[xfire-user] problem invoking service

[JHunsaker]

I am receiving the following exception:

Exception in thread "main" org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: Error invoking 'com.bts.print.service.PrintService.startBatch(java.lang.String)'. Nested exception is java.lang.reflect.InvocationTargetException: null

        at com.bts.print.service.test.Test.main(Test.java:9)

The code looks like this:

        public long startBatch(String typeName) {
                Service serviceModel = new ObjectServiceFactory()
                                .create(PrintService.class);
                XFire xfire = XFireFactory.newInstance().getXFire();
                XFireProxyFactory factory = new XFireProxyFactory(xfire);
                PrintService printService = null;
                try {
                        printService = (PrintService) factory.create(serviceModel,
                                        serviceUrl);
                } catch (MalformedURLException e) {
                }
                long batchId = -1L;
                batchId = printService.startBatch(typeName);
                return batchId;
        }

How can I begin to trace this?
