SOAP on Google AppEngine

Question

I'm trying to develop a Java SOAP client in GAE. It is working in development(localhost) not on production(appspot). * No jar files are added in build path.

Exception:

com.sun.xml.bind.v2.runtime.reflect.Accessor$FieldReflection <init>: Unable to make javax.xml.ws.wsaddressing.W3CEndpointReference.address accessible.
java.lang.SecurityException: java.lang.IllegalAccessException: Reflection is not allowed on private javax.xml.ws.wsaddressing.W3CEndpointReference$Address javax.xml.ws.wsaddressing.W3CEndpointReference.address

ApiServiceService.java:

import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;

public class ApiServiceService extends Service {
    public ApiServiceService() {
     /*ApiServiceService.java:51*/   super(new URL("http://demowebsit.com/api?wsdl"), new QName("http://demowebsit.com/", "ApiServiceService"));
    }
}

Most of developers are facing the same issue when they deploy to production:

but in my case I'm not using any JARS apart from JRE.

Answer 1

After digging hole day i came to know gae found some whitelist class inside jax-ws package.

Reason :

javax.xml.ws.Service calls internally javax.xml.ws.spi.Provider.provide() method. In that it will create a Provider variable from FactoryFinder using com.sun.xml.internal.ws.spi.ProviderImpl class. But in gae ProviderImpl is not white listed so we can't able to create webService client using jax-ws.

Solution:

Apache Axis is using jaxrpc and it is compatible with gae. Generate WebService from wsdl using apache axis will solve this problem.
