SPRING AND CXF

CXF by example by Martin Nad [email protected]

Spring and CXF

OVERVIEW

This paper is focused to the CXF and using whitin Spring.

The first example is a simple classic hello application, to show what is the minimal requirement to use CXF with the Spring.

The second example is showing how you can send the parameters to the web service

The third one is just another example in different aspect.

Spring and CXF

Spring and CXFHere, I will show very shortly and easily how to use CXF in Spring, step by step.

As you know there are several ways to implement webservice with CXF in java

For example Pojo and with help of annotation

First I will show to how make webservice in java annotation and the exactly same application with POJO method later.

Hello world with java annotation

The pom-file should looks like this:

helloWorld service

Spring and CXF

You need an interface for you servie and it can look like this one:

package org.martin;

import javax.jws.WebService;

@WebService

public interface HelloWorld {

String sayHello(String text);

}

Hello world implementation

And the implementation of helloword-interface can look like this one

package org.martin;

import javax.jws.WebService;

@WebService(endpointInterface = "org.martin.HelloWorld")

public class HelloWorldImpl implements HelloWorld {

public String sayHello(String text) {

System.out.println("server called, and argument name is: "+text);

return "Hello " + text;

}

}

Application-context

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:jaxws="http://cxf.apache.org/jaxws"

xsi:schemaLocation="

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

Page 6

Spring and CXF

Application-context

<jaxws:endpoint

id="helloWorld"

implementor="org.martin.HelloWorldImpl"

address="/HelloWorld" />

</beans>

Web.xml

And the web.xml can look like:

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app

PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

"http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>WEB-INF/applicationContex.xml</param-value>

</context-param>

<listener>

<listener-class>

org.springframework.web.context.ContextLoaderListener

</listener-class>

</listener>

Web.xml

<servlet>

<servlet-name>CXFServlet</servlet-name>

Page 7

Spring and CXF

<display-name>CXF Servlet</display-name>

<servlet-class>

org.apache.cxf.transport.servlet.CXFServlet

</servlet-class>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>CXFServlet</servlet-name>

<url-pattern>/*</url-pattern>

</servlet-mapping>

</web-app>

Build package

Now you should build package and make sure the .war file is on the deploy folder at jboss server

Check this url and see if you see any wsdl

http://localhost:8080/cfx-spring-1.0/HelloWorld?wsdl

And now you need a client to call the service..

Client-pom

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

I’m sure you don’t need all element in this pom. But for simplifying I put all information in this pom to know how you can work with client-side-pom.

When you are finish with your pom. Just run the empty application.

It will automatically call your service and convert your wsdl to java and make for you a folder hirarchey

Client-java

And now just write client with help of the java-files as follows...

package dk.martin.project.cfxspringClient;

/**

* Hello world!

*

*/

public class App

{

public static void main( String[] args ) throws Exception

{

App app = new App();

app.test1HelloWorldImplPortSayHi("martin");

}

public void test1HelloWorldImplPortSayHi(String name) throws Exception {

dk.martin.helloWord.HelloWorldImplServiceSoapBindingStub binding;

try {

binding = (dk.martin.helloWord.HelloWorldImplServiceSoapBindingStub)

new dk.martin.helloWord.HelloWorldImplServiceLocator().getHelloWorldImplPort();

Page 14

Spring and CXF

}

catch (javax.xml.rpc.ServiceException jre) {

if(jre.getLinkedCause()!=null)

jre.getLinkedCause().printStackTrace();

throw new junit.framework.AssertionFailedError("JAX-RPC ServiceException caught: " + jre);

}

binding.setTimeout(60000);

java.lang.String value = null;

value = binding.sayHi(name);

System.out.println("value is: "+value);

}

}

information

And last if you run your client it should work....

If you want the both client and server example just sends a email to me [email protected] and I will send you the both example
