Doesn't seem to do anything except crash on Tomcat 4.1.12

I copied the library files into the common directory of tomcat and  
dropped this web application into the webapps directory and now  
everytime it runs I get:


http://localhost:8080/pixory/ 
pxapplication?service=page&context=AlbumBrowser
