Javax.sound compare to javax.media in term of GUI

I messed around with javax.sound these few days and my emotions have been running up and down. I was happy that i could play mp3 on my software but after i decided to move on, i found out its impossible for me to obtain the length if i'm going to stream, and mp3 files are just too huge for clips to handle. this costs me a problem in doing the GUI for my software (one like winamp, windows media player, etc, etc)
I thinking of dropping javax.sound and moving into javax.media in hope for a much better version of sound handling. Anyone have any suggestion? or fix for my problem? I need help.
Thanks in advance,
KhinBoon

You may feel disappointed if you do so, I'm afraid.
I first tried the newly published mp3 codec for JMF.
It seems that it doesn't work on my RedHat Linux Advance Server3 update2.
On the other hand, I can play mpeg1 file over Internet using http protocol.
And I can also play mp3 file on another Wndows XP.
But the player can't realize when playing an mp3 file over the Internet.
I think that there's still a long way to go for JMF.

NoClassDefFoundError: javax/media/jai/PlanarImage

I am trying to run the JaiTut from the JAI and got the following error. Is this a classpath problem or what, I'm kind of new to this stuff.

IE6 causes java.lang.ClassNotFoundException: javax.media.pm.PackageManager

Guys,
I have an applet that simply plays a media file. Quite simple! It has been working fine for ages, but I recently upgraded to IE6, and BLAM! I now get this exception: java.lang.ClassNotFoundException: javax.media.pm.PackageManager
Of course, I have checked my classpath, and my path settings. I know that the classpath is fine, I can run JAVA JMStudio and it launches fine. The application runs OK as standalone. I can even debug the applet using JBuilder, and it works. As soon as I run it from IE6 - Nope.. Not working!
I wonder if anyone else has seen this? If I set the option to use the Sun JVM, the diagnostincs applet shows this:
JMF Diagnostics:
Java 1.1 compliant browser.....Maybe
JMF classes.....Not Found
but, if I set the option off, I get:
JMF Version... 2.1.1a
Win32 Build
Native Libraries Found
What is causing this difference? Is this even relevant? I have seen several other posts talking about a ClassNotFoundException but this is specific to IE6 (I think at least.) I will try and regress to 5.5 and keep you posted!
Steve

OK, Here is the deal..
Uninstall the JRE Plugin. (Delete the directory too)
Uninstall the JMF (Again, delete the dirs)
Remove any references to the JMF on the CLASSPATH
Reboot
Re-install the JRE Plug-in
Re-install the JMF.. Note: Make sure all options are checked when installing.
Reboot as requested .
Browse to: http://java.sun.com/products/java-media/jmf/2.1.1/jmfdiagnostics.html to test the installation.
Funilly, it all works now. The reason it did not work was due to the classpath being WRONG!!!
It now reads: C:\PROGRA~1\JMF21~1.1\lib\sound.jar;C:\PROGRA~1\JMF21~1.1\lib\jmf.jar;
BUT, I installed the JMF at: C:\Program Files\JMF2.1.1
Call me insane, but I do not have a clue why the paths do not match, but is solved my problem.
I am certain this clears several of the posts found on this Forum!!
Hope this helps you all..

(see the code below)
However, everytime I run the applet,
I get the message:

First and most obvious question is, what are you trying to have the applet view? The NoPlayerException generally means that JMF couldn't figure out how to display what you're telling it to display, be that an unknown codec, or unknown media type.

Creating a text with transparent background using javax.media.j3d.Raster

Hi, I'm trying to display a text in Java3D using the Raster but I'm not sure to make the background of the text transparent. Does anyone have any ideas.
Here's my code for creating the Raster image:
private javax.media.j3d.Raster getRaster(String str, boolean rotate) {
// Create an empty raster.
javax.media.j3d.Raster raster = new javax.media.j3d.Raster();
// Get a font metrics.
Font font = new Font("Times", Font.PLAIN, 12);
FontMetrics fm = getFontMetrics(font);
// Calculate the raster size.
int width = SwingUtilities.computeStringWidth(fm, str) + 6;
int height = 18;
// Create an BufferedImage.
BufferedImage image = new BufferedImage(width,
height,
BufferedImage.TYPE_INT_BGR);
// Draw the input string on the BufferedImage.
Graphics2D g2d = (Graphics2D) image.getGraphics();
g2d.setFont(font);
g2d.setColor(Color.WHITE);
g2d.drawString(str, 3, 14);
// Set the BufferedImage to the raster.
raster.setImage(new ImageComponent2D(ImageComponent2D.FORMAT_RGB, image));
raster.setSize(width, height);
raster.setType(javax.media.j3d.Raster.RASTER_COLOR);
raster.setCapability(javax.media.j3d.Raster.ALLOW_IMAGE_WRITE);
raster.setCapability(javax.media.j3d.Raster.ALLOW_SIZE_READ);
return raster;
Thank you for your help.

Hi,
If you create a new transparent imge you can put a color fill layer below the text layer and either turn off the layer visiblity for the color fill layer (eye beside the color fill layer in the layers panel)
or delete the color fill layer before saving the file as a transparent png.

