I am using
I have created a seam project using postgressql. The project builds as a war but will not deploy on jboss.4.2as.
It fails with
"Could not instantiate Seam component: entityManagerFactory".
Did you use New Seam Project wizard to create the project?
Could you check if the project is deployed correctly. Open JBoss Server View and see pop-up menu for JBoss AS/<your_project>. Select "Explore" there. Is there correct war?
Is there <project-name>-ds.xml file?
And please show us a full JBoss AS log.
