Hello, I've got a strange exception with my EJB3.1 application, a ZipException is thrown during the application deployment:

I don't really know how to investigate this error; I know that it's not related to the glassfish installation (same problem on Ubuntu and Mac) ...

I spot a 'null' in the classpath definition (log level fine), maybe that's the reason, but I don't know how to get rid of it ...

(I'm using Netbeans 6.8, Glassfish v3, Servlet3, EJB 3.1, JPA/Hibernate)

Thank you for your help
