Subject RE: Two hosts setup, jsp won't work!
Date Tue, 01 Jun 2004 18:11:26 GMT
Thanks for your advise.  I did what you said.  The jars have unique classes.  Also the exact
same application works on my other machine (exact jars and everything else), but the other
machine runs Red Hat 9 and Tomcat 4.X.X   and here I'm trying to install this app on Fedora
Core 1 and Tomcat 5.0.24
I commented out both hosts to run the app on localhost:8080 and it gave me the same error...
 I'm at a loss...
Any ideas?
Thanks for the help.

First things first -- if you're going to use multiple virtual hosts, you'd
do well to either 1/ use separate appBase dirs, or 2/ disable autoDeploy
and deployOnStartup for your <Host> elements.

Otherwise, each vhost will deploy both webapps when it starts.

Are all of the classes unique between the jars? (That is, are there any
classes defined in multiple jars?)  If not, things could get messy down the

To start debugging, you could disable the vhost for WebTest1 (just comment
it out) and focus on WebTest2.

Then, pare down the list of jarfiles in WebTest2/WEB-INF/lib.  Confirm that
each jar is indeed a valid file (a quick "jar -tf {file}" should do) and
that the required class, and every class on which it depends, is available
either in a JAR in WebTest2/WEB-INF/lib or a bare class in

No need to do this -- WEB-INF/classes will only load bare class files;
jarfiles must exist in WEB-INF/lib.

The dirs look OK.  If other JSPs compile without a problem, you can pretty
much narrow it down to a missing/rogue jarfile or class.

Probably not a permissions problem, but you probably don't want root
running the Tomcat process.  

Once you've solved  your immediate JSP problem, you may want to look into
commons-daemon/jsvc.  (This was discussed recently on the list; see the
archives for details.)
