Hi,

I finally put my server classes into a jar file and deployed my services.
But whereever I put the jar (common/lib, lib, webapps/soap/WEB-INF/lib), he
cannot find my service. I even tried to alter startup.bat to include the jar
to the classpath, but I didn't change anything:

     [java] ] [FaultEntries=]
     [java] [Attributes={}] [faultCode=SOAP-ENV:Server.BadTargetObjectURI]
[faultString=Unable to resolve target object:
de.copark.services.TimeService] [faultActorURI=/soap/servlet/rpcrouter]
[DetailEntries=
     [java] [(0)=<stackTrace>java.lang.ClassNotFoundException:
de.copark.services.TimeService
     [java]     at
org.apache.catalina.loader.WebappClassLoader.loadClass(Webapp
ClassLoader.java:1394)
     [java]     at
org.apache.catalina.loader.WebappClassLoader.loadClass(Webapp
ClassLoader.java:1243)
     [java]     at
java.lang.ClassLoader.loadClassInternal(ClassLoader.java:322)
[...]

When I unpack the jar and put them to /common/classes, everything works
fine.

What can I do?

TIA,
Alexander
