I have used log4j to send LoggingEvent object through JMS to Weblogic 5.10, 6.0, and 6.1, but have never seen a problem such as this.
Not quite sure what you mean by "assigning the categoryName ... during deserialization". What are the steps you are performing when this occurs? ----- Original Message ----- From: "Marvin Chase" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, June 10, 2002 12:17 PM Subject: LoggingEvent ClassCastException > Guys, > > I'm experiencing a strange class cast exception when deserializing a > LoggingEvent.
