You'll
need to use an ObjectMessasge, not a TextMessage, since the message consists of
a LogEvent object.

Subject: JMSAppender and the onMessage Impl
I have a working log4j configuration for the File Appenders. With a bit of help from this newsgroup I got the most of the JMSAppender working using Websphere 5 with a MDB. log4j is moving the data to the Websphere embedded Queue (Topic) however when the onMessage impl of my MDB tried to convert the sent log4j message passed in I get a Class cast exception.
The weird thing is if I use a straight topic call it works fine:
String msg = "Test Message";
topicPublisher.publish(msg);
Here is a code snipet. I have looked at other posts and have seen this type of usage. Not sure why I am different here
public void onMessage(javax.jms.Message message) {
try{
...
// Class Cast exception on the following line only from log4j
TextMessage textMessage = null;
textMessage = (TextMessage)message;
if(printStream==null){
setPrintStream(getLogFileName());
}
String msg = textMessage.getText();
if (!msg.equals("")){
printStream.println(msg);
printStream.flush();
}
}catch(JMSException e){
...
System.out.println(e.getLocalizedMessage());
}
}
# Log4j Properties
#------------------
log4j.rootLogger= DEBUG, JMS1
log4j.appender.JMS1 = org.apache.log4j.net.JMSAppender
log4j.appender.JMS1.TopicBindingName = jms/ESMTOPIC
log4j.appender.JMS1.TopicConnectionFactoryBindingName = jms/ESMTCF
log4j.appender.JMS1.layout = org.apache.log4j.PatternLayout
log4j.appender.JMS1.layout.ConversionPattern = [%-20d{M/d/yy HH:mm:ss.sss z}] %-25t:%-5p %-30c - %m%n
Right now I commented out the TestMessage lines and just log the actual object. I have to at least prove to the powers at be I am logging something.
