Hibernate Instantiation Failure On Serverside

I'm using a mysql database with hibernate that works perfectly locally. But when I deploy it on my server I get the following stacktrace. Please help:

"Caused by: java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter".

It seems that you have problems with class path of your deployed application.
