java.lang.NoClassDefFoundError

[Antony]

Hi,

I try to compile the Basic Exemple in command line, but i still have this error. I search on google and find that i need to change my classpath. I try to change it, but nothing changes :

[15:22:31][anto@jupiter] ~/bot_msn_wikipedia/java/jml/example/net/sf/jml/example$ set $CLASSPATH=.:/home/anto/bin/jdk1.6.0_02/

I already try /home/anto/bin/jdk1.6.0_02/bin/ /home/anto/bin/jdk1.6.0_02/lib/ etc...

[15:22:50][anto@jupiter] ~/bot_msn_wikipedia/java/jml/example/net/sf/jml/example$ java BasicMessenger                            Exception in thread "main" java.lang.NoClassDefFoundError: BasicMessenger (wrong name: net/sf/jml/example/BasicMessenger)
