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

public class InvocationManagedRuntime
extends AbstractManagedRuntime
implements ManagedRuntime, Configurable

Implementation of the ManagedRuntime interface that uses a static method call to find the TransactionManager. For example, to configure it to use IBM Websphere's TransactionManager, use the method:

Constructor Detail

InvocationManagedRuntime

public InvocationManagedRuntime()
Method Detail

getTransactionManagerMethod

public String getTransactionManagerMethod()
Return the method to invoke to get the TransactionManager.


setTransactionManagerMethod

public void setTransactionManagerMethod(String methodName)
Set the method to invoke to get the TransactionManager. E.g.: com.ibm.ejs.jts.jta.JTSXA.getTransactionManager


getTransactionManager

public TransactionManager getTransactionManager()
                                         throws Exception
Description copied from interface: ManagedRuntime
Return the TransactionManager for the managed runtime. This manager is used to register synchronization listeners, to map transactional PersistenceManagers to the current transaction, and possibly to enlist XA resources.

Specified by:
getTransactionManager in interface ManagedRuntime
Throws:
Exception

setConfiguration

public void setConfiguration(Configuration conf)
Description copied from interface: Configurable
Invoked prior to setting bean properties.

Specified by:
setConfiguration in interface Configurable

startConfiguration

public void startConfiguration()
Description copied from interface: Configurable
Invoked before bean property configuration is begun on this object.

Specified by:
startConfiguration in interface Configurable

endConfiguration

public void endConfiguration()
Description copied from interface: Configurable
Invoked upon completion of bean property configuration for this object.

Specified by:
endConfiguration in interface Configurable

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.

Specified by:
getRollbackCause in interface ManagedRuntime
Returns:
