Re: ClientFactoryBean AbstractMethodError

Hi ,
Can you check xercesImpl-2.8.1.jar is in the class path of your test with JUnit? 
I can find the method

org.apache.xerces.dom.DocumentImpl.getInputEncoding() in that jar.

hanks. That doesn't really explain, to me, why the server starts up
fine when deployed but fails with the error shown when run in a JUnit
test. The demo is able to create a service in JUnit without problem.
In this particular JUnit, rather than relying on Spring configuration,
I was attempting to create the server myself using the following code:

private Server createRestServer(SessionFactory sessionFactory) {
        MyServiceImpl service = new MyServiceImpl();
        service.setSessionFactory(sessionFactory);

        JaxWsServerFactoryBean sf = new JaxWsServerFactoryBean();
        sf.setServiceClass(MyServiceInterface.class);
        sf.setBindingId(HttpBindingFactory.HTTP_BINDING_ID);
        sf.setAddress("http://localhost:8080/rest/";);
        sf.getServiceFactory().setInvoker(new BeanInvoker(service));
        sf.getServiceFactory().setWrapped(true);

        return sf.create();
}

This is almost exactly the same as the server code from the demo - the
code that works. However, in my example I receive the stack trace from
above on the sf.create() method.

I probabaly should remove JAX-WS style client codes from restful_http_binding 
demo, as it constantly causes confusions. In theory, JAX-WS style client APIs 
should work with RESTful services that published using CXF HTTP binding, as 
this is symmetric to what the server side has to do to marshal/unmarshal 
request/response. But in reality, this does not work because a). This JAX-WS 
style client APIs support is not completed yet. b). I don't think there will be 
much value added by supporting JAX-WS style client APIs. This JAX-WS style 
client APIs wont work without a WSDL, most RESTful services wont have a WSDL. 
More comments about client side REST API support can be found in [1].

Subject: ClientFactoryBean AbstractMethodError


I have been trying to get a REST service up and running. I believe the
server is up. However, creating the client is problematic. Using the
following code borrowed from the bundled rest sample:

JaxWsProxyFactoryBean sf = new JaxWsProxyFactoryBean();
sf.setServiceClass(MyServiceInterface.class);

// Turn off wrapped mode to make our xml prettier
sf.getServiceFactory().setWrapped(false);

// Use the HTTP Binding which understands the Java Rest Annotations
sf.getClientFactoryBean().setBindingId(HttpBindingFactory.HTTP

_BINDING_ID);

sf.setAddress("http://localhost:8080/rest/";);
this.service = (MyServiceInterface) sf.create();


I receive the following exception:

I read a post regarding a similar error due to the XmlSchema version.
However, after checking, I do have the 1.3.2 version specified in that
post
(http://www.nabble.com/wsdl2java-problem-tf4651922.html#a13290874).

Anyone have any other ideas?

Thanks.
