Hello, do i understand it correctly, 'Seam Generate Entities' does work for your databases, except for oracle? We have used it for generating entities out of our Oracle Express database. And we have it successfully used against Oracle 9. It was not an easy task for us to setup the database connection in a fully functinal way. But we succeded. In what i can remember, we have first tried to setup the oracle connection so that the 'hibernate' perspective does work in eclipse. In this perspective you get helpful information if something goes wrong. Ciao, Carsten View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4132396#...
