Creating custom javax.jms.Message class

[snavjot]

Hi,

I have

public interface EmailMessage extends TextMessage
{
private String from;
private String to;
private String subject;

// getter setter follows
}

then i have

public class EmailMessageImpl extends com.sun.jms.TextMessageImpl implements EmailMessage
{
...
...
}


Now, in my SLSB, when i write
EmailMessage em = new EmailMessageImpl();

Jboss gives me error on runtime, NoClassDefFoundError - EmailMessageImpl.

I have checked it's in my ejb jar. And i tested calling constructor from another class. That works.

So, i check the TextMessageImpl. It has empty public constructor. Then i checked com.sun.jms.MessageImpl also has empty constructor.

Now, in API terms, you create message from Queue/TopciSession,

Do i have to extend QueueSession and add createEmailMessage()?
OR
Do i have to extend TextMessageImpl of Jboss's SpyMQ i.e. SpyTextMessage (if i am not wrong)


Please correct me if am thinking in totally wrong direction.



I have made my code working by switiching to MapMessage as of now but i would really like a custom jms message.

JBossMQ has no mechanism for adding custom message types,
any custom message will be downcast to whatever interface it extends
i.e. javax.jms.TextMessage

Your NCFE is probably because you are missing the sun class?
