Invoke webservice from webservice

Question

Hi All,
I am a newbie of using JDeveloper and I have a few questions about web service. The call flow is shown as below:
Caller(Machine C) -> web service (WS_B)(Machine B) -> web service(WS_A) (Machine A)
In Machine A :
I have deployed the web service called WS_A
In Machine B :
I have created a proxy service that points to the wsdl of WS_A. Also, I have created a webservice called WS_B that invokes the proxy service so that WS_B
can communicate with WS_A
When I check the webservice (WS_B) in the browser, it always says that "oracle.classloader.util.AnnotatedNoClassDefFoundError" . Thanks a lot.
Best regards,
David

Hi David,
If you are using JDeveloper to assemble your applications, and you have used the embedded version of oc4j, you may want to double check that all your bean have been included in the application module.
Sometime the embedded version will be working, because the .class files are in the classpath used to execute the application, while they are not found in the context of the application, once deployed on a remote container.
Check the list of classes included in your .ear. Select the node "WebServices.deploy" in the "resources" node of your project, and using right-click on the selection, select the Properties options. Under "Files Groups - WEB-INF/Classes - Filters", make sure all the classes have been selected.
Hope it helps,
