Exception in thread "main" java.lang.NoClassDefFoundError

Nice to meet you all! I'm a newbie at Java. I imported a project named ims-communicator and build project successfully using Eclipse . But when i tried to run jar file, i got this error:

ngu@MyUbuntu:~/workspace/ims-communicator$ java -jar ims-communicator.jar 
Exception in thread "main" java.lang.NoClassDefFoundError: javax/media/NoProcessorException
	at net.java.sip.communicator.SipCommunicator.<init>(SipCommunicator.java:126)
	at net.java.sip.communicator.SipCommunicator.main(SipCommunicator.java:423)

I tried to change the command a little but still got some problems

ngu@MyUbuntu:~/workspace/ims-communicator$ java -classpath -jar ims-communicator.jar 
Exception in thread "main" java.lang.NoClassDefFoundError: ims-communicator/jar

I'm using Ubuntu 10.10. Thanks for any reply

Check the documentation for this ims-communicator thing to see what dependencies it has and how it (and they) should be installed.

Basically the runtime error is saying that the javax.media.NoProcessorException class cannot be found. This class appears to be part of the Java Media Framework and either you have not installed this or it has not been configured so that the classes can be found when the jar file is run.

Wow! thanks so much! I finally got it run by downloading JMF for oracle.com and put in the right folder.

Great - I'm glad you've got it sorted out.
