Spring Web Service - Echo example

[Sam Gehouse]

Any adviice will be appreciated. I looked at the documentation, downloaded the sample code. Unable to get the WSDL published. This is what I did:

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee">

<display-name>Echo Web Service Application</display-name>

<servlet>
<servlet-name>spring-ws</servlet-name>
<servlet-class>org.springframework.ws.transport.http.MessageDispatcherServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>spring-ws</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>

</web-app>

WEB-INF\spring-ws-servlet.xml

       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

	<property name="locationUri" value="http://localhost:9080/echoservice/"/>
	</bean>
	</property>
</bean>
</beans>

package echo.service;

public interface EchoService {
	public String echo(java.lang.String name);

}

package echo.service.impl;

import java.text.SimpleDateFormat;
import java.util.Calendar;

import echo.service.EchoService;

public class EchoServiceImpl implements EchoService {

	public String echo(String name) {
		if (name == null || name.trim().length() == 0) {
			return "echo back: -please provide a name-";
		}
		SimpleDateFormat dtfmt = new SimpleDateFormat("MM-dd-yyyy hh:mm:ss a");
		return "echo back: name " + name + " received on " + dtfmt.format(Calendar.getInstance().getTime());
	}
}

package echo.endpoint;

import echo.service.EchoService;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.springframework.ws.server.endpoint.AbstractDomPayloadEndpoint;

public class EchoEndpoint extends AbstractDomPayloadEndpoint {

private EchoService echoService;

public void setEchoService(EchoService echoService) {
	this.echoService = echoService;
}

@Override
protected Element invokeInternal(Element arg0, Document arg1) throws Exception {
	//Dummy code
	echoService.echo("abc");
	return null;
}

}

WEB-INF\echo.xsd

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="qualified"
        targetNamespace="http://localhost:9080/schema"
        xmlns:tns="http://localhost:9080/schema">

    <element name="echoRequest">
        <simpleType>
            <restriction base="string">
                <pattern value="([A-Z]|[a-z])+"/>
            </restriction>
        </simpleType>
    </element>

    <element name="echoResponse" type="string"/>
</schema>

My Questiions:
1. WSDL is not getting exposed under : http://localhost:9080/echoservice/echo.wsdl

Is my prop EchoRequest in spring-ws-servlet.xml incorrect? I get error as: Error 404: No target servlet configured for uri: /echoservice/echo.wsdl

2. Is my namespace in echo.xsd incorrect?

What do I need to do to expose the WSDL?

Hello,
i had the same problem. If you look at the applicationContext.xml in the client package you will see that the defaultURI is : http://localhost:8080/echo-server/services.
So you can try http://localhost:8080/echo-server/services/echo.wsdl or http://localhost:9080/echo-server/services/echo.wsdl
But i can't explain it.
