如何从WSDL生成Web服务

Question

I know this question has been asked a few times, but I checked the stackoverflow history/questions and it does not quite answer what I am trying to do. I have a WSDL. I want to generate a web service for that WSDL. I know that I have to manually write something, but that's the part I need help.

I have a WSDL. I save it in /home/username/java/ws/wsdl/test.wsdl. I also have an xsd at /home/username/java/ws/wsdl/test.xsd used by the aforementioned WSDL.

I generate the server stubs for this like so:

[/home/username/java/ws/wsdl/] $ wsimport -p com.uptimeservice.ws -d build/classes -s src wsdl/test.wsdl

Now, I need an implementor. I create one like so under /home/username/java/ws/src/WsImpl.java:

package com.uptimeservice;  

import javax.jws.WebService;  

import com.uptimeservice.ws.*;  

@WebService(name = "UptimeService",
        targetNamespace = "test",  
    serviceName = "UptimeService",  
    portName = "UptimeServiceSOAP",  
    endpointInterface = "com.uptimeservice.ws.UptimeService",
    wsdlLocation = "/home/username/java/ws/wsdl/test.wsdl")  
public class WsImpl implements UptimeService {  

@Override
public UptimeResponseType uptimeRequest(UptimeRequestType msg) {  
    UptimeResponseType resp = null;
        return resp;  
    }  
}  

I compile it like so: [/home/username/java/ws/src/] $ javac -classpath /home/username/java/ws/build/classes/:. com/uptimeservice/WsImpl.java

Then when I try to deploy the service, like so: /home/username/java/ws/src/] $ java -classpath /home/username/java/ws/build/classes/:. com/uptimeservice/WsImpl

I get the error: Exception in thread "main" java.lang.NoSuchMethodError: main

My guess is that this is something very trivial, but I am not a Java person.

Any help is appreciated.

Thanks!

Generally a webservice will be installed on a java web server, such as Tomcat, Jboss, Jetty, Websphere, in a war file.

You are trying to run it manually, as a standalone application, and all standalone applications need a main function called main , just as C or C#, for example.

So, how are you actually going to deploy this, on a webserver or as a standalone application?

If you do it as a standalone application then you will need an embedded http server, btw.
