Hi I have some problems to deploy EJB3 on JBOSS 4..0.5, abd a Oracle8i databse. "DATABASE" I have one instance of my database, and two schema " SCH1" and "SCH2", I'm log on SH1 and each Schema has any table. but I have to create a ejb entity SCH2_TABLE1, TABLE1 is a table of SH2, in the TABLE1 script : GRANT SELECT ON TABLE1 TO SCH1; .. When I try to deploy, I have an Oracle exception : ORA-01031: insufficient privileges My question is, what are the privileges required to deploy an EJB3 entity on an Oracle database or Schema? An other question, if I don't declare my entity in the persistence.xml, jboss find my entity and try to deploy it...is it normal?? What is the use of the persistence file? I know it use to declare the oracle-DS file and the name of the database, and also the mode of persistence (update, create-drop)... but how it can find my entity without any declaration?
