We are using OJB 1.0.0 and JBoss 3.2.3 and got the simlar problem in first round. We got that error inside a transaction block. But after looking into the code we found it related to the errors caused by using the JDBC Connection outside the OJB persist code section.
if(queryType.equalsIgnoreCase("select")){ rs = stmt.executeQuery(sqlString); } else stmt.execute(sqlString); To run insert query with executeQuery(sqlString) will cause exceptions and OJB is still holding the connection but EJB layer is try to roll back. When we fix the code as above, we can get through without modifiy the jboss configuration.
