Can't locate custom tag library

[Bob Law]

I've been developing an application using tomcat and apache for a few months, and things are working great.  I have encountered a problem when I move my code to a machine behind a firewall.  When I initially installed it, things worked fine, but the last few weeks they haven't worked at all.  When I try to load a page that uses a custom tag, I am told that it is unable to open the custom tag library.  I also am told that the network is not reachable.  Everything is on the same box.  I know that the company's network is extremely tight (it is a bank) and they frequently change the settings.  Is there any way to have tomcat read the file on the local machine?  It all works on my machine at home, just not on the machines at work.  I am running Linux.   Thanks, Bob Law [EMAIL PROTECTED]
