I'm using JBoss 3.2.1 and PostgreSQL 7.2and I'm also using the inheritance features of PostgreSQL. I've created a view and want to have an CMP entity bean that can perform queries on this view. I've used Middlegen to create the Bean but when I call a finder method I always get a NullPointer Exception. The reason is, that the queries aren't created correctly. The PostgreSQL Server log show the following: SELECT FROM personv So JBoss does not tell the DB server "what" to select. Has anybody already worked with Views and CMP? Any hints?
