I am using Hibernate 3.2 and JAX-RS 1.0.2 web services for running some web services to add users to a database. I am using MyEclipse 7.5.

When I try accessing the project if the data is verified ok and is to be added to the database the following Exception crops up:
java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter

It looks like the missing method comes from the asm.jar with Hibernate 3.2.4 and the error occurs with both the built in Tomcat 6 that comes with MyEclipse and the Tomcat 5.5.17 server I have to mirror the deployment server. Are these JAR files bundled with the project or should they be copied over seperately for these servers?

Please advise.

Full exception in the next post.

Got the issue I think – Hibernate 3.2 uses an asm.jar v1.5.3 and the JAX-RS web services use asm-3.1.jar which I think generates the conflict.

igemini,
The work around is posted in the following link
http://www.hildeberto.com/2008/05/hibernate-and-jersey-conflict-on.html
To modify your jar files you need to go to
Windows > Preferences > MyEclipse Enterprise Wrokbench > Project Capabilities > Hibernate
Please note that the changes will effect all the projects in the workspace. You can revert the changes by clicking “Restore Defaults”
Let me know if that helps.
