Problem

In JAX-WS development, when following service endpoint is deploying,

File : HelloWorld.java

package com.mkyong.ws;
//Service Endpoint Interface
@WebService
public interface HelloWorld{
 
	@WebMethod String getHelloWorldAsString();
}

File : HelloWorldImpl.java

//Service Implementation
package com.mkyong.ws;
@WebService(endpointInterface = "com.mkyong.ws.HelloWorld")
public class HelloWorldImpl implements HelloWorld{
 
	@Override
	public String getHelloWorldAsString() {
		//...
	}
 
}

It hits following error message immediately?

Exception in thread "main" com.sun.xml.internal.ws.model.RuntimeModelerException: 
	runtime modeler error: 
 
        Wrapper class com.mkyong.ws.jaxws.GetHelloWorldAsString is not found. 
        Have you run APT to generate them?
 
	at com.sun.xml.internal.ws.model.RuntimeModeler.getClass(RuntimeModeler.java:256)
	//...

Solution

The service endpoint interface is not annotated with any @SOAPBinding, so, it uses the default document style to publish it. For human readability, you can rewrite it as following :

//Service Endpoint Interface
@WebService
@SOAPBinding(style = Style.DOCUMENT, use=Use.LITERAL)
public interface HelloWorld{
 
	@WebMethod String getHelloWorldAsString();
}

In document style, you need to use “wsgen” tool to generate all the necessary JAX-WS portable artifacts (mapping classes, wsdl or xsd schema) for the service publication.

wsgen command

The wsgen command is required to read the service endpoint implementation class :

wsgen -keep -cp . com.mkyong.ws.HelloWorldImpl

It generates two classes for a single getHelloWorldAsString() method, under package.jaxws folder.

  1. GetHelloWorldAsString.java
  2. GetHelloWorldAsStringResponse.java

Copy those classes to correct folder, in this case, it’s “com.mkyong.ws.jaxws“. Try publish it again.
