How to access Portlets from Notes 8.5.1

Hi,

can anybody tell me which steps are necesary to access Portlets on a Websphere Portal Server 6.1 from Notes to use them in a composite application ?

Is there any tutorial available ?

I 've read that i need to install some expeditor Files but i don’t have any idea where i could find these files. A search on the Ibm sites didn’t help.

Thanks for any help.
