Class WASManagedRuntime

java.lang.Object
  extended by org.apache.openjpa.ee.AbstractManagedRuntime
      extended by org.apache.openjpa.ee.WASManagedRuntime
All Implemented Interfaces:
ManagedRuntime, Configurable

public class WASManagedRuntime
extends AbstractManagedRuntime
implements ManagedRuntime, Configurable

ManagedRuntime implementation that allows synchronization with a WebSphere managed transaction.

WebSphere Application Server does not expose the TransactionManager to an application. Instead it provides a proprietary interface to register for synchronization and obtain transaction ids.

WASManagedRuntime provides the wrapper classes needed to interact with the WAS proprietary interface and the OpenJPA kernel.

Method Detail

getTransactionManager

public TransactionManager getTransactionManager()
                                         throws Exception
Gets an extendedJTATransaction from JNDI and creates a transaction wrapper

Specified by:
getTransactionManager in interface ManagedRuntime
Throws:
Exception

setConfiguration

public void setConfiguration(Configuration conf)
Caches a copy of the configuration. The configuration is used to obtain the logger and classloader.

Specified by:
setConfiguration in interface Configurable

endConfiguration

public void endConfiguration()
EndConfiguration stub.

Specified by:
endConfiguration in interface Configurable

startConfiguration

public void startConfiguration()
StartConfiguration stub.

Specified by:
startConfiguration in interface Configurable

main

public static void main(String[] args)
                 throws IOException
Throws:
IOException

setRollbackOnly

public void setRollbackOnly(Throwable cause)
                     throws Exception
Description copied from interface: ManagedRuntime
Sets the rollback only flag on the current transaction. If the TransactionManager is capable of tracking the cause of the rollback-only flag, it will also pass along cause information.

Specified by:
setRollbackOnly in interface ManagedRuntime
Parameters:
cause - the Throwable that caused the transaction to be marked for rollback, or null of none is known
Throws:
Exception

getRollbackCause

public Throwable getRollbackCause()
                           throws Exception
Description copied from interface: ManagedRuntime
Returns the Throwable that caused the current transaction to be marked for rollback, provided that any exists.
