*]Right-click the text field and choose Align Center.
This centers your text field horizontally in the frame.
</li>
[*]In the property inspector, click the box next to the foreground field.
</li>
[*]Click the ellipses (...).
A color editor appears.
</li>
[*]Select Red from the dropdown list.
</li>
[*]Click OK.
</li>
[*]On your frame, select your button.
</li>
[*]Drag the right edge of your button until it is the horizontal size you want.
</li>
[*]Select your text field, and multi-select your button by control-clicking
it.
</li>
[*]Right-click your button or text field.
</li>
[*]Choose Same Size Vertical.
This sets the height of all selected components to that of the first selected
component (the text field).
</li>
[*]Right-click your button or text field.
</li>
[*]Choose Align Center.
This aligns the center of all selected components to that of the first selected
component (the text field).
</li>
[*]Select your panel by clicking anywhere on the grey background in the visual
designer.
</li>
[*]In the Property Inspector, click the box beside the layout field.
</li>
[*]Select GridBagLayout from the dropdown list.
</li>
[*]Choose File | Save All.</li>
</ol>
Running the Finished Application From Within JDeveloper
<ol>
[*]Choose Run | Run "HelloApp".
Your application appears, with a blank text field and a button labeled "Say
Hello!"
</li>
[*]Click the button.
The text "Hello World!" appears in the text field, in red.
</li>
[*]Close your application.</li>
</ol>
Deploying the Application to Your File System
<ol>
[*] In the Navigator, right-click <tt>HelloGui.jpr</tt> and choose New Deployment
Profile.
The Deployment Profile Wizard opens.
</li>
[*]If the Welcome page appears, click Next.
</li>
[*]On the Delivery page, select Web Application or Command-Line Application
from the dropdown list, and click Next.
</li>
[*]On the Staging Area page, in the Deployment Destination field, enter
<tt><JDeveloper>/HelloGui</tt>, where <tt><JDeveloper></tt>
is your JDeveloper root directory. Click Next.
</li>
[*]On the Project page, select all the <tt>.java</tt> files and click Next.
</li>
[*]Skip the Archive page and Applet Tags page by clicking Next on each.
</li>
[*]On the Libraries page, shuttle all libraries from the Project Libraries
list to the Deployed Libraries list, and click Next.
</li>
[*]On the Finish page, name the profile <tt>HelloGui.prf</tt>, and click Finish.
</li>
[*]When JDeveloper asks you if you want to deploy now, click Yes.</li>
</ol>
JDeveloper will archive your application files and copy this archive and all
other required libraries to <tt><JDeveloper>/HelloGui</tt>.
Running the Application from the Command Line
<ol>
[*]Open a command-line prompt.
</li>
[*]Enter the following script.
Note: You may want to create a batch file containing this script. Be
sure to replace JDeveloper_Home with your JDeveloper home directory.
<pre>set __CLASSPATH_ROOT_DIR__=JDeveloper_Home\HelloGui
set CLASSPATH="%__CLASSPATH_ROOT_DIR__%\HelloGui.jar"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\xmlparserv2.jar"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\classes12.zip"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\jdev-rt.zip"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\swingall.jar"
cd JDeveloper_Home\HelloGui
jre -cp %CLASSPATH% helloGui.HelloApp</pre>
</li>
[*]Your application appears, with a blank text field and a button labeled "Say
Hello!"
</li>
[*]Click the button.
The text "Hello World!" appears in the text field, in red.
</li>
[*]Close your application.</li>

Hello,
I followed your instruction step by step to make this "Hello World", but when I run it, I got message "cannot find the runable node". What do I miss here? Thanks.

Creating a GUI on a remote device.

I would like to create a GUI on a simple CCD touchscreen.The screen is effectively a dumb terminal that is connected to a pc using a proprietary data interface. The GUI needs to be created and rendered in an off screen buffer on the server with the data that constitutes repaint regions being sent to the LCD display.
I have thought about overriding the RepaintManagerI but that doesn't work when the display on the sever is not visible. I have thought about creating a custom GraphicsDevice and GraphicsConfiguration but I haven't had any success with this approach.
Has anyone done anything similar? Could anyone suggest a solution to this problem? I would be grateful for any help.
Thanks.

