[Tinyos-help] problem with MessageListener

Hi,

I'm using  Linux.
I try to run this :java TestSerial -comm serial@/dev/ttyUSB0:tmote

and I have:

Exception in thread "main" java.lang.NoClassDefFoundError:  
net/tinyos/message/MessageListener
	at java.lang.ClassLoader.defineClass1(Native Method)
	at java.lang.ClassLoader.defineClass(ClassLoader.java:620)
	at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124)
	at java.net.URLClassLoader.defineClass(URLClassLoader.java:260)
	at java.net.URLClassLoader.access$100(URLClassLoader.java:56)

	at java.lang.ClassLoader.loadClass(ClassLoader.java:251)
	at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319)

It must be a CLASSPATH problem,so I do as below;

root at m60:/opt/tinyos-2.1.0# find . -name MessageListener.class
./support/sdk/java/net/tinyos/message/MessageListener.class
root at m60:/opt/tinyos-2.1.0# echo $CLASSPATH

root at m60:/opt/tinyos-2.1.0# export  
CLASSPATH=$CLASSPATH:/opt/tinyos-2.x/tools/java
root at m60:/opt/tinyos-2.1.0# echo $CLASSPATH
:/opt/tinyos-2.x/tools/java

but I still have the same problem.
Any ideas?
Thanks and regards,
B.
