Iam trying to implement a read only entity bean. I have set the read-only tag in the jbosscmp-jdbc.xml to true. According to the jboss documentation, this will not let me create or update records in the database for that bean. But, Iam able to create new records. I also removed the read-only tag from the standard jbosscmp-jdbc.xml. So, Iam reconsidering moving all my read only code to DAO's instead of entity beans. Appreciate your help.
