running a webapp reload breaks happyaxis.jsp

[Jeff Barrett <JB...@sawyermedia.com>]

I've got tomcat 4.1.27, jdk1.3.1_09, axis 1.1 final running on a win2k machine with the sample axis webapp installed in %CATALINA_HOME%\webapps.  I can start up catalina just fine and hit happyaxis.jsp with no probs.  If I then go to tomcat's webapp manager and reload the app, returning to that same happyaxis.jsp gives me errors at it's inability to find certain jars.

Specifically it can't find the jars located under %CATALINA_HOME%\webapps\axis\lib.  According to the happyaxis.jsp page, jars containing java.* and javax.* packages need to be in %CATALINA_HOME%\common, which they are.  The things happyaxis.jsp can't find are: axis, commons-discovery, log4j, wsdl4j.  

Any ideas?


PS - As an interesting side note, this behavior does not occur if I run stop, followed by start in the manager.  Unfortunately this doesn't cut it for me.  According to some tests I ran, it doesn't look like stop/start successfully unloads the webapp classloader.

PPS - The relavent before and after output from happyaxis.jsp is below.
