Subject: Skunkworks Project - Fun with WSRP
Date: Tue, 2 Nov 2004 17:31:24 -0500 (EST)
Folks,
You may have heard me speak of the NMI Grid Portal Project
( which is currently based on CHEF, but is
moving to uPortal + Sakai.
Beth Kirshner here at UM is taking the lead on this project here and has
been doing some work getting ready for the connection between uPortal and
Sakai using WSRP. My suggestion to OGCE was to do uPortal first and then
Sakai later via WSRP. OCGE is pre-releasing a preview edition of the
Gird-Based uportal at Supercomputing next week.
I attach two screenshots of uPortal and Sakai communicating via WSRP. The
first screenshot is a (very very simple) Sakai tool rendered within uPortal
and the same Sakai tool rendered in Sakai. The tool in both cases is
running on the Sakai server.
Beth has added WSRP4J to Sakai (multi-webapp makes this much easier) and
hooked up the WSRP producer API's.
Of course like any good skunk works project there is a bit of "not
completely general" code involved here, but it is encouraging to see the
basic "trans-continental railway" connected enough for one train to pass.
There is lots of work yet to do - passing single sign on between uPortal and
Sakai and then passing Grid credentials between uPortal and Sakai and then
and then and then...
So while there is still a lot of work to do, it feels good to see this
starting to come together.
/Chuck
