Description

Description:
If you have a Java class in your application or a Java shared module which calls a method from a third party library, the method invocation works fine in Studio. But when you install the application in Admin, it fails with ClassNotFoundException, with regard to classes present in the third party library.




Resolution

For the Java code to lookup the third party classes at runtime, set ContextClassLoader as follows: 

    ClassLoader cl = null;

    cl = Thread.currentThread().getContextClassLoader();
    try
    {
      Thread.currentThread().setContextClassLoader(getClass().getClassLoader());

 .....Your Java Code calling the third party library.....

    } finally {
      Thread.currentThread().setContextClassLoader(cl);
    }

There is a sample shipped with product showing the usecase : Interoperability of Using JAX-WS Client to Invoke Service  (tibco.bw.sample.binding.soap.http.JAXWSInterop).
