WSRP is an open standard proposed by OASIS for several years. The spec now is sponsored by a number of
big names like IBM and BEA. There are currently two active implementation of the spec. One is wsrp4j from
Apache foundation (still a incubator project, been developed since 2002). The other one is a subproject of
dev.java.net Open-Portal.
I have been exposed and done lot of development on the Apache's wsrp4j project. Thus, in this guide I will
mainly discuss wsrp4j implementation.
At this point, wsrp4j project is still under heavy development and re-construction. It is almost impossible
to get the trunk snapshot in the project repository and make it work without pulling all your hair out to figure
out how to set it up properly. This mostly caused by the lack of documentation and support from its developers.
Still, there is a stable (enough) revision which we can use to make a perfect wsrp4j environment.
The wsrp4j revison I use here is 440430 along with pluto portal 1.0.1 release for setting up a producer.
Jetspeed 2.1 (latest version currently) will be used as a container for wsrp4j consumer (wsrp4j-proxyportlet).
Of course, you can use pluto to setup wsrp4j consumer as well. But that is very easy to do.
Plus, pluto portal doesn't provide a lot of bell and whistle in the GUI side as Jetspeed portal does.
