            I was looking at my server.log and found some messages like this one

            2005-02-14 17:17:14,551 DEBUG [org.jboss.ejb.EntityContainer] Failed to register cache as mbean
            javax.management.NotCompliantMBeanException: Class does not expose a management interface: org.jboss.ejb.plugins.PerTxEntityInstanceCache

            i think it is on startup of each entity bean container

            Hope this helps you to help me :-]

                I've runned JBoss under debugger and here's what my investigation shows: I'm calling instance per transaction BMP entity bean without a transaction context, by default it has a commit option C. Right after bean method invocation JBoss tries to passivate the instance, but fails because enterprise context is still locked, thus a perfectly valid(?) code generates lots of warnings.

                My code looks like this (schematically):

                MyInstancePerTransactionBean bean = home.findByPrimaryKey(...);
bean.method1(); //here we get passivation failure warning
bean.method2(); //and another one here

                (JBoss 4.0.3sp1)

                Here SWGroupsBean is an ordinary BMP bean, it's ejbFindByName method contains the code snippet shown above (method1 being getHierarchyName). As I said ctx is locked, so PerTxEntityInstanceCache.canPassivate returns false and we get a warning.

                Is it a bug or this warning is valid and I'm doing something wrong?
