perfsonar development work

[Piotr Pikusa <>]

I don't know if simple linking /webapps/geant2-java-sql-ma to your code 
would work and make all libs visible to your classes. Notice that 
packages with classes are in 
/usr/share/tomcat5.5/webapps/geant2-java-sql-ma/WEB-INF/classes 
directory. Try copy your new and changed classes to proper directories 
and don't link anything. And copy all new built jars (ie. 
perfsonar-base) to  webapps/geant2-java-sql-ma/WEB-INF/lib .

To sum up. Don't link anything - just copy all files from yout build dir 
to proper directories in webapps directory. Remember that changing 
anything in code you touch many dependencies.

But it's nice to hear that you want develop new functionality, could you 
tell something more about it?

Cheers
