Please define "mess."  There are six jars (two of which are optional) 
that are copied to the shared/lib directory.  Not a single one of these 
should conflict with any other jars since they are all part of the 
Jetspeed project.  The only other modification is copying the 
jetspeed.xml to con/Catalina/local host, which defines the DS we use for 
our registry.  The only other thing I can think of is in Tomcat 5.x 
there was a modification to JAAS that breaks any other app trying to use 
their own JAAS implementation, so in this case we copy so patched 
classes to  server/classes to fix this.

The base build of Jetspeed 2 installs example portlets.  If you do not 
want a portlet, delete its application war from WEB-INF/deploy and it 
will be undeployed from Jetspeed 2 AND Tomcat.

All portlet applications MUST also be available as web applications, 
this is a requirement of the JSR-168 hence the reason for each portlet 
application also being a deployed as web application.  I think you 
should read the spec, especially PLT 3.1 and more specifically PLT 3.2 
which says a portlet container environment must fully support the 
Servlet 2.3 spec.  You should really do more research before you start 
criticizing a project.  Building an application server that lives inside 
another is no easy task, multiply that by our goal of being able to run 
Jetspeed 2 inside any servlet container.  This is why J2 is relatively 
more complicated when compared to J1.

This is probably due the failure to deploy the multicolumn portlet.  I 
will need to install tomcat 5.0.28 to see if it is a version conflict or 
just an issue with your specific environment.

The testsuite portlets are not installed by default.  You need to 
download and deploy them separately.

Just click the logout link in the login portlet.
