    NotSerializableException with BasicDataSource in JNDI

    81103cac-5cd0-4c3b-844c-88c0208f0f90

      I am setting up a standalone JNDI and loading a Datasource to the JNDI. DataSource I use is: org.apache.commons.dbcp.BasicDataSource

      The JNDI is set up as follows

       

        String detectorHost = InetAddress.getLocalHost().getHostName();
        System.out.println("detectorHost: " + detectorHost);
        System.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
        final NamingBeanImpl namingInfo = new NamingBeanImpl();
        namingInfo.start();

        final Main JNDIServer = new Main();

        JNDIServer.setNamingInfo( namingInfo );
        JNDIServer.setPort( 5400 );
        JNDIServer.setBindAddress(InetAddress.getLocalHost().getHostName());
        JNDIServer.start();

        final Hashtable _properties = new Hashtable();
        _properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
        _properties.put(Context.PROVIDER_URL, "jnp://" + InetAddress.getLocalHost().getHostName() + ":5400");

        final Context _context = new InitialContext(_properties);
        _context.createSubcontext("jdbc");
        String JNDI_PATH = "jdbc" + "/" + "mydbname";
        _context.bind(JNDI_PATH, getDataSource());


      I get the following exception


      javax.naming.CommunicationException [Root exception is java.io.NotSerializableException: org.apache.commons.dbcp.BasicDataSource]

      I don't quite follow why I am getting a NotSerializableException exception, this is a local JNDI in the same JVM and not a remote JNDI. Not sure why this occurs.

      Can some one advise what is wrong here.
