jars on classpath within webservice?
Hi. I've created a web service using apache axis. I am having a problem getting my external classes on the classpath of my web service.
import com.mycompany.MyClass
publicclass MyService{
static{
MyClass.initialize();
}
public String myServiceMethod(){
...
...
}
}
When i deploy on weblogic 9.2 i get:
weblogic.application.ModuleException: [HTTP:101216]Servlet:"AxisServlet" failed to preload on startup in Web application:"mywar.war".

I believe the error is occurring when Axis loads the service class and the static block is executed. ie - <clinit>.
MyClass lives in a packaged jar - myjar.jar. How do I get myjar.jar on the runtime classpath of MyService?
I've tried placing myjar.jar in the WEB-INF/lib folder of the axis war, as well as packaging it in the .aar of MyService
Thanks!
