[jboss-user] [Messaging, JMS & JBossMQ] - My problem about JMS & MDB !
Hi all!
I read about JMS and MDB inside "Mastering. EJB.4th.Edtion" (chapter 7). I use
anonymous wrote : jboss-4.0.5.GA and EJB 3.0
I writed a Message Driver Bean, look like:
| public class LogBean implements MessageListener {
| public LogBean() {
| System.out.println("LogBean created");
| }
| public void onMessage(Message msg) {
| if (msg instanceof TextMessage) {
| TextMessage tm = (TextMessage) msg;
| try {
| String text = tm.getText();
| System.out.println("Received new message : " + text);
| } catch (JMSException e) {
| e.printStackTrace();
| }
| }
| }
|
| public void remove() {
| System.out.println("LogBean destroyed.");
| }
| }
And, I have ejb-jar.xml:
...
| <enterprise-beans>
| <message-driven>
| <ejb-name>LogBean</ejb-name>
| <ejb-class>mdb.com.LogBean</ejb-class>
| <messaging-type>javax.jms.MessageListener</messaging-type>
| <transaction-type>Bean</transaction-type>
| <message-destination-type>javax.jms.Topic</message-destination-type>
|
| <activation-config>
| <activation-config-property>
|
<activation-config-property-name>destinationType</activation-config-property-name>
|
<activation-config-property-value>javax.jms.Topic</activation-config-property-value>
| </activation-config-property>
| </activation-config>
| </message-driven>
| </enterprise-beans>
But when I deploy it on JBoss server, I received some errors:
org.jboss.deployment.DeploymentException: Required configproperty
RequiredConfigPropertyMetaData@19238ad[name=destination
descriptions=[DescriptionMetaData@147ff11[language=en]]] for messagingType
'javax.jms.MessageListener' not found in activation config
[ActivationConfigProperty(destinationType=javax.jms.Topic)]
ra=jboss.jca:service=RARDeployment,name='jms-ra.rar'
| ....
I think that I must configure JBoss but I don't know where I do this ? Please guide
to me or show me some documents about this problem.
Thanks very much.
