    Referenced datasource not found with JBoss 5.0 (Beta4)

    Fabian Depry Newbie

      Hi,

      We are currently using JBoss 4.2.2 but we are trying to make our application work under JBoss 5.0.

      We are using a WAR file as well as an EAR file containing our EJB jar file.

      We defined our datasource as a JNDI resource in a "-ds.xml" file in the deploy directory; it seems to be correctly deployed both under 4.2.2 and 5.0.

      That data source is accessed by our application through a reference that is defined in web.xml:

       <resource-ref>
       <res-ref-name>app-specific/datasource</res-ref-name>
       <res-type>javax.sql.DataSource</res-type>
       <res-auth>Container</res-auth>
       <res-sharing-scope>Shareable</res-sharing-scope>
       </resource-ref>
      


      The mapping between the resource reference name and the JNDI name is in our jboss-web.xml file:

       <resource-ref>
       <res-ref-name>app-specific/datasource</res-ref-name>
       <jndi-name>java:/app/datasource</jndi-name>
       </resource-ref>
      


      This set-up used to work under JBoss 4.2.2 but doesn't work anymore under JBoss 5.0; it complains that the datasource is not bound:

      Caused by: javax.naming.NameNotFoundException: app-specific not bound
      


      I know JBoss 5.0 is still Beta; I was just wondering if anybody else ran into this problem too...

      Thanks!

          Please post the entire exception stacktrace, the contents of your -ds.xml and also the code where you are looking up the datasource.

            Here is the full stack trace. This happens after the EJB deployment (which is fine), then Tomcat deploys the WAR and our Servlet entry point is being executed; it tries to access our database (Oralce) and the exception happens:

            javax.ejb.EJBException: com.imsweb.seerdms.shared.exception.SeerInvalidStateException: Unable to get connection.

            Here is our datasource file:

            <datasources>
             <local-tx-datasource>
             <jndi-name>app/datasource</jndi-name>
             <connection-url>jdbc:oracle:thin:@some.address:1521:app</connection-url>

            </datasources>
            


            This is the code that provides the connection, the first method is actually throwing a NamingException that is catch by some other code, but this is the root of the problem:

             public Connection getConnection() throws NamingException, SQLException {
             DataSource dataSource = (DataSource)lookup(DataSource.class, "java:comp/env/app-specific/datasource");
            
             return dataSource.getConnection();
             }
            
             protected Object lookup(Class<?> clazz, String name) throws NamingException {
            
             //- Obtain a cached initial context
             InitialContext context = new InitialContext();
            
             try {
             Object objRef = context.lookup(name);
             return PortableRemoteObject.narrow(objRef, clazz);
             }
             finally {
             context.close();
             }
             }

              jaikiran pai Master

              Is it a case of your init servlet being invoked even before the ENC is initialized (or maybe even before the datasource deployed). I have seen posts about JBoss-5 has issues related to deployment and deployment ordering. Do the logs show that the datasource is bound before the servlet is called? Can you post that part of the logs?

                There is a message about the connection being bound to the JNDI name, so I know this is successful and done before the exception:

                15:27:26,446 INFO [ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=app/datasource' to JNDI name 'java:/app/datasource'
                


                Here is the full log (I removed some EJB messages because we have many of them).

                  Let me see if I understand this correctly. You have a data source named "java:/app/datasource", and the code to open the data source thinks that it is named "java:comp/env/app-specific/datasource"?

                  Maybe the person who wrote the *-ds.xml file should get together with the person who wrote the Java code and agree to use the same name. ;-)

                    I think what "depryf" is trying to do is, define a resource-ref named "app-specific/datasource" for the "java:/app/datasource" datasource and then use java:comp/env/app-specific/datasource as the jndi-name for looking up the datasource.

                    depryf,

                    Going by the exception stacktrace, i guess this is what is happening:

                    You have a resource-ref defined in your web component, in which you have a startup servlet. This startup servlet will then have access to the java:comp/env/app-specific/datasource datasource. Based on the exception stacktrace, i can see that in the init method of your startup servlet you are looking up an EJB and invoking an method on the EJB. The EJB then (i guess through a DAO) tries to lookup the datasource using java:comp/env/app-specific/datasource jndi-name. This is not going to work because, the EJB has its own java:comp/env namespace. Since you have specified the resource-ref for your web component and not the EJB component, the java:comp/env namespace will be empty for the EJB and hence the lookup fails.

                    Just to verify this, you can lookup the datasource "java:comp/env/app-specific/datasource" directly in the init method of the startup servlet. I believe you should be able to successfully get the datasource.

                    If you want the datasource to be available at java:comp/env namespace of the EJB, then you will have to define a resource-ref through the ejb-jar.xml and jboss.xml for the EJB.

                      Thank you very much jaikiran, this is exactly what I was trying to do, but I had a hard time explaining it.

                      The reason why we use a different resource-name for the datasource in our EJB code than what is defined in the -ds file is because our application is customizable and need to be deploy using different databases for different clients. The way we did that is to define a bunch of different datasource JNDI in the -ds file (like app-specific/datasource) but map all of them to the same reference datasource in our code (app/datasource). That way our EJB code remains generic.

                      The explanation about Web environment vs EJB environment makes total sense, although this is not something I would expect to change from 4.X to 5.0 ;-)

                      I will try to add the missing EJB references this week and see if it works.

                      Thanks again for all the comments!

                        I verified this and it worked like you expected it.

                        I am going to try to add the references in the EJB context. This is not very simple because we don't currently have a ejb-jar.xml or jboss.xml file; we only use annotations to define our session beans. I can easily add those files, but I have to define every single EJB since they all access our database (and there are many of them). So it's kind of a pain. But I will work on that soon.

                        Thanks again.

                          I don't know how its working for you on JBoss-4.2.2. On my local setup, this does not work on 4.2.2 nor on 5.0, as expected.

                            Since you are using annotations, you need not create those ejb-jar.xml or jboss.xml. In your EJBs you can add this @Resources class level annotation:


                            @Resources( {
                             @Resource(type = DataSource.class, name = "app-specific/datasource", mappedName = "java:/app/datasource")
                             })
                            public class MyBean implements MyInterface {
                            


                            This is equivalent to having the resource-ref defined in the ejb-jar.xml and jboss.xml.
