Import javax.media?

i have been trying to play a video from a application and i get a bunch of compile errors one is "package javax.media does not exist" because of this im getting 14 other errors, can anyone help me? i just downloaded and installed Java SDK 1.4.2 and i have jdk1.5.0_05 and jre1.5.0_05. so i should be up to date

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

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...

try compiling like this:
java -cp "." myTest
This is not compiling, here you execute the already
compiled myTest.java file (or it should be already
compiled). To compile you may want to use javac or any
other available compiler.Oops, sorry, I didn't mean compiling.
If you were able to compile ok, you can try running the program by using:
java -cp "." myTest
This usually will solve the problem when your program comples fine but can't find the class when you try to run it. It's almost like the compiler assumes to look in the current directory but the VM (java.exe) doesn't make this assumption.

Re: import javax.media.* question

Thank you very much.
I just downloaded the JMF package from java.sun.com and there is no compilation error.
Time to debug the program.
Thanks again.

Hi all,
I've installed JMF,

(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.

Javax.media Where download it?

Hi all.

Try:

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...

Javax.media.jai not in jmf.jar

Ive download JMF 2.1.1e from
http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/download.html
and installed it. However it does not seem to contain the javax.media.jai or com.sun.media.jai packages as per the documentation :-
http://java.sun.com/products/java-media/jai/forDevelopers/jai-apidocs/index.html
I checked the contains of the jmf.tar and and the other jars that came with the download
eg the following can not be found
import javax.media.jai.widget.ScrollingImagePanel;
import javax.media.jai.NullOpImage;
import javax.media.jai.OpImage;
import com.sun.media.jai.codec.SeekableStream;
import com.sun.media.jai.codec.FileSeekableStream;
import com.sun.media.jai.codec.TIFFDecodeParam;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageCodec;
So have I done something wrong, is this code no long in the jmf.jar, or is the documentation wrong ?

Thanks, that got me the jai_imageio.jar , however this jar does not contain the any of the following packages
import javax.media.jai.widget.ScrollingImagePanel;
import javax.media.jai.NullOpImage;
import javax.media.jai.OpImage;
import com.sun.media.jai.codec.SeekableStream;
import com.sun.media.jai.codec.FileSeekableStream;
import com.sun.media.jai.codec.TIFFDecodeParam;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageCodec;
are they in another jar that I have not included, or do I need to get them from somewhere else?

Import javax packages

i have installed JMF yet my programs show an error saying " cant import javax.comm" and cant import "javax.media.*". i would like to know how and where should packages be extracted so that the java program can access them.
thanx in advance.
regards.

javax.comm is a pain in the rear to install - the instructions haven't been updated since 1997, and windows 2k etc works differently from nt/95! You have to put all the files they mention in the appropriate places (they specify) in c:\program files\java\ etc rather than in c:\j2sdk1.4.1\... by the time I had finally figured this out (I'm not the fastest on the draw!) the damn files were everywhere on my hard-drive! Maybe something similar for media? Hope this helps, have a nice day :)

Javax.media, installing

Hi, I am trying to use:
import javax.media.jai.PlanarImage;
import javax.media.jai.Histogram;
But I keep getting an error, how do i install them? I am assuming i have to download a new developers pack, and how do I install it under eclipse?
Many thanks, Ron

I have the same problem, can you help to solve it?
I can't make work JMF in my linux box:
I have added these lines to my .bashrc script:
export JMFHOME=/usr/local/lib/JMF-2.1.1e
export CLASSPATH=$JMFHOME/lib/jmf.jar
export LD_LIBRARY_PATH=$JMFHOME/lib
Additionally I have make ln -s /usr/local/lib/JMF-2.1.1/lib/jmf.jar in
my /usr/local/lib/j2re1.4.2_01/lib/ext/ directory.
And
http://java.sun.com/products/java-media/jmf/2.1.1/jmfdiagnostics.html
always say me:
"JMF Version... 2.1.1e
All Java Build
Native Libraries Not Found"
What are "Native Libraries"?
Can you help me please?

Package javax.media doesnot exits

Hi,
I have installed JMF,but am still facing the error "package javax.media doesnot exits"
when i tried to import javax.media.*

You need to import JMF's library JAR files

Use of javax.media.jai

Hi all,
I wanted to use some classes of javax.media.jai but , I get this error which says
cannot resolve javax.media, I am using eclipse to write my code. Please let me know what I need to do.
Thank you.

Two things to check.
If your trying to actually use the JAI from javax.media.jai you need to
have the following import.
import javax.media.jai.JAI;
Also in eclipse you need to make sure that you have the package included in the project, and that your Class Paths are correct. If your class paths aren't correct then even if you have the package in the project you'll get errors.
Hope that helps.

Import javax.media?
