perfsonar development work

[Piotr Pikusa <>]

Hi André!

As you probably know, java.lang.NoClassDefFoundError: 
ServletContextListener may be caused for many reasons. Why don't you try 
to download tomcat5.5 and run it in different port? If everything would 
by ok with it stop tomcat, build your project and copy WAR file to 
webapps of new tomcat and run tomcat one more time observing logs. Of 
course service won't work because of lack of eXist and SQL connection 
but it should start and show web admin page. This little test tell us 
more about what can be wrong.

Cheers
Piotr Pikusa
