Hi,


I would appreciate any help on this. I have tried so many ways but no success yet. I am trying to test a datasource inside an session ejb in JBoss AS 7.1.1.Final. Using MS SQL server.




Getting name not found exception, here is the stack trace. Please note in the code I am using the full JNDI name as java:jboss/datasources/ezsystemDS.


19:20:57,293 ERROR [stderr] (EJB default - 1) javax.naming.NameNotFoundException: jboss/datasources/ezsystemDS -- service jboss.naming.context.java.jboss.exported.jboss.datasources.ezsystemDS

When Jboss starts I can see datasources are bound correctly. Also verified that from JBOSS console naming tree view.

19:15:45,948 INFO  [org.jboss.as] (Controller Boot Thread) JBAS015874: JBoss AS 7.1.1.Final




Here is my ejb code




           public String echo(String input){
                        try {
                                        InitialContext ctx = new InitialContext();
                                        DataSource datasrc =  (DataSource)ctx.lookup("java:jboss/datasources/ezsystemDS");
                                        if(datasrc != null) {
                                                  Connection con = datasrc.getConnection();
                                                  con.close();
                                        }

                              } catch (Exception e) {
                                        // TODO Auto-generated catch block
                                        String x = e.getMessage();
                                        e.printStackTrace();
                              }
                        return "Echoing back " + input ;
    }



Data sources are configured in module.xml and created using admin console. Thanks.

What application is it. If you use ejb3 it might be easier to use injection with +@Resource+ to get a DS reference

https://community.jboss.org/people/wdfink Wolf-Dieter Fink,

Thanks. This is a ejb 3 app. I have tested with @Resource injection and DS reference working fine. My problem is I will be using Toplink native API to make database changes (No JPA). Toplink configuration is loaded from a sessions.xml file with a DS JNDI reference. Internally Toplink doing a context.lookup by datasource name. It was failing because of name not found exception. I was testing if JBOSS allows context.lookup by DS JNDI name.

I'm not sure, but this might be related to the ClassLoader as you are not inside of a EJB or even the application context (I suppose you use a module fro that)