Hi -
I have a similar problem.
I have a small LCD controlled via the serial port. I have written a simple Java class to set or clear individual pixels on the display (it makes use of Java COMM to communicate with the hardware).
How would I go about turning this simple class into something that Java could use to render graphics on?
Obviously I could start writing a whole set of graphics routines for drawing lines, boxes, glyphs etc myself, but this is clearly wasted effort. How can I make use of the existing code to render graphics on a non-standard display?
Thanks for any suggestions!

Where can I find a good tutorial for mobile game developement with J2ME ?

Hi All,
I'm completely new to J2ME programming. But I have past experience on J2SE developement. Now I would like to know that where can I find a good tutorial for mobile game developement with J2ME ?
I'll be very greatful if I can find a useful step-by-step tutorial (eg. "The Java Tutorial" for J2SE)
Please point me ot the direction.
Thanks

ibook-widgets.com have a free tutorial book in the iBooks store. Search for "Create your first interactive book using iBooks Author" they also sell widgets.
I dont have any connection - I found their eBook in the store long ago and used it to learn more about iBA.
The best advice though, is be patient, go back over the process step by step, I cannot access the Help files for some reason.. but i am sure its in their.

Creating a GUI for use on an Ethernet Network

I'm designing a data logger to log voltage, current and temperature data on a reserve battery string while it's being charged. The logger will have the capability to be viewed remotely via Ethernet. With that said, I'd like some advice regarding the GUI for the remote PC which will be used to view the logger. Will it be easier to create the GUI using LabView or another high-level language (Java, C++ etc)? (Note: I have some programming experience in C (though I've never written/created a GUI) and I've never used LabView).
Solved!
Go to Solution.

Hi Joe1373. In general, for a small one-off project, I would suggest you go with a language you know.
In this case it sounds like whatever you choose you will have a learning curve, so I would recommend
LabVIEW if that is a possibility cost-wise. LV has a lot of built-in support for GUI development so
you can make realtively sophisticated GUIs without a whole lot of work/learning.
There are time-limited evaluation versions of LV available for download. I would take a look there, especially
the examples. Find something a little similar to what you want to do, then change the GUI on the
example to more closely match your ultimate objective to get a feel for the GUI development in LV.
This forum is a great resource with some very helpful developers, so come back with questions.
There are also many professional developers available to assist if you have a budget or inclination
towards that direction.

How to create a jdialog with boxlayout

Hi,
I was trying to create a jdialog as simple as plsql login dialog. In attempt to learn how should I proceed I downloaded and modified BoxLayoutDemo.java that is available from java's swing tutorial site:
* BoxLayoutDemo.java is a 1.4 application that requires no other files.
import java.awt.*;
import javax.swing.*;
import javax.swing.border.Border;
public class BoxLayoutDemo {
 static JDialog jdlg;
 public static void addComponentsToPane(Container pane) {
 pane.setLayout(new BoxLayout(pane, BoxLayout.Y_AXIS));
 addTextField(pane);
 addAButton("Button 1", pane);
 addAButton("Button 2", pane);
 addAButton("Button 3", pane);
 addAButton("Long-Named Button 4", pane);
 addAButton("5", pane);
 private static void addAButton(String text, Container container) {
 JButton button = new JButton(text);
 button.setAlignmentX(Component.CENTER_ALIGNMENT);
 container.add(button);
 private static void addTextField(Container container) {
 JTextField txt = new JTextField(20);
 //txt.setMaximumSize(new Dimension(100,20));
 txt.setPreferredSize(new Dimension(100,10));
 txt.setAlignmentX(Component.RIGHT_ALIGNMENT);
 //Border padding = BorderFactory.createEmptyBorder(20,20,5,20);
 //txt.setBorder(padding);
 container.add(txt);
 * Create the GUI and show it. For thread safety,
 * this method should be invoked from the
 * event-dispatching thread.
 private static void createAndShowGUI() {
 //Make sure we have nice window decorations.
 JFrame.setDefaultLookAndFeelDecorated(true);
 //Create and set up the window.
 JFrame frame = new JFrame("BoxLayoutDemo");
 frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 //Set up the content pane.
 jdlg = new JDialog(frame);
 addComponentsToPane(jdlg.getContentPane());
 //Display the window.
 frame.pack();
 frame.setVisible(true);
 jdlg.setPreferredSize(new Dimension(200,200));
 jdlg.pack();
 jdlg.setVisible(true);
 public static void main(String[] args) {
 //Schedule a job for the event-dispatching thread:
 //creating and showing this application's GUI.
 javax.swing.SwingUtilities.invokeLater(new Runnable() {
 public void run() {
 createAndShowGUI();
}The funniest thing is every thing except the text box is ok. With or without the text box the buttons are shown appropriately i mean they dont stretch. But in case of the text field it seems like that the height of the textfield becomes 60 instead of 20. if I use txt.setMaximumsize(new Dimension(100,20)) then everything seems ok.
Now it seems like swing has some fetish about textfields. Because even if I dont specify the size of the buttions they dont stretch themsleves but even if I specify the size of the text field and make it the first element so that the last element gets stretched if necessary without affecting it, it will defy the size instruction.Layout managers are really amazing!!!!!!!! and so helpful!!!!!!!!!

