We are getting a NPE in the above class when attempting to instantiate the
class. What we think is causing the instantiation to fail is that the
Server (in this case Websphere) does not have authorization to access JMS
(actually MQ Series under that).
The failing code is in "openConnection()" which looks like this:
protected synchronized void openConnection()
{
try
{
m_connection = m_factory.createQueueConnection();
m_connection.start();
m_session =
m_connection.createQueueSession( false,
Session.AUTO_ACKNOWLEDGE);
m_sender = m_session.createSender( m_queue );
}
catch( final Exception e )
{
getErrorHandler().error( "Error starting connection", e, null
);
}
}
I think that it fails in createQueueConnection(), the code catches the
exception runs getErrorHandler() which then throws the NPE because the
error handler is not defined!
If you track through the code, the private variable ErrorHandler
m_errorHandler in AbstractTarget is never initialized.
I suspect the only way to resolve this sort of problem is to initialize the
field thus:
private ErrorHandler m_errorHandler = new
org.apache.log.util.DefaultErrorHandler();
Has anyone else seen this problem?
