Hi,
A normal exception doesn't automatically
rollback the transaction.
Only Errors, RuntimeExceptions and RemoteExceptions are handled by the
server.
You request a rollback using the EJB context.
SessionContext ctx;
public void setSessionContext(SessionContext ctx)
{
this.ctx = ctx;
}
try
{
...
}
catch (ServiceLocatorException sle)
{
logger.fatal("importArchive() failed", sle);
ctx.setRollbackOnly(); // !!!!!! HERE !!!!!!
throw new TransferException("Transfer::importArchive() failed with
ServiceLocatorException", sle);
}
