Calling Portal Application from Custom WD Application

Hi,

I'm developing a custom WD Application which has to call the already implemented ESS application such as Personal Information application and I'm struck with the following questions:

1. Do I have to reuse that particular ESS DC in my current DC?

2. IF I have reused ESS DC, how could I call that Personal Information IView from my WD Application?

Please suggest me.

Regards,

RN
