          i mean to say why I am unable to connect it from "myclient"

            Why dont you attach your 'ejb-jar.xml' and the part of client code, which is doing the lookup. That may help.

              Is there any need to edit ejb-jar zml for data source ?
              Because I have added mysql-service xml and added application policy name MySqlDB in login-config.xml.

                Is there any need to ejb-jar.xml?In case of Datasource?
                I have added mysql-service.xml in my deploy directory.

                    Oh! So you are not using ejb. You just want to use a DataSource from a client java program (that is may be within or outside jboss).

                    If that is the case, First I will suggest you see your JNDI Tree (using JndiView MBEAN available from http://localhost:8080/jmx-console).

                    Use the method list() or listXml() to see all the bindings done, and see what is the exact path ...in ur case u assume it is :

                    MySqlDS

                    If it is in 'Java' Namespace, I think you can use it only from within Jboss. You can do a lookup with

                    Context rootCtx = getInitialContext();
                    DataSource ds = (DataSource) rootCtx.lookup("java:/MySqlDS");


                    If it is in global jndi namespace, then you can do lookup from client outside jboss env.

                    DataSource ds = (DataSource) rootCtx.lookup("MySqlDS");

                    Hope this helps.

                      this is what I get from my
                      http://localhost:8080/jmx-console/index.jsp

                      jboss.jca
                      name=JBoss LocalTransaction JDBC Wrapper,service=RARDeployment
                      name=JMS Adapter,service=RARDeployment
                      name=Minerva JDBC XATransaction ResourceAdapter,service=RARDeployment
                      name=MySqlDS,service=LocalTxCM
                      name=MySqlDS,service=LocalTxDS
                      name=MySqlDS,service=LocalTxPool
                      name=hsqldbDS,service=LocalTxCM
                      name=hsqldbDS,service=LocalTxDS
                      name=hsqldbDS,service=LocalTxPool
                      name=jmsra,service=XaTxCM
                      name=jmsra,service=XaTxDS
                      name=jmsra,service=XaTxPool
                      service=CachedConnectionManager
                      service=RARDeployer

                      It clearly shows that MySqlDS is bound

                      Even if I am unable to get it from my client by the same name 'MySqlDS'.

                      Is there any problem of classpath or something ?

                        This is fine. But sometime, you want to see whether this is bound to which jndi name in "java:" namespace. For that you have to run JndiView MBean (which u can see in the jmx-console.


                        Also, you did not mentioned, from where you are running the client? are you running it from outside the Jboss?? or from within the jboss?? I have tested from within jboss like, jsp, session bean, etc. and it works fine.
