tweety sat [http://community.jboss.org/people/tweetysat] created the discussion "MDB - Obejctmessage exception" To view the discussion, visit: http://community.jboss.org/message/584552#584552 -------------------------------------------------------------- Hi. I'm quite new with jms.  I'm working with jboss 5.0.1. First step was to create a producer and a consumer application.  It's working fine.  I tried sending/receiving a textmessage and an objectmessage.  It's ok. Second step.  I'm trying to create a message driven bean.  It's working fine receiving a textmessage but NOT working with an object message. Perhaps you could help me. My object import java.io.Serializable; public class Student implements Serializable {     private static final long serialVersionUID = 1L;     private String name;     private String school;     public String getName()     {         return name;     }     public void setName(String name)     {         this.name = name;     }     public String getSchool()     {         return school;     }     public void setSchool(String school)     {         this.school = school;     }     @Override     public String toString()     {         return "Student [name="+this.name+",school="+this.school+"]";     } } My mdb package jms; import javax.annotation.Resource; import javax.ejb.ActivationConfigProperty; import javax.ejb.MessageDriven; import javax.ejb.MessageDrivenContext; import

                 }                ) public class ConsumerBean implements MessageListener {     @Override    public void onMessage(Message message)     {         Logger logger =

            {                 text = ((TextMessage)message).getText();             }             catch (JMSException e)             {                 e.printStackTrace();             }
