SessionFactory creation exception: NoSuchMethodError

Hello....

I am trying to use Hibernate in my Struts2 project, but when I run the application, this error occurs:

Initial SessionFactory creation failed.java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.<init>(Z)V

All web pages I have found related to this error, suggest about a version mismatch in asm libraries, but I doubt this is my case.

I use NetBeans 7.2.1 and I added Hibernate library. When I did it, a lot of Hibernate libraries were actually added, including ASM library. So I think all those libraries has the matched versions.

Any other hint on this, please?

Thanks a lot
Jaime

I also think it is a version mismatch issue.
Which version of Hibernate and ASM do you use?
Also to notice is, that with Java7 org.objectweb.asm.ClassWriter has become part of the SE-JRE,
so be aware that, if you use Java7, the adding of a asm.jar in your classpath gets practically ignored.
