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

[Gérald Fenoy]

Dear Matthias, 
many thanks for you feedbacks.

The serviceProvider should mention the name of the class note the filename.
So in your case I guess the class defined in the file is named ZooWrapper so
you should set : 

   serviceProvider = ZooWrapper

Indeed, CLASSPATH can be set in the [env] section if needed. For instance, 
if you need to load/use specific jar files as you asked. So, you can specify the 
class name then use a specific CLASSPATH in the [env] section of your main
configuration file (main.cfg). Until the class name is found in the CLASSPATH
it should work. 

Note that the CLASSPATH should automatically be updated to add the directory 
where the ZOO-Kernel is located.

You are right, there is no specific section for Java Services implementation, we 
probably have to create a ticket for this task to be done. Nevertheless maybe you
can take a look at this : 
http://zoo-project.org/trac/wiki/ZooWebSite/ZooServices/Examples#Java

Even if it is similar to read the HelloJava.java source and and the HelloWorldJava.zcfg.

Hope to hear from you.
Best regards,
