Can't call local java class outside of context

[D]

Hi All, I'm having a problem at the moment trying to invoke methods in local
classes located outside the project containing the DynamicInvoker. As the
classpath attribute is currently not supportted in the WSIF classes, I
extended the WSIFPort_Java class to add a hack to allow specifying where the
class is located. Below is the WSIFPort_Java method I've overridden in my
own class.

public java.lang.Object getObjectReference() throws WSIFException {
        Trc.entry(this);
        Object objRef = null;
        boolean localClass = true;
        try{
         objRef = super.getObjectReference();
        }
        catch(WSIFException wEx){
         localClass = false;
         System.out.println("Could not find class in current work
environment, checking local drives");
        }


        if (!localClass) {
            JavaAddress address = null;

            try {
                ExtensibilityElement portExtension =
                    (ExtensibilityElement)
this.getPortModel().getExtensibilityElements().get(0);

                if (portExtension == null) {
                    throw new WSIFException("missing port extension");
                }

                address = (JavaAddress) portExtension;
                String classPath = address.getClassPath();
                if(classPath.indexOf("file://") < 0)
                 classPath = "file://" + classPath;
                URL[] classUrl = {new URL(classPath)};
                String className = address.getClassName();
                URLClassLoader urlClassLoader = new
URLClassLoader(classUrl);
                Class c =
Class.forName(address.getClassName(),true,urlClassLoader);
//                Class c = urlClassLoader.loadClass(className); produces
same class as above
                objRef = c.newInstance();
            } catch (Exception ex) {
             Trc.exception(ex);
                throw new WSIFException(
                    "Could not create object of class '" +
address.getClassName() + "'",
                    ex);
            }
        }
        System.out.println(objRef.toString());
        Trc.exit(objRef);
        return objRef;
    }

There are 2 possibilities when this method is called, either the class is
local to the project or if not it is in a different folder or drive.
When the class is not local the location of the class is obtained from the
classPath attribute in the WSDL file and a URLClassLoader class is
instantiated. The object I return from this looks the same as the object
returned when the super.getObjectReference() method is called, however, I
get an exception in the

operation.executeRequestResponseOperation(input, output, fault)

call in the DynamicInvoker if I use the object returned using the
URLClassLoader. This exception is below:

WSIF0005E: An error occurred when invoking the method 'getTestOutput'.

I'm at a bit of a loss as to why this happens and would appreciate any help
or suggestions.

Thanks as always in advance
