Class XaSessionManager

java.lang.Object
  |
  +--com.objectwave.transactionalSupport.xa.XaSessionManager

All Implemented Interfaces:

javax.transaction.xa.XAResource

public class XaSessionManager

extends java.lang.Object

implements javax.transaction.xa.XAResource

Support using Sessions as a compliant XAResource. The resources it manages are the DomainObject instances. This class is in the early stage of development - Whats important is that this resource somehow get associated with a TransactionManager transaction. Since that can be application server specific, I'll leave this as is for now.

  Example of how it may look. 


  XaSessionManager manager = new XaSessionManager(); 


  public void doSomethingNeedingManaged() { 

  TransactionManager tm = null; 

  try { 

  tm = (TransactionManager) new InitialContext().lookup("java:/TransactionManager");
  

  Transaction tran = tm.getTransaction(); 

  if( tran != null ) tran.enlistResource( manager ); 

  } 

  catch(Exception e) { 

  MessageLog.debug( this, "Failed to locate transaction manager", e); 

  }
