Class CommitException

A checked exception being thrown from CDOUserTransaction.commit() in case of commit problems such as commit conflicts.

This class is the root of an exception hierarchy that allows to determine and handle specific causes of commit problems:

    CDOTransaction transaction = session.openTransaction();

    for (;;)
    {
      transaction.getViewLock().lock();

      try
      {
        CDOResource resource = transaction.getResource("/stock/resource1");

        // Modify the model here...

        transaction.commit();
        break;
      }
      catch (ConcurrentAccessException ex)
      {
        transaction.rollback();
      }
      catch (CommitException ex)
      {
        throw ex.wrap();
      }
      finally
      {
        transaction.getViewLock().unlock();
      }
    }
 

Instances of this class indicate low-level technical problems such as database or network issues.