not really sure what effect you want, but try this
 private static void addTextField(Container container) {
 JTextField txt = new JTextField(20);
 //txt.setMaximumSize(new Dimension(100,20));
 txt.setPreferredSize(new Dimension(100,10));
 txt.setAlignmentX(Component.RIGHT_ALIGNMENT);
 //Border padding = BorderFactory.createEmptyBorder(20,20,5,20);
 //txt.setBorder(padding);
 JPanel p = new JPanel();//<-------------
 p.add(txt);//<-------------
 //container.add(txt);//<-------------
 container.add(p);//<-------------
 }

Oracle 10g is obsolete. Oracle 11g is already at terminal release.
Have you installed the Oracle rdbms software?
Installing Oracle and Building the Database
If you are going to be a professional DBA, you need to learn to
1) read the documentation
2) wean yourself from dependence on pictures and GUIs.
3) read the documentation
=================================================
Learning how to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
Go to docs.oracle.com.
Locate the link for your Oracle product and version, and click on it.
You are now at the entire documentation set for your selected Oracle product and version.
BOOKMARK THAT LOCATION
Spend a few minutes just getting familiar with what is available here. Take special note of the "books" and "search" tabs. Under the "books" tab (for 10.x) or the "Master Book List" link (for 11.x) you will find the complete documentation library.
Spend a few minutes just getting familiar with what kind of documentation is available there by simply browsing the titles under the "Books" tab.
Open the Reference Manual and spend a few minutes looking through the table of contents to get familiar with what kind of information is available there.
Do the same with the SQL Reference Manual.
Do the same with the Utilities manual.
You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
Then set yourself a plan to dig deeper.
- *Read a chapter a day from the Concepts Manual*.
- Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them (listed in your alert log) in the Reference Manual.
- Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
- *When you have finished reading the Concepts Manual, do it again*.
Give a man a fish and he eats for a day. Teach a man to fish and he eats for a lifetime.

 RAISE NO_CREATE_OBJECT.
 ENDIF.
it raised the sy-subrc = 2 this error is "Function call in SAP GUI with errors"
send to me how to handle this error.
Thank,

Hi Vijay,
We are facing the same issue.
Interestingly
From program's code only we are facing this issue.
If we display the program and Execute (Direct processing), it is working fine.
Can you please share how you resolved this issue.
Thanks

Best way to create a GUI (long)

Really not sure what I should be doing as far as GUI's are concerned, and the more I research, the more confused I get.
So far I have been using swing, with some awt thrown in, which doesn't seem too bad. Thing is that many people have mentioned better alternitatives, a few of which I have downloading right now. One concern I have is that if I learn a 3rd party api, it could stop being supported and could be hard to find docs; plus if I am going for a job, they probably wouln't care I have mastered Bob's leet toolkit, even if it really is the best thing out there.
Then again I could not learn an api at all, really not against a visual editor but think netbeans is the only free one, and I have never done it, and netbeans 4 wouln't run on my comp. Eclipse only does swt which seems only useful for apps, and I want this almost as much for applets as applications. Could check out JBuilder but I'm not sure what language it's based on (guessing swing?) Always loved Borland as a company so could see that as a way to go but that starts to get into money.
Then there's other weird things, like liveconnect and doing everything in html... and flash ???...
I definatly have a lot of research to do but hoping you guys could fill me in on what you use, have used, liked, disliked, ect. Maybe give me some kind of starting point, as well as see what everyones using. Interested to in those coming from the business end, what are employers / teams wanting?
Thanks,

