Re: [teiid-dev] Hibernate reverse engineering

Mike, I got this to work in JBoss Tools, I'm sure there it can be done in the ant tasks as well. I need to follow up with Max to see if there is a more correct way to do this, but if you add the teiid dialect that is delivered in the client directory of Teiid to the global eclipse classpath, reveng works. In JBoss Tools navigate to Window->Preferences->Java->Installed JRE's. Select the current JRE and click the Edit button. Click Add External Jar and navigate to the teiid-hibernate-dialect jar. ~jd ----- "Ted Jones" <tejones(a)redhat.com&gt; wrote: > FWIW, I was able to reverse engineer using JBossTools 2.0.1 and Teiid > 6.2.
