end

Designed to be put in a finally block instead of a rollback() in each catch block.

 Ebean.beingTransaction();
 try {
   // ... perform some actions in a single transaction
 
   Ebean.commitTransaction();
 
 } finally {
   // ensure transaction ended. If some error occurred then rollback()
   Ebean.endTransaction();
 }
