Catalina problem or Jspwiki: hard to say

It seems that I can get any other webapp to run in individual files (with a
".xml" extension)
unless it happens to be a jspwiki webapp.

I created two war files:
one contained the jsp-examples that comes with Tomcat.
the other contained a wiki1 that otherwise runs fine when deployed under
webapps (using the edited property file under WEBINF and the default policy
file)

I then undeployed the two older webapps (jsp-examples.war & wiki1.war) and
created two xml files:
jsp-examples.xml
wiki1.xml

Each file contains the following lines respectively:
<Context path="/jsp-examples" docBase="/home/claudia/wikis/jsp-examples.war"
debug="0" />
<Context path="/wiki1" docBase="/home/claudia/wikis/wiki1.war" debug="0" />


The jsp-examples works fine. The wiki1.war which still contains the edited
property file under WEBINF,
however,

  gives this error:
http://localhost:8080/wiki1/

*The requested resource (/wiki1/) is not available.
*
It is hard for me to diagnose this as a apache-tomcat-5.5.20 or Jspwiki
problem.
No errors from Catalina. No log messages. I am using ubuntu (linux),
apache-tomcat-5.5.20 and Jspwiki 2.4.104.
Have tried tons of variations of this for several days ..so I guess I won't
be able to share the same war file with different wikis :-(
Anyone else tried this?

Thx,
Claudia

I also read and understood the docs on the context container here:
