I have download a document-example.zip.
run "ant cmp-cd-compile". It compiled the sources and create an cd.jar file
copy "build-examples/cmp-cd/ejb/cd.jar" to the "deploy" subdirectory of the JBoss directory
could not create deployment: file:/D:/jboss/server/default/deploy/cd.jar
org.jboss.deployment.DeploymentException: Error in jboss.xml for Bean CDBean: configuration '' not found in standardjboss.xml or jboss.xml
I don't think the CD example is maintained anymore. Have you tried the examples that come with the quick start guide?
