[las_users] Error 500 in newly installed LAS

[Bjørge Solli <bjorge.solli@xxxxxxxx>]

Hi I try to get a new copy of LAS up on a testserver. The testserver 
already run tomcat so I told LAS to use this instead of the one bundled. 
When I open http://testserver.com/las/servlets/dataset I get a 500 error:

#########

HTTP Status 500 -

Does anyone know what causes this error? It seems to me there is 
something wrong with the CLASSPATH (maybe caused by me using my existing 
tomcat instead of the bundled one?) I don't know how to set the 
classpath for servlets in tomcat5 but I did try this:
/usr/share/tomcat5/server/classes$ ln -s \ 
/usr/share/tomcat5/webapps/las/WEB-INF/classes/gov

But no sigar (yes, I restarted tomcat).

Any help appreciated.
