Hi, I use JBoss IDE (XDoclet) to generate my CMP EJBs, and HSQQLDB as database. I have 2 EJBs, Groups and Roles. A groups can have many roles and a role can have many groups. There is a relation table between them, GroupsRolesLink.
The first time I deploy them, the container creates the tables, the contraints and the indexes correctly. The second time I deploy them, I have the following error | 18:16:54,811 ERROR [EntityContainer] Starting failed | org.jboss.deployment.DeploymentException: Error while creating table; - nested throwable: (java.sql.SQLException: Index already exists in statement [CREATE INDEX roleId_idx0 ON GroupsRolesLink (roleId)]) | at

I don't undestand why this woks the first time and not the second one ! Can someone explains to me how JBoss works on that case, and what is the solution ?
