I would like to run a stand-alone java program to add Layouts and Portlets into Layouts programmatically.

I did the following to successfully add the Layouts

// HttpPrincipal httpPrincipal = new HttpPrincipal("http://localhost:8080", "liferay.com.1", "test");
// LayoutServiceHttp.addLayout(httpPrincipal,,,,,,,,,);

There is a thread here mentioned function "addPortletId". I tried this function the same way as "addLayout", however, it didn't work. I got "BeanLocatorIsNull" Exception.

It seems easy to call addPortlet function in view.jsp, but I would like to run a stand-alone java program rather than triggering the function on webpage. I am not an expert on web development. I am looking forward to getting some advices here. Thanks in advance.
