I have a session bean A who accessing two entity beans, (B and C). The session bean A try to insert new records into 2 tables by jndi look up those
2 entity beans, B and C.

Insert new records into B is successfully, but when insert new records into C I got exception came out, but JBOSS is not rolling back the records saved by entity bean B.

I am writing my program in this way:

//session bean method

public void insertNewRecords() throws Exception{

 //JNDI Look up to get B home interface and C home interface
 //insert records to B
 BHomeinterface.create(XXXXX);

 //insert records to C
 CHomeinterface.create(XXXXXXX, XXXXX);
}

Exception came out after I called "CHomeinterface.create(XXXXXXX, XXXXX);". According to JBOSS document, if I put " <transaction-type>Container</transaction-type>" in ejb-jar.xml, JBoss is supposed to handle transaction for me , right?

But why JBoss is not rolling back new records in B? It came out with still insert new records into B, and C no record insertion.

Am I doing someting wrong on transaction programming? Or I have to handle the transaction in program? Then what does JBOss do on helping handling transaction? It seems it does not work even I let JBOSS to handle transaction for me.
