    Cannot locate PostgresDS

    thegiantsquid Newbie

      I have sucessfully configured a postgres installation:


      <local-tx-datasource>
      <jndi-name>PostgresDS</jndi-name>
      <connection-url>jdbc:postgresql://devsun:5432/test</connection-url>
      <driver-class>org.postgresql.Driver</driver-class>
      <user-name>xxx</user-name>
      xxx
      </local-tx-datasource>



      Yet, the following code:
      // cheat a little and pack the JNDI properties
      Properties jndiProps = new Properties();
      jndiProps.setProperty(
      "java.naming.factory.initial",
      "org.jnp.interfaces.NamingContextFactory");
      jndiProps.setProperty(
      "java.naming.provider.url",
      "jnp://localhost:1099");
      jndiProps.setProperty(
      "java.naming.factory.url.pkgs",
      "org.jboss.naming:org.jnp.interfaces");

      Context initial = new InitialContext(jndiProps);

      DataSource ds = (DataSource) initial.lookup("java:/PostgresDS");


      yields:
      javax.naming.NameNotFoundException: PostgresDS not bound
      at org.jnp.server.NamingServer.getBinding(NamingServer.java:495)
      at org.jnp.server.NamingServer.getBinding(NamingServer.java:503)

      at com.ieminc.met.client.JDBCClient.main(JDBCClient.java:38)

      I have successfully deployed entity beans using this configuration, yet I cannot lookup a Datasource...


      Any ideas?

          Also, the startup log yields this:


          14:28:49,009 INFO [PostgresDS] Bound connection factory for resource adapter for ConnectionManager 'jboss.jca:service=LocalTxCM,name=PostgresDS to JNDI name 'java:/PostgresDS'

            And....

            if I yank server\default\jnpserver.jar out of the runtime classpath, i get:

              Welp, apparently, I cannot remotely lookup DataSources, as I can only use the "java:/" prefix when I'm in the same VM, which I suppose, means I need to deploy this app as a stateless SessionBean.

              Thanks, I guess, to whomever read this.

                That's correct, and you're welcome ;-)
