Hi guys,
I used wsprovide in the bin folder of jboss as 4.2.2GA to generate wsdl and java files.
the class is :

package echo;

@javax.jws.WebService
public class Echo
{
 public String echo(String input)
 {
 return input;
 }
}

the command line : wsprovide.bat -ktw echo.Echo

the generated files have a wsdl and two java files.
A java file is : EchoResponse.java

package echo.jaxws;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;

@XmlRootElement(namespace = "http://echo/", name = "echoResponse")
@XmlType(namespace = "http://echo/", name = "echoResponse")
@XmlAccessorType(XmlAccessType.FIELD)
public class EchoResponse {

 @XmlElement(namespace = "", name = "return")
 private String return;

 public String getReturn() {
 return this.return;
 }

 public void setReturn(String return) {
 this.return = return;
 }

}

the return is key of java, but in the java file , return is used to the name of a variable. This is big issue.
