weblogic.jms. common.JMSException: Error deserializing object

Hi,

I am trying to put my own Serializable objects into a Topic.

I have a message driven bean listening on this and in the method onMessage, i try to cast the object received to the Serializable object sent.

I get the following error

weblogic.jms.common.JMSException: Error deserializing object

a:144)

(ObjectMessageImpl.java:305)


In my client program that publishes messages to a topic, the code looks like this

Result result = new Result();
result.setXXX();
........
logger.info( rslt);

I use the JMSAppender provided by the Log4j.

In my MDB, I write like this...


if (message instanceof ObjectMessage)
{
ObjectMessage m = (ObjectMessage) message;
Result rslt = (Result) m.getObject();
}


I get the Error deserializing object error at the line where i try to getObject() abd cast it to Result.

I use WebLogic 8.1.

Any help in this regard is appreciated.

Pri Vij,

From the looks of the stack trace your server code cannot find the org.apache.log4j.spi.LoggingEvent class. Do you have this class in the classpath of your server? I have never used the log4j JMSAppender but it looks to me like your server is going to need this class in order to deserialize the object.

later,
andy
