unable to call a custom Java method from an Oracle Web Center Content Service

Hi Team,

I need to create a custom component in UCM which call a custom Java method from an Oracle Web Center Content Service. I'm following the steps provided in the guide for customizing the component  but I'm unable to call this custom component if this Custom Java Method internally using the RIDC API to call the Third Party WebService.

Method:

    public void greet() {

        try {

            String user = m_binder.getAllowMissing("dUser");

            m_binder.putLocal("StatusMessage", "Welcome user: " + user);

            UCM wccService = new UCM();

            m_binder.putLocal("StatusMessage", "Created UCM Class Instance");

            IdcClient idcClient = wccService.getUCMConnection("idc://nlwowcrvd03.mtn.co.za:4444");

            m_binder.putLocal("StatusMessage", "Got Client Connection");
