I've copied and pasted the example ejb-jar.xml and jboss.xml file from http://docs.jboss.org/jbossas/jboss4guide/r4/html/ch6.chapt.html#ch6.mdbejbjar.ex and I'm receiving the following error when JBoss attempts to deploy it:
ERROR [ScannerThread] deployment.MainDeployer (MainDeployer.java:943) - Could not create deployment: file:/...-ejb2.jar
org.jboss.deployment.DeploymentException: Error in ejb-jar.xml for M开发者_如何学Goessage Driven Bean TextMDB: expected one res-ref-name tag

at org.jboss.ejb.EJBDeployer.create(EJBDeployer.java:506)
Also, I've noticed in Eclipse that the sample ejb-jar.xml file I'm using doesn't conform to it's dtd. Is there a better sample ejb2 mdb I could look at?
Why don't you fix the deployment descriptor? Try this ejb-jar.xml
:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ejb-jar PUBLIC
"-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN"
"http://java.sun.com/dtd/ejb-jar_2_0.dtd">
<ejb-jar>
<enterprise-beans>
<message-driven>
<ejb-name>TextMDB</ejb-name>
<ejb-class>org.jboss.chap6.ex2.TextMDB</ejb-class>
<transaction-type>Container</transaction-type>
<acknowledge-mode>AUTO_ACKNOWLEDGE</acknowledge-mode>
<message-driven-destination>
<destination-type>javax.jms.Queue</destination-type>
</message-driven-destination>
<resource-ref>
<res-ref-name>jms/QCF</res-ref-name>
<res-type>javax.jms.QueueConnectionFactory</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</message-driven>
</enterprise-beans>
</ejb-jar>
Just another buggy example. Changing it to conform to the dtd fixes the problem.
From:
<res-ref-name>jms/QCF</res-ref-name>
<resource-ref>
<res-type>javax.jms.QueueConnectionFactory</res-type>
<res-auth>Container</res-auth>
</resource-ref>
To:
<resource-ref>
<res-ref-name>jms/QCF</res-ref-name>
<res-type>javax.jms.QueueConnectionFactory</res-type>
<res-auth>Container</res-auth>
</resource-ref>
