David,

Will this architecture persist in Jetspeed 2? Judging from discussions
I've read on this list I believe it won't. If not, could you describe the
differences using the same format as you did below?


J2 doesn't rely on Turbine.
J2 has its own servlet.
However J2 has a pipeline architecture, and does not use modules.
The request runs thru the pipeline where different Jetspeed portal components can plug in to the pipeline and perform some kind of processing.


http://cvs.apache.org/viewcvs/jakarta-jetspeed-2/portal/src/webapp/WEB- INF/conf/jetspeed-pipeline.xml?rev=1.3&content-type=text/vnd.viewcvs- markup

Probably the most significant changes in J2 are:
1. compliant with the Java Portlet Spec
2. Separates Portlet applications from the portal

#2 is very important to the architecture, since we are separating the concerns of the portal and the portlet application, cleaning up the system architecture significantly
