At the moment my attempts and results are very confusing.
So I will try to describe my approach.
First, the Webservice Interface:
@WebService
public interface HelloWorld
{
String sayHi(@WebParam(name="text") String text);
}
The implementing Service:
@WebService(endpointInterface = "webservices.HelloWorld", serviceName =
"hello")
public class HelloWorldImplementation implements HelloWorld
{
@Override
public String sayHi(String text)
{
return "waaaaazzzzuuuuuupp?! you said: " + text;
}
}
The Servlet which shall control the Transport:
public class HelloWorldServlet extends CXFNonSpringServlet implements
Servlet
{
@Override
public void loadBus(ServletConfig servletConfig) throws
ServletException
{
super.loadBus(servletConfig);
Bus bus = getBus();
BusFactory.setDefaultBus(bus);
HelloWorldImplementation service = new
HelloWorldImplementation();
Endpoint.publish("/testService", service);
}
}
An finally the Server with its publishing mechanism:
public class JettyServletLauncher
{
public static void main(String args[])
{
// String busFactory =
System.getProperty(BusFactory.BUS_FACTORY_PROPERTY_NAME);
System.setProperty(BusFactory.BUS_FACTORY_PROPERTY_NAME,
"org.apache.cxf.bus.CXFBusFactory");
Server server = new Server(8080);
Context root = new Context(server, "/", Context.SESSIONS);
HelloWorldServlet nonSpringServlet = new HelloWorldServlet();
root.addServlet(new ServletHolder(nonSpringServlet), "/*");
try
{
server.start();
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
Now to my masses of questions:
1. If I get it right, CXF detects if a jetty/ webserver instance is
already bound. In my case, I start
jetty @ port:8080 with its root as context path. From my experiences I
am used to bin the soap service
url as relative path which is added to the jetty's context path. In my
example /testService, so that the
services should be bound to http://localhost:8080/testService?wsdl, the
service itself is mapped to the
name "hello".
This raises the exception I mentioned before, where you detected the
problem of the wrong protocol:
an AnnotationVisitor
([EMAIL PROTECTED]) raised an
exception on element
public void
org.apache.cxf.transport.jms.JMSTransportFactory.setBus(org.apache.cxf.Bus)
You suggest to control the URIs again which are published through the
endpoint. But why should I add the
protocol within the Endpoint.publish method?
But if I do so, it seems that http-transport is chosen:
Endpoint.publish("http://localhost:8080/testService";, service);
This URI seems redundant to me, because the port and the root path is
already defined by the jetty configuration.
But the problem isn't solved then: accessing localhost:8080 gives me an
hyperlink:
{http://webservices/}HelloWorldImplementationPort
which references:
http://localhost:8080/testService?wsdl - resulting in a message "No
service was found."
I am especially wondering how (name of) the hyperlink is created ..
just tried another thing:
Endpoint.publish("http://localhost/testService";, service); // notice: no
port
This works (I get a wsdl)! But now an IllegalStateException from the
servlet is thrown ..
java.lang.IllegalStateException: STREAM
at org.mortbay.jetty.Response.getWriter(Response.java:585)
2. As comparison I used the internally started jetty, the main code
reduces then to this:
CXFNonSpringServlet servlet = new CXFNonSpringServlet();
BusFactory.setDefaultBus(servlet.getBus());
HelloWorldImplementation service = new HelloWorldImplementation();
Endpoint.publish("http://localhost:8080/testService";, service);
JOptionPane.showMessageDialog(null, "Stop Server");
This works pretty good, the URI http://localhost:8080/testService?wsdl
creates a valid wsdl.
3. My main problems seems to be the choice of the transport protocol,
where JMS is used. Is this configuration
only dependend on the URI I use by the endpoint publishing?
4. There is one point within the use of the framework, I do not
understand:
The Endpoint class is from the JDK. Enpoint.publish() uses the
Provider-factory to get EndpointImpl for publishing
the service. Where and at which point is the Endpoint-Implementation of
CXF injected?
Many thanks in advance for digging through my questions!

Hi Serethos,
You are picking up JMS transport and not servlet. Make sure you have
proper URI in your wsdl service and endpoint.publish() call.

Hello!
I need to get the Servlet Transport of CXF and Jetty to work together
but
have several problems with it.
Searching within forums, mailing lists and the inet there is often
mentioned
the complete source the to code snippet example of the user doc
(http://cwiki.apache.org/CXF20DOC/servlet-transport.html).
The problem ist that the links to the cxf repository are always dead
(like
this one:
https://svn.apache.org/repos/asf/incubator/cxf/trunk/systests/src/test/java/org/apache/cxf/systest/servlet/NoSpringServletServer.java
)
Is there any source to get all classes of the example so that I can
test
it
and exclude an error of mine?
As addition I want to attach my StackStrace of the error. Perhaps
someone
could give me a hint, what the problem could be (and what an
'AnnotationVisitor' is)
an AnnotationVisitor
([EMAIL PROTECTED]) raised an
