Custom Task UI - remote location

Hi there,

i'm using Netweaver BPM 7.3 EHP1 and try my first steps with BPM.

After completing the "MyNameAge"-Tutorial vom SCN and creating my own aproval-process i want to use custom user interfaces.

And here is my Question:

Is it also possible, to refer to a location on a different host? So i want to enter a absolute path instead of a relative path.

I like to do so, because we are using a IBM Websphere Portal for our Employee-Portal and i want the BPM to interact with that portal.

How would you do that? Any ideas?

Best regards,

Patrick

P.S: Is there any information (e.g. Tutorial) about creating custom UIs and how to access process data from context?
