NoClassDefFoundError: org/objectweb/asm/CodeVisitor

[karol_lo]

I'm missing class org.objectweb.wsm.CodeVisitor. I use library asm-2.2-bin.jar but none of packages contains this class. Where can I get library with this class included.

thx...

I don't know about asm 2.2 but it's present in asm 2.1; asm comes in different packed jar and probably you haven't downloaded the full one. If you are using cglib there is a _nodep version which includes the needed classes from asm so you don't need them anymore.

I also ran into the same problem. This is what the message returns.

I already placed the cglib_nodep.jar package in the classpath. How do I fix this problem?

Thnx in advance.

[Andreas Senft]

Perhaps there is a second cglib jar hanging around in your classpath. Maybe from hibernate or some other lib that also uses Cglib. If that comes first in the classpath and is an incompatible version it might well cause that problem.

Regards,
Andreas

I had this problem after updating to hibernate 3.1.3, which ships with an updated asm jar with the CodeVisitor class retired. I solved it by using the cglib jar from Spring, instead of the one from hibernate. The cglib jar coming in Spring specifically has all the old asm classes rolled up in itself.
