Tomcat Help

[Ryan Ollerenshaw]

I am trying to set up Tomcat 5 on Fedora Core 5 and everything iw
working find but i do not know how to set my classpath when using
tomcat below is a few things that i have tried.

I have found i can use the following code to print out the classpath
that my program is actaully using, the code is:

Get the System Classloader
        ClassLoader sysClassLoader = ClassLoader.getSystemClassLoader();

//Get the URLs
        URL[] urls = ((URLClassLoader)sysClassLoader).getURLs();

for(int i=0; i< urls.length; i++)
        {
           out.println(urls[i].getFile());
           out.println("<br>");
        }

and the classpath that is printed is:

/usr/java/j2sdk1.4.2_12/lib/tools.jar
/etc/tomcat5/bin/dist/commons-daemon.jar
/etc/tomcat5/bin/bootstrap.jar

But i am not sure where this is getting set, i do have the following
in my /tomcat5/bin/startup.sh

export CLASSPATH=./mapscript.jar:.:/etc/tomcat5/webapps/my_test/WEB-INF/classes

so why is this not my classpath at run time??

Tomcat does all kinds of weird things to the classpath.  Any jars your
webapp needs need to be in its WEB-INF/lib directory.

Yes i have already done this, no help, could it be that the eclipse
tomcat plugin is setting its own classpath somewhere?  I have added
the jar to window -> preferances -> java -> classpath. but maybe i am
missing somthing else. It just seems that the ./startup.sh script in
the  tomcat directory does not have any effect when i make changes to
it.
