Hi,
if you want to use different instances of your application in a single servlet
engine, you have to make sure that the necessary classes, especially if they contain
static variables, are located in /WEB-INF/classes or /WEB-INF/lib. That you way you
can make sure that they are loaded by different classloaders (if the engine obeys to
the spec) and do not interfere. For classes with static variables this is essential.
The URL problem should be solved by simply calling getServletContext() or using
relative URLs in the whole application (probably even better).
Besides that I don't know what problem one could have...
Hope this helps,
