HI
I am new to JBoss and EJB development. I am stuck at one point for 2 days now,
I had been searching example documents but could not get any help so trying to
get soem help from forums.
Am trying to write a simple message driven bean (ejb 2.1 spec) and am using
jboss 4.2.3 and eclipse 3.4 IDE on windows vista OS.
I have implmented a ben class and have also implemented
javax.ejb.MessagDrivenBean abd javax.jms.MessageListener in my class. But when
I deploy the ejb to the server I see that the server log shows an error. And it
says can not find class MessageListener. It further says that the EJB code has
to implement the MessageListener intergface which I did. I have pasted my code
here could any one please let me know what the problem might be ????
| import java.util.Properties;
| import javax.ejb.EJBException;
| import javax.ejb.MessageDrivenBean;
| import javax.ejb.MessageDrivenContext;
| import javax.jms.Message;
| import javax.jms.MessageListener;
| import javax.jms.Queue;
| import javax.jms.QueueConnection;
| import javax.jms.QueueConnectionFactory;
| import javax.jms.QueueReceiver;
| import javax.jms.QueueSession;
| import javax.jms.TextMessage;
| import javax.naming.InitialContext;
| import org.jboss.logging.Logger;
|
| public class MessageBean implements MessageListener, MessageDrivenBean
| {
| public MessageBean() { }
| public void ejbCreate(){ }
| public void ejbRemove() throws EJBException { }
| public void setMessageDrivenContext(MessageDrivenContext arg0)
throws EJBException
| { }
|
| @Override
| public void onMessage(Message msg)
| {
| try
| {
| TextMessage txt = (TextMessage)msg;
| Logger log=Logger.getLogger("Message BEan log");
| log.info(txt.getText());
| System.out.println("MessageBean has received this message:"+txt.getText());
| }
| catch(Exception e)
| {
| e.printStackTrace();
|
| }
|
| }
| }
