The following code is used for finding out a datasource or ejb: InitialContext ic = new InitialContext(); datasource = (DataSource) ic.lookup(myJNDIName); Question is: in JBOSS, it convert ENC name to JNDI name in jboss-web.xml If my ENC for datasource is java:comp/env/jdbc/myDataSource, In Web.xml it is jdbc/myDataSource, in jboss-web.xml it is java:/myDB Then what should I use for lookup? myJNDIName should be "java:comp/env/jdbc/myDataSource" or "dbc/myDataSource" or "java:/myDB" View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3997674#...
