Dynamic processing by Catalina of webapp's context.xml fails using ./bin/startup.sh

           Summary: Dynamic processing by Catalina of webapp's context.xml
                    fails using ./bin/startup.sh
           Product: Tomcat 5
           Version: 5.0.27
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: cgay@agilecast.com


According to the documentation, the proper way to create application context is by including
a file 
named "context.xml" in the META-INF directory of a webapp.  

It appears that Tomcat 5.0.27 only recognizes such a context file when the war is deployed
using the 
Manager tool's "DEPLOY" feature.   When "DEPLOY" is used, Catalina properly recognizes the
context 
and dynamically creates $CATALINA_HOME/conf/Catalina/localhost/<appname>.xml   If Tomcat
is 
started with the same war file in the webapps dir, the context file is not found and a _directory_
is 
created at $CATALINA_HOME/conf/Catalina/localhost/<appname>.xml.

This bug is _related_ but not identical to BUG #29688.


Use Case to create bug
--------------------------
1. Stop Tomcat using  $CATALINA_HOME/bin/shutdown.sh. 
2. Make sure $CATALINA_HOME/conf/Catalina/localhost/<webapp>.xml is deleted.
3. Clear all references to the webapp  $CATALINA_HOME/webapps by deleting the dir <appname>
and 
the file <appname>.war
3. Clear all the logs in $CATALINA_HOME/logs
4. Place the webapp's WAR file in $CATALINA_HOME/webapps.  The webapp war has the following
basic 
structure:
    <appname>.war
         index.jsp
         /META-INF
              context.xml
         /WEB-INF
              web.xml
              /lib
              /classes
5. Start Tomcat by running  $CATALINA_HOME/bin/startup.sh
6. Navigate to the application's URL

Disclaimer:
---------------------------
I and my coworker spent 2 days debugging this.   We read all of the Tomcat 5 documentation,
the 
newsgroup bug reports, and reviewed all the outstanding Tomcat 5 bugs in bugzilla.  We tried
all 
manner of context configurations and locations.
