public interface ExternalTransactionController
```
Purpose: Interface for external transaction management.
Description: This interface represents a delegate to be used for external transaction management. The implementing class may interface to an OMG OTS service, a Java JTA service or a manufacturer's specific implementation of these services.
Responsibilities:
- Define the API for UnitOfWork to add a listener to the externally controlled transaction.

- Method Detail
  - beginTransaction
```
void beginTransaction(AbstractSession session)
```
    INTERNAL: Begin a transaction externally. This allows for EclipseLink to force a JTS transaction.
  - commitTransaction
```
void commitTransaction(AbstractSession session)
```
    INTERNAL: Commit a transaction externally. This allows for EclipseLink to force a JTS transaction.
  - getActiveUnitOfWork
```
UnitOfWorkImpl getActiveUnitOfWork()
```
    INTERNAL: Return the active unit of work for the current active external transaction.
  - getSession
```
AbstractSession getSession()
```
    INTERNAL: Return the manager's session.
  - registerSynchronizationListener
```
void registerSynchronizationListener(UnitOfWorkImpl uow,
                                     AbstractSession session)
                              throws DatabaseException
```
    INTERNAL: Register a listener on the unit of work. The listener will callback to the unit of work to tell it to commit and merge.
    
    Throws:
    
    DatabaseException
  - rollbackTransaction
```
void rollbackTransaction(AbstractSession session)
```
    INTERNAL: Rollback a transaction externally. This allows for EclipseLink to force a JTS transaction.
  - markTransactionForRollback
```
void markTransactionForRollback()
```
    INTERNAL: Marks the external transaction for rollback only.
  - setSession
```
void setSession(AbstractSession session)
```
    INTERNAL: Set the manager's session.
  - initializeSequencingListeners
```
void initializeSequencingListeners()
```
    INTERNAL: Initializes sequencing listeners. Always clears sequencing listeners first. There are two methods calling this method: 1. setSession method - this could lead to initialization of sequencing listeners only if sequencing already connected (that would happen if setSession is called after session.login, which is normally not the case). 2. in the very end of connecting sequencing, after it's determined whether sequencing callbacks (and therefore listeners) will be required.
  - getActiveSequencingCallback
```
SequencingCallback getActiveSequencingCallback(DatabaseSession dbSession,
                                               SequencingCallbackFactory sequencingCallbackFactory)
```
    INTERNAL: Returns sequencingCallback for the current active external transaction. DatabaseSession is passed for the sake of SessionBroker case. This method requires active external transaction.
  - clearSequencingListeners
```
void clearSequencingListeners()
```
    INTERNAL: Clears sequencing listeners. Called by initializeSequencingListeners and by sequencing on disconnect.
  - getExceptionHandler
```
ExceptionHandler getExceptionHandler()
```
    Return the exception handler used to handle or wrap exceptions thrown in before/after completion.
  - setExceptionHandler
```
void setExceptionHandler(ExceptionHandler exceptionHandler)
```
    Set an exception handler to handle or wrap exceptions thrown in before/after completion.
