JAX-WS and Prefix '' is already bound to ''

[Marek Krokosinski]

Hello.

I have problem with my JAX-WS server and deployment it to tomcat 6. I used this tutorial http://java.dzone.com/articles/jax-ws-deployment-five-minute. I'm using JAX-WS 2.5, tomcat 6, jdk1.6. Any ideas? I'm trying to resolve my problem since 3 days ;x
Here are my classess and xmls:
Greeting.java

package juma.mohammad;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface Greeting {
	 @WebMethod String sayHello(String name);
}

GreetingImpl.java

package juma.mohammad;

import javax.jws.WebService;

@WebService(endpointInterface = "juma.mohammad.Greeting")
public class GreetingImpl implements Greeting {

	@Override
	public String sayHello(String name) {
		return "Hello, Welcom to jax-ws " + name;
	}

}

SayHello.java

package juma.mohammad.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(name = "sayHello")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "sayHello")
public class SayHello {

    @XmlElement(name = "arg0", namespace = "")
    private String arg0;

    /**
     * 
     * @return
     *     returns String
     */
    public String getArg0() {
        return this.arg0;
    }

    /**
     * 
     * @param arg0
     *     the value for the arg0 property
     */
    public void setArg0(String arg0) {
        this.arg0 = arg0;
    }

}

SayHelloResponse.java

package juma.mohammad.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(name = "sayHelloResponse")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "sayHelloResponse")
public class SayHelloResponse {
    @XmlElement(name = "return", namespace = "")
    private String _return;

    /**
     * 
     * @return
     *     returns String
     */
    public String getReturn() {
        return this._return;
    }

    /**
     * 
     * @param _return
     *     the value for the _return property
     */
    public void setReturn(String _return) {
        this._return = _return;
    }

}
