Hi All,

I created a project "forgedemo3" with forge command console in Eclipse Kepler. When I tried to generate entities, I got the following error:

****ERROR*** An unexpected error happened during reverse engineering.org.hibernate.cfg.JDBCBinderException: Duplicate class name 'com.dliao.forgedemo.model.JobHistory' generated for 'org.hibernate.mapping.Table(HR.JOB_HISTORY)'. Same name where generated for 'org.hibernate.mapping.Table(HR.JOB_HISTORY)'*

Even though I specified with one schema (APEX_DBO) and one table (HOLIDAY). I don't understand why JBoss forge still looks for the JOB_HISTORY table under a different schema.

Here is the tailed log from Forge Console.

Thanks you, Dave
