hello

im developing a portlet with very special requirements, and the CMS service seems to adequate very well to my needs, but i cant find information in deep about the functionality of that service or how to use it properly. i need to know the objects that execute command returns , and that kind of things. the only way i have to know about the service is looking at the source code of the implementation.

there is any documentation about the services that portal offer me?

thanks in advance
