I'm using: - Eclipse Elios Release 2 with the latest JBoss Tools - MySQL 5.5.9 - Seam 2.2.2.Final - JBoss 5.1.0.GA
I had a working project created with JBoss Tools (one project splited in 5 subprojects with maven integrated - EAR, EJB, WAR, TEST and WAR-PARENT)
I've just added an entity to map a new database table and this is the error message I got:
21:12:22,751 ERROR [AbstractKernelController] Error installing to Start: name=persistence.unit:unitName=index-ear.ear/index-ejb.jar#index-war state=Create java.lang.UnsupportedOperationException: The user must supply a JDBC connection
I can't figure out what had broken my project that way! I've even deleted my today's modifications to get back to the last working files and it still doesn't want to work.
