Could I ask why you are working with jetspeed 1.6 rather than 2.0?

For now I suggest you preprocess the portlet.xml and web.xml to include 
the portlet-wrapping-serviets directly in your web.xml.

What is preventing you from using a  geronimo plan?  If you wish to  
avoid needing a geronimo plan for locating a resource-ref you need to 
make sure the resource-ref-name is identical to the 
connection-factory-name in a deployed datasource.  For instance, in a 
standard geronimo installation, a resource-ref-name of 
SystemDatasource, looking up "java:comp/env/SystemDataSource" will find 
the datasource deployed in the system-database-plan.xml.

I haven't looked at jetspeed autodeploy in about a year, so I'm not 
entirely sure how it works now.  As I recall the version I looked at 
dynamically generated a web.xml from the supplied web.xml and 
portlet.xml, then called something in tomcat to deploy the modified 
web.xml.

This is not really an appropriate architecture for geronimo IMO, at 
least for the jetty integration.  First of all, there is currently no 
autodeploy at all in geronimo, and if we implement one it will be a 
minor add-on input to the jsr-88 deployment system.

The way I imagine portlet deployment working is something like this:

-- portlet deployer gets access to the web app and determines that 
there is a portlet.xml
-- At some point in the web app ModuleBuilder, the portlet builder gets 
a chance to process the portlet.xml and add gbeans to the configuration 
representing the servlets wrapping the portlets.
-- these gbeans are started along with the other gbeans in the 
configuration.

This would work more or less directly for jetty.  IIUC the tomcat 
integration is still allowing the tomcat deployment code to process the 
web.xml itself.  Therefore a tomcat portlet deployer would probably 
have to modify the web.xml rather than configuring gbeans directly.  
However,  I think ejb web service deployment does not involve any 
web.xml processing, so it may be possible to do something analogous for 
portlets and configure them directly.

Thanks!  Please keep us informed of your progress and problems you may 
encounter.
