As part of my application implementation I am doing following
1. MDB gets triggered when system finds message in Q
2. MDB calls Stateless Session Bean
3. Stateless Session Beans performs operations on CMP Entiry Beans as well as BMP entity beans in following sequence
tx = getSessionContext().getUserTransaction();
Perform operation with CMP Entity Bean 1
Perform operation with another Stateless Session Bean
Perform operation with CMP Entity Bean 2
Perform operation with CMP Entity Bean 3
Perform operation with BMP Entity Bean 4
if (tx.getStatus() !=
If there a problem in BMP, I want all operations to roll back.
Am I doing anything wrong? Because I am getting problem in my BMP (last step) saying that
"illegal attempt to use multiple resources that have only one-phase capability".
Any suggestions ??

You need to check the database driver classes configured for your datasource. They should be XA Drivers. For example, for Oracle database one should use oracle.jdbc.xa.client.OracleXADataSource.
Don't get me started about those stupid
