[ZOO-Discuss] Java based Service: <ows:ExceptionText>can't find class ZooWrapper.class</ows:ExceptionText>

[Matthias Lendholt]

Dear Gérald,
thanks for your quick response. Unfortunately it's still not working.

Ok. I tested both versions but both are not working.

I added this section to the main.cfg but I'm not sure if this is correct.

[env]
CLASSPATH=/home/dews/zoo/zoo-project/javaservices/
PYTHONPATH=/usr/bin/python

(the class ZooWrapper.class is located in the javaservices directory)

Could you rephrase this? I'm not sure whether I understood you 
correctly. Do I have to point the classpath to the zoo-kernel directory?


Thanks for your help!

Matthias
