java.lang.IllegalStateException: zip file closed

[Vilpesh Mistry]

Hello,

I am facing the problem in generating java code files from eclipse-JEE-indigo while using hibernate tool present in JBoss Tools.

My Setup :
1> Eclipse Java EE IDE for Web Developers. ( Version: Indigo Service Release 2 Build id: 20120216-1857 )
contains Hibernate Tools 3.4.0.v20120504-2121-H72-Beta3 org.hibernate.eclipse.feature.feature.group JBoss by Red Hat

I had downloaded eclipse indigo mentioned above and had got jboss tools installed over it from update site (http://download.jboss.org/jbosstools/up ... nt/indigo/)
-------------
I had created Hibernate Console Configuration and could see the tables in eclipse which were created in postgreSQL database.
Now i wish to generate the .java, .hbm.xml, DAO files using Hibernate Code generation Configurations.
When i run the code generation, it gives me following error.