So far I have been using swing, with some awt thrown
in, which doesn't seem too bad.Swing and AWT don't mix. Evil.
Thing is that many
people have mentioned better alternitatives, a few of
which I have downloading right now. One concern I
have is that if I learn a 3rd party api, it could
stop being supported and could be hard to find docs;Then don't, or at least go with the more common ones like SWT.
plus if I am going for a job, they probably wouln't
care I have mastered Bob's leet toolkit, even if it
really is the best thing out there.1) A prorammer should be able to work his way through any good API
2) Once again, stick with the few common APIs: Swing, AWT (if you have to) and SWT. I be that's what most companies use, and you're not limited to learning only one API.
3) Knowing APIs is one thing, knowing ergonomy a completely different one. You can build crap GUIs with any API; if you want to use your GUI-creating skills for your resume, you better learn that, too.
Then again I could not learn an api at all, really
not against a visual editor but think netbeans is theVisual editors are crap. You'lkl never be able to maintain their clumsy autogenerated code.
Then there's other weird things, like liveconnect and
doing everything in html... and flash ???...Yes?
I definatly have a lot of research to do but hoping
you guys could fill me in on what you use, have used,
liked, disliked, ect. I think no software project ever cared about what I like. I used GUIs according to their needs - if the customer wanted a web frontend, he got JSPs. If he wanted applets, he got Swing. Plus my apps have the GUI clearly separated from the business logic, so that any GUI is easily replacable by another one.
Maybe give me some kind of
starting point, as well as see what everyones using.
Interested to in those coming from the business end,
what are employers / teams wanting?They usually don't want anything. The customer wants.

Create business partner with role 'Internet User' via BP

Hi,
We want to create business partner with role 'BUP005 Internet User'
for purpose to link with created early user su01.
It's work via isauseradm application, Web UI.
Now I want to create new role 'BUP005 Interner user' via GUI. I started Tcode BP.
I filled USERNAME, password, roles. I tried to save BP.
I got this error:
Enter the Internet user
Message no. R11214
You have maintained attributes (logon data, roles and/or fixed values) for the Internet user, without having entered the Internet user itself.
But,
Field 'INTERNETUSER' is not changeble.
Denis.

Hi, DJ
Thank you for answer)
1. Have you saved the BP. If Yes, just see if the INTERNET USER maintained is available in SU01.
Yes, but I can not see INTERNET USER in the BP.
2. If you are not able to assign the INTERNET USER, please try to maintain the INTERNET USER in BP.
I can not do it, because I can not change field INTERNET USER
3. If the INTERNET USER field is not available, just check the authorization for the same.
I has all authorization: sap_all.

Help with J2ME streaming

Hi,
My name is Constantinos Loizou and I am a student and currently developing a project for my Master's degree.
I need to stream audio and/or video to a PDA device. There is a trick here which is:
The PDA must receive the stream from a multicast address. For this I have implemented a Bridge application which joins the multicast group on behalf of the PDA and receives the Multicast RTP packets (which are sent from JMStudio) and Unicasts them to the PDA.(HP iPAQ) I had no problem implementing this. The streaming is done using JMStudio player which encodes the streaming audio data into a number of encodings (DVI/RTP in my case). I choose DVI/RTP and stream a .wav audio file.
Now I have to accept the packets and play the stream on the PDA.
The j2me application receives all the RTP packets successfully and I can extract usefull information from the packets such as: Timestamp, sequence number, payload type. The payload type is 5 which means it is a DVI4 encoding therefor the packets are accepted without any problem. I then save the data of the packet into a byte[] array and in regular intervals (50 000 bytes) I load them into a new ByteArrayInputStream(buffer); When I try to load the BytearrayInputStream and open it with a player I get the following error message:
javax.microedition.media.MediaException: Failed to realize Player: Malformed wave media: expected 'RIFF'
at com.sun.mmedia.WavPlayer.doRealize(+160)
at com.sun.mmedia.BasicPlayer.realize(+84)
at src.ViewVideoCanvas.run(ViewVideoCanvas.java:112)
The command I run is: player = Manager.createPlayer(input, "audio/x-wav");//create new player
And the error occurs on player.realize();
I believe that this happens beacause the data is encoded to DVI/rtp. I have searched a lot and found the algorithm of decompressing the DVI data but again I get the same error
Anyway, this is a brief description of my problem and I hope you can help me.
Contact me for any more details or help you can provide (code sammples, decoding algorithms and implementations in java)
Thank you
Constantinos Loizou

Hi my name is shaun benjamin and I am sorry I dont have the solution to this problem but could you please do me a fovor.
