Mac: org.apache.catalina.startup.bootstrap app appears in dock?

[Simon Twigger <si...@mcw.edu>]

Hi there,

Im using Tomcat 4.1.18 and Java 1.3.1 on a dual processor G4, 1.5GB RAM.

I'm using Tomcat to serve JSP and servlets and most of the time all is  
well. However, when one particular servlet is called that generates a  
variety of GIF images Tomcat starts another application that appears in  
the dock: org.apache.catalina.startup.bootstrap.

This is in itself Ok, tomcat goes about its business and the  
applications work fine. However, if I then log out, the new app closes  
down and the tomcat server stops. When someone else logs in, Tomcat is  
no longer running and so noone can use the JSP/servlet pages until  
someone with root access restarts Tomcat. This is very inconvenient  
when the app is installed on a clients machine!

Can anyone tell me what triggers the  
org.apache.catalina.startup.bootstrap to appear and how to prevent it  
from happening. If I could stop it appearing, it wouldnt close when the  
user logs out and hence Tomcat would keep running.

If it makes a difference,  Ive got Tomcat set to have 250Mb of RAM by  
adding

export CATALINA_OPTS=-Xmx250m

to the startup.sh script in the {TOMCAT_HOME}/bin/startup.sh script

The bootstrap app only appears in the dock when this servlet generates  
the images (using Acme GIF Encoder classes). Given that these Acme  
classes are in the /classes directory for the servlet application and  
the bootstrap app seems to have something to do with loading classes  
and keeping them from the system classpath (see the Tomcat docs:  
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/catalina/docs/api/org/ 
apache/catalina/startup/Bootstrap.html) Im wondering if I can fix this  
by moving these classes somewhere or Jar'ing them up and moving to the  
/lib directory...?

If anyone has any suggestions I would very much appreciate some help  
with this.

Cheers,

Simon,
