Hi Guys I am using JBoss 4.0.5 +eclipse
I wrote a simple Message driven bean Firstly i tried without using any deployment descriptors....It gave me this error:

WARN [MessagingContainer] No message-driven-destination given; using; guessing type
09:33:58,162 WARN [MessagingContainer] Could not determine destination type, defaults to: javax.jms.Topic
09:33:58,178 WARN [ServiceController] Problem starting service jboss.j2ee:ear=JMS1.ear,jar=JMS1.jar,name=SimpleMessageDriven,service=EJB3

Then i wrote ejb-jar and jboss xml files
The contents of these files are like this:
ejb-jar
<ejb-jar version="2.1"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd">

<resource-ref>
<res-type>javax.jms.QueueConnectionFactory</res-type>
</resource-ref>
</message-driven>
</enterprise-beans>
</ejb-jar>


JBoss


<enterprise-beans>
<message-driven>
<ejb-name>SimpleMessageDriven</ejb-name>
<destination-jndi-name>queue/B</destination-jndi-name>
<resource-ref>
<res-ref-name>jms/QCF</res-ref-name>
<jndi-name>ConnectionFactory</jndi-name>
</resource-ref>
</message-driven>
</enterprise-beans>



Now i am getting This error:

INFO [EARDeployer] Init J2EE application: file:/C:/jems-insatalledJBossServer/server/default/deploy/JMS1.ear
10:56:14,158 WARN [ServiceController] Problem creating service jboss.j2ee:service=EJB3,module=JMS1.jar
org.jboss.xb.binding.JBossXBException: Failed to parse source: cvc-complex-type.2.4.a: Invalid content was found starting with element 'acknowledge-mode'.



I am doing in EJB 3.0 .I heard that for ejb3.0 no deployment descriptors needed....

Please help me in removing this bug....
Any tutorials or links are welcome...

Thanks in advance...