Problem to find the javax.media.jai package

hi everyone!! it's not the first time I ask this question, but i have troubles to find javax.media.jai..
I've downloaded the jai 1.1 and everything is fine... However, I have to use classes from the javax.media.jai... I made the import, and it doesn't find it, as if it doesn't exist... Someone tells me that the jai contained it, so why doesn't it find it??
i'm using a java version 1.2.. do you think that is the problem?
thanks a lot, and sorry for my bad english!!
Anne.

thanks a lot!!! it helps me but doesn't resolve my problem!! ;o)
you may be right,, it's a classpath problem. well i work under unix, so i have to give my classpath by the command setenv CLASSPATH ...
i didn't find the jai_core.jar in my JAI 1.1, I have only the BugFixes.jar...
I tried to download the latest version of JAI, and unfortunately i have a new problem with the .tar, i don't manage to "open" it... the command
tar xvf [archieve file] gives me some errors!!
so I don't know what I'm gonna do.... I think I'm going to ask someone to send me the package, or the specific classes I need, it would be more easier!!
Thanks
Anne.

JAI installation problem, javax/media/jai/util/ not found?

Hi,
I am trying to use the JAI instllation in executing a class. However, I keep getting the following message.
Exception in thread "main" java.lang.NoClassDefFoundError: javax/media/jai/util/
I have added some jars from the JAI instllation to my classpath. However, I still get this message.
What jar file do I have to reference so I do not get this message?

Even more strange, I deploy it under Unix, there is no problem. The previous one is deployed
under Windowns XP. Anyone has same experience?

Javax.media.* not found!!

when i compile the a program, i get an error message "javax.media.*"not found! So, can any one tell me how to import this class to my compiler? i am use netbean 3.6. Thank u

Two- Options
1- This configuration is for Net Beans 3.5.1, I m not sure with 3.6
Go to
Tools > Options
In
Options
-----Building
----------------Compiler Types
----------------------------------External Compilation
In External Compilation select "Expert" Tab, In the class path field enter all the class related to the JMF, or if u r using Windows OS, just enter %CLASSPATH% OR -CLASSPATH.
Do the same in Internal Compilation.
And now in
-------Building
-----------------Debugging And Executing
--------------------------------------------Execution Types
Do the Same as in Compiler Types
2----- 2nd one is only the way if above does not work.
->Uninstall the NetBeans
->Install the JMF first
->Make sure the classpath environment variable is updated with JMF classes
->Now Reinstall this NetBeans
But I hope 1st will work.
I also have faced that problem, and recovered it by both of above ways

Import javax.media.* is not working

Hi,
I'm new to java and i was trying to create a media player using the javax.media package from the JMF. I installed it using the windows setup and it seemed to install correctly. Testing it with the java.sun.com applet tester worked. The media player is also working...
The only problem is that when i import javax.medis.* it gives me a compiler error:
package javax.media does not exist
my code is as follows:
import java.applet.*;
import java.awt.*;
import java.net.*;
import javax.media.*;
public class PlayerApplet extends Applet {
     Player player = null;
public void init() {
     setLayout( new BorderLayout() );
     String mediaFile = getParameter( "FILE" );
     try{
          URL mediaURL = new URL( getDocumentBase(), mediaFile );
          player = Manager.createRealizedPlayer( mediaURL );
          if (player.getVisualComponent() != null)
          add("Center", player.getVisualComponent());
          if (player.getControlPanelComponent() != null)
          add("South", player.getControlPanelComponent());
     catch (Exception e){
          System.err.println( "Got exception " + e );
public void start() {
     player.start();
public void stop() {
     player.stop();
     player.deallocate();
public void destroy() {
     player.close();
} Could someone please help me out here... i've tried all the few probable solutions... but to no avail...

Well changing the classpath to the correct one still didn't work.... but i still found the solution.
The Developer Environment that i use is JCreator and it seems it ignores the classpath and has its own settings for the class path... changing this also didn't work.
What worked was copying the Jar files from the JMF2.1.1e installed location into the path of the original classpath

"package javax.media does not exist" error message. Help!

May be this is a rookie problem, but I can't solve it by myself.
I'm using JBuider X to develop a GUI, and need to capture an image, from a web cam or so, and to save it in DB.
The problem is: I found some source codes wich are supposed to do this... but they references (imports) an javax.media class... and the JBuilder says that this class doesn't exists.
Can anyone help me?
Where can I get the class, and how I inform to JBuider where it's located?
Thanks in advance.

Project tab, "Build", Libraries -> import the JMF libraries. Something like that.

Javax.media.rtp.InvalidSessionAddressException:

Hi:
Using SIP Communicator Java client on Linux. (Redhat Enterprise 4 - WS).
Works fine when on local lan. I'm testing the client over VPN (Nortel/Apani Netlock client). It brings up an interface in the form:
nlv0: 10.61.x.x address
This address is returned as the selected local interface that the SIP client is attempting to bind the RTP Port to.
The specific error being received is:
Local Data Address Does not belong to any of this hosts local interfaces.
Does JMF not support VPN tunnels? if so how? What is the javax.media.rtp class code doing to determine that the VPN address brought up doesn't belong to my local machine?
Anyone know what to do here?
thx.
Duff

A workaround.
I set the address of my machine in my /etc/hosts to the machine name of the IP address that was assigned to the nlv0 address.
SIP client comes up fine now!
Bonus.

thank you.

Try:
http://java.sun.com/products/java-media/jmf/2.1.1/download.html
Yous should choose cross-platform java and in zip file you have
in directory :src\share\ packet source for javax, copy it to your
project directory and that's it...
I hope it helps...
