You should get a LoggingEvent object from the JMSAppender. You can get all
serialized fields from it, including NDC, priority, thread name etc,
according to you layout pattern. If you are really expecting a layout
formatted string, you need to overwrite the JMSAppender#appender(Event).
Something like the following code block:
================================================================
public
void append(LoggingEvent event) {
if(!checkEntryConditions()) {
return;
}
try {
// Here you format the event before embed it into a JMS Message object
// You can also use a TextMessage instead of ObjectMessage
// TextMessage msg = topicSeesion.createTextMessage();
// msg.setText(this.layout.format(event));
ObjectMessage msg = topicSession.createObjectMessage();
msg.setObject(this.layout.format(event));
topicPublisher.publish(msg);
} catch(Exception e) {
errorHandler.error("Could not publish message in JMSAppender
["+name+"].", e,
ErrorCode.GENERIC_FAILURE);
}
}
================================================================
On the receiver side, you can extract the layout formatted string using the
following block
=================================================================
String loggings = (String)((ObjectMessage)message).getObject());
// or String loggings = ((TextMessage)message).getText());
=================================================================
If you tried it, please tell us the result.
Thanx,
Jin
