When I want to get the list of services in a Package, I will use below code

Java service -

i/p pipeline - package (string)
o/p pipeline - services (string list)

IDataCursor idatacursor = pipeline.getCursor();

        String s = IDataUtil.getString(idatacursor, "package");

        int i = s.lastIndexOf(File.separator) + 1;

        String s1 = s.substring(i);

        IData idata1 = IDataFactory.create();

        IDataCursor idatacursor1 = idata1.getCursor();

        IDataUtil.put(idatacursor1, "showServices", "true");

        IDataUtil.put(idatacursor1, "package", s1);

        IData idata2 = IDataFactory.create();

        String as[] = null;

        try

        {

            IData idata3 = Service.doInvoke("wm.server.packages.adminui", "packageInfo", idata1);

            IDataCursor idatacursor2 = idata3.getCursor();

            as = IDataUtil.getStringArray(idatacursor2, "services");

            idatacursor2.destroy();

        }

        catch(Exception exception) { }

        IDataUtil.put(idatacursor, "services", as);

        IDataUtil.put(idatacursor, "index", (new StringBuilder()).append("").append(s1).toString());

        idatacursor.destroy();

Runtime - Give the package name as the input. Output will be list of all services in that package.

hmmm... may be I can enhance above code, to use characters(%,*,?) in the package name? Yes, it will be handy.

cheers!
