FacesServlet denies acces when using Web Services on Google App Engine - web-services

Question

I'm developing a sample application with Google App Engine over Java that uses Web Services.
Everything works well when I work in the local enviroment, the server service is deployed in my google account and the client is deployed in my local environment.
The problem comes when I deploy the application on Google App Engine and try to execute it. An exception occurs when the backing bean tries to create an instance of the server client:
This is the exception I get:
javax.el.ELException: /home.xhtml at line 20 and column 64 action="#{bergeData.obtenerListado}": java.lang.ExceptionInInitializerError
Caused by:
java.security.AccessControlException - access denied ("java.lang.RuntimePermission" "getClassLoader")

`
The trace of the exception starts in this line of code:
AutomovilServletClient clienteService = new AutomovilServletClient();
AutomovilServletClient has a constructor which initializes the API service:
public AutomovilServletClient() {
this.automovilAPI = new AutomovilServerAPIService().getAutomovilServerAPIPort();
}
First goes to the constructor of AutomovilServerAPIService:
#WebServiceClient(name = "AutomovilServerAPIService", targetNamespace = "http://server.beeva.com/", wsdlLocation = "http://1.XXXX.appspot.com/AutomovilServerAPIService.wsdl")
public class AutomovilServerAPIService
extends Service
{
private final static URL AUTOMOVILSERVERAPISERVICE_WSDL_LOCATION;
private final static Logger logger = Logger.getLogger(com.beeva.client.gen.AutomovilServerAPIService.class.getName());
static {
URL url = null;
try {
URL baseUrl;
baseUrl = com.beeva.client.gen.AutomovilServerAPIService.class.getResource(".");
url = new URL(baseUrl, "http://1.XXXX.appspot.com/AutomovilServerAPIService.wsdl");
} catch (MalformedURLException e) {
logger.warning("Failed to create URL for the wsdl Location: 'http://1.XXXX.appspot.com/AutomovilServerAPIService.wsdl', retrying as a local file");
logger.warning(e.getMessage());
}
AUTOMOVILSERVERAPISERVICE_WSDL_LOCATION = url;
}
public AutomovilServerAPIService() {
super(AUTOMOVILSERVERAPISERVICE_WSDL_LOCATION, new QName("http://server.beeva.com/", "AutomovilServerAPIService"));
}
}
In the method AutomovilServerAPIService() is where I lose track of the execution. I have checked the content of the constant AUTOMOVILSERVERAPISERVICE_WSDL_LOCATION and it's correct.
Anyone has an idea of why it happens when it is deployed up to Google App Engine?
Thanks in advance
UPDATE: Trying the SOAP example of Google Developers I have found that the problem comes with use of Java Server Faces Servlet. My project is a Google Web Application Project with JSF capabilities. So this line in the web.xml is what causes the problem:
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
However, I have no idea how to fix it :(
UPDATE 2:
SOLVED!! I have found that the problem is a incompatiblity of GAE with Apache MyFaces JSF-Core 2.0. When adding JSF Capabilities via properties/Project Facets, select JSF 2.0 (Mojarra 2.Z.X-FCS) instead of Apache MyFaces

Answer 1

I tried example at https://developers.google.com/appengine/articles/soap and it is working both locally and online.
The changes i made before online deployment were:
For Server application changed url in wsdl file
For client application changed url in SOAPService.java
I think second change you have already done.
Can you confirm whether you have updated WSDL file before deploying online?
<service name="TestSOAPService">
<port name="TestSOAPPort" binding="tns:TestSOAPPortBinding">
<soap:address location="**http://CHANGE_TO_ONLINEID.appspot.com**/testsoap"/>
</port>
</service>
