Can not run a project with modified jmf.jar

Question

Hi,
my project use the modified jmf.jar in which all classes leading with path 'javax' were deleted
and all the classes of the package com.ms.security(which is in windowDirectory ex: C:\WINNT\java\Packages)
were included.
I download the source code file:jmf-2_1_1e-scsl-src.zip and unzip it,
I only use the directory 'javax'
which is located at the directory of share of src of the unzip Source code file.
I put the above directory 'javax' and AVTransmit2.java in src directory of my project.
The main in AVTransmit2.java was modified as:
public static void main(String[] args) {
Format fmt = null;
AVTransmit2 at = new AVTransmit2(new MediaLocator("file:/d:/back.avi"),"255.255.255.255","42050",fmt);
String result = at.start();
if (result != null) {
System.err.println("Error : " + result);
System.exit(0);
System.err.println("Start transmission for 60*20 seconds...");
try {
Thread.currentThread().sleep(60000 * 20);
catch (InterruptedException ie) {
at.stop();
System.err.println("...transmission ended.");
System.exit(0);
I get the error:
============================================================
IOException in readRegistry: java.io.InvalidClassException: javax.media.format.AudioFormat; local class incompatible: stream classdesc serialVersionUID = -9207570564778637264, local class serialVersionUID = -3901555183512636654

Error : Couldn't create processor

somebody can show me what is wrong ?
Thanks

What I think is happening is that the new jar files which you are using are interfearing with the stream. So basically one part of your program is looking for the standared class and your jar files are giving it a different version. Whats complicating this problem is that the classes you are refrencing implement Serializable, so unless you are able to trick the program into thinking that the old .jar files and the new .jar files have the same serialVersionUID your going to have to use the old jars.
