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

[Gérald Fenoy]

Dear Matthias,
Thanks for your feedbacks.

Setting ZooWrapper for the service provider is correct.

The class file should be located in the same directory as zoo_loader.cgi as you try at the begining.
Indeed, the ZOO-Kernel should use this directory as default CLASSPATH.

I guess it won't imply any trouble but the PYTHONPATH you set sounds odd.
As for each environment variables, setting the CLASSPATH this way should work I guess. Nevertheless, can you confirm that the apache user get access to this directory and files located into this directory ? It is probably the cause of the issues.

It means that the ZOO-Kernel is using its directory as defaut CLASSPATH. So, you should copy your class file in this directory. The directory where the zoo_loader.cgi cgi script is located. If you do that, you don't have to modify the CLASSPATH using the [env] section.
