There are several versions of that plugin jar which are newer than the one you're using from 4 years ago.
If you upgrade to the latest Eclipse Mars.2 , released in March 2016, you can use this site  and install a much newer o.j.t.birt.oda plugin, version 1.8.0.Final-v20150924-2232-B33.
Can you please give me direct link of jar o.j.t.birt.oda plugin, version 1.8.0.Final-v20150924-2232-B33 so that i can download that jar.
I am facing same issue as package name got changed in hibernate.
Well, that's the newest release we have. Apologies!
Would you be able to cobble together a fix of your own, and submit it back to JBoss Tools so we can include it? If so, here are the sources in github:
AFAIK, the BIRT plugins use Hibernate 3.6.x. I believe that is what your problem is. I am not sure at this moment whether it is easily possible to support other Hibernate runtimes and if there is any room to implement this for the team. Maybe snjeza has an idea?
We could add a new ODA driver for Hibernate 4.1 and Hibernate 5.
Support for BIRT is no longer part of JBoss Tools as of 4.4 (for Eclipse Neon).
If you want this new feature, you're welcome to contribute it to the project.
