Hi Alexandre,

are you sure you don't have another version of cglib in your classpath different from the one used by lambdaj? In an indirect dependency maybe?

For sure at least hibernate uses cglib internally.

lambdaj uses version 2.2.2 of cglib.
Try to explicitly add it to your pom.

It's still doesn't work right now. I added the cglib 2.2.2 dependency

Try with lambdaj 2.3.3 and cglib 2.2.2. The error still there. I really don't understand this... Really strange.

i guess if you include the -with-dependencies artifact, there is a cglib
version already included, thus you'd need to exclude yours.

my suggestion: use the

<dependency>
<groupId>com.googlecode.lambdaj</groupId>
<artifactId>lambdaj</artifactId>
<version>2.4</version>

</dependency>

instead and keep your direct dependency to cglib in the pom.

The 2.4 version it's not on maven repo right now. So i tried with the 2.3.3 because I'm not using new features right now. But with 2.3.3 and cglib 2.2.2, this still doesn't work and every dependency are compile well.

I guess you could try to also exclude cglib from the hibernate's dependencies and all other projects using it.
After that I don't know what else you could do :(

Try using mvn dependency:tree to check the full tree of your dependencies.

cglib give asm:asm and my struts2-core gives asm:commons and asm:tree, Did you think that can conflict ? I'm really not sure because the error is a ClassNotFound on cglib/proxy

FOUNDED FINALLY ! With this site :
http://javarevisited.blogspot.ca/2011/06/noclassdeffounderror-exception-in.html

I look on classpath and everything was good. Until i see : lambdaJ-2.4.jar into my JVM/JRE/ext.

I think there was a conflict between this lib and the lambdaJ loaded with my pom.xml !

It's work fine now ! :)
