Hi,
I have written the code to read messages from queue.But when i deploy this in weblogic 9.2 after creating a jar file it is showing unmarshaller failed Below is the code
MyMdb.java
package com.mdb.ejb;
import javax.ejb.EJBException; import javax.ejb.MessageDrivenBean; import javax.ejb.MessageDrivenContext; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage;
/** * Message-Driven Bean implementation class for: MyMdb * */
public class MyMdb implements javax.ejb.MessageDrivenBean,javax.jms.MessageListener {
/**
*
*/
private static final long serialVersionUID = 1L;
/**
* Default constructor.
*/
public MyMdb() {
// TODO Auto-generated constructor stub
}
/**
* @see MessageListener#onMessage(Message)
*/
public void onMessage(Message message) {
// TODO Auto-generated method stub
System.out.println("on two thtr ");
TextMessage textMessage = (TextMessage) message;
try {
System.out.println("\n\n\t(mdb) MyMDB Received \n"+ textMessage.getText());
SendMail.sendMail(textMessage.getText());
}
catch (JMSException e)
{
e.printStackTrace();
}
}
public void ejbRemove() throws EJBException {
// TODO Auto-generated method stub
}
public void setMessageDrivenContext(MessageDrivenContext arg0)
throws EJBException {
// TODO Auto-generated method stub
}
}
ejb-jar.xml
weblogic-ejb-jar.xml
It is shwoing below mentioned exception
