Don't know if you found your answer or not, but check this out: http://docs.jboss.org/ejb3/app-server/tutorial/ As described in the injection section, you can do the following: The @javax.annotation.Resource annotation allows you to inject resources. @Resource(mappedName="DefaultDS") private javax.sql.DataSource ds; If you just need String data, it would look like so: @Resource(mappedName="MyConfigValue") private String somevalue; If you're not using the annotations, just declare a resource in the ejb-jar.xml for you mdb, then do a jndi lookup on it in your bean.
