Restarting Tomcat causes application to be displayed across all instances
Currently, we have a few three development instances of the "same"
application being run - webapps/A, webapps/B, and webapps/C. By same
I mean the same application, although each instance is usually a bit
different, as the developers work on their individual instance. The
problem we are facing is that when a user restarts Tomcat, their Java
code (and not their jsp or html code) is displayed on their web
instance as well as all other web instances. So, for example, if
user A restarts Tomcat, their Java code is seen also on the web
instances of user B and user C. It is important to note that the
actual code is not copied over to each of the users directory when a
restart occurs, yet the code is viewed across all instances. Anyone
have any idea why this behavior could be taking place? I recently
created a Listener class to precompute a few variables. This may or
may not be related (don't think it is). Thanks.

Tomcat does not explicitely use any specific classpath outside of it's
own. It even ignores the system set CLASSPATH variable. Check your
config settings and webapp for references to ~/cvs/fable/* directory.

Re: Restarting Tomcat causes application to be displayed across all instances
Posted by Ryan O'Hara <oh...@genome.chop.edu>.
I think I found a promising lead to what is going wrong here. The
FABLE application is
reading as if the CLASSPATH is set to ~/cvs/fable/web/info/ instead
of /usr/local/tomcat/
webapps/fable(_[user])/WEB_INF/classes/info. I found this out by
doing the following:
1. make install_dev.
2. rm /usr/local/tomcat/webapps/fable_ohara/WEB-INF/classes/info/
MedlineIndexSearcher.class
3. Tomcat restart
4. Lucene still worked on http://159.14.214.190/fable/ohara.
5. rm /usr/local/tomcat/webapps/fable & fable_darcy/WEB-INF/classes/
info/
MedlineIndexSearcher.class
6. Tomcat restart
7. Lucene still worked on http://159.14.214.190/fable/ohara.
8. rm ~/cvs/fable/web/info/MedlineIndexSearcher.class
9. Tomcat restart
10. Lucene did not work on http://159.14.214.190/fable/ohara.
So, from this, I believe that somewhere (whether it be in the
Makefile, the Tomcat restart
scripts, or somewhere else) the CLASSPATH is being set to ~/cvs/fable/
web/info rather than
/usr/local/tomcat/webapps/fable(_[user])/WEB-INF/classes/info. Now,
if I can only find
where this is happening.. Anyone have any ideas? Thanks so much.

Unfortunately, the startup script doesn't set the classpath and the
classes are not in the shared folders. Any other ideas? I am
currently digging..
Thanks again,

could be several reasons, one common one is that somewhere in your
restart script, you are setting the classpath manually to include the
classes.
another would be that your classes are in shared/classes or shared/lib
if not, you'd need to dig deeper.
