ejb testing issues with netbeans and openejb

Question

I have created a netbeans 6.7 EnterpriseApplication project with ejb and war modules with a test stateless session ejb with a simple sayHello() method.

I also added the openEjb library in order to unit test the ejb. Everything runs fine except that I keep getting the following error:

Turns out that I am getting the glassfish library webservices-tools.jar from somewhere somehow and I cant find out how to get rid of it so that I dont get the bunch of Exceptions whenever I try to run any junit tests.

Has anyone faced this issue before? Can you help me resolve it please?

Thanks.

Answer 1

well .. i was able to get rid of this error message .. but my method of doing so is more of a nasty hack .. i just removed the webservices-tools.jar file from the glassfish library folder and that fixed the issue.

Answer 2

OpenEJB 3.1.2 fixed that issue and can now successfully ignore class files that are not actually loadable by a standard classloader -- i.e. 1.0.com.sun.codemodel.ClassWriter is not a valid class name. Seems Sun puts some classes into a "1.0" directory for it's own internal purposes.

3.1.2 was just cut yesterday, the download page hasn't yet been updated. But the official release is available here:

http://www.apache.org/dist/openejb/3.1.2/

Hope this helps!
