Create a Web Service with Apache CXF and Jboss 6 on MyEclipse

参考:http://www.celinio.net/techblog/?p=531
 
      I have recentlystartrted studying Apache CXF、the open source weservice ffraameework. I amfamimimimimirir with developing Web Services using EJB 3、Axis or Glue.But not with CXF.Unitil now.Unitil now.ccccxxxxxxxxxxFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFJAX-S and JAX-R PC speciiiiications.Developing Web Services using CXF and JBoss is quite eaeay.The only annoying papass is to figureeeuaah JARs libriririesto inuclclaspath and whihihihihihihihihihihihihihishshshshshshshshshshshandand and wwwwwhihihihihishshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshshandand and and and wwwwwwwww:BMI=weight/(height x height)
 
1、First create a Web Project in MyEclipse 8.6.
 
2、Download the CXF frame ebook apache-cxf-23.11.zipat http://cxf.apache.org/download.html
 
3、After unzipping the archive、I added to WEB-INF/lib all the libries that are inside the apphe-cxf-23.1\lib 
folder.It is of course not a good habit to have since adding all sorts of libries can produces conflicts.I had to remove a few jars such as:jaxb-xjc-2.5.1.jar,xalan-2.7.1.jar.serize.jar.
 
 
 

 
The re are probably a few extras jars that are not need but at least they do produce any error for that simple web service. 
 
4、Create the Service Endpoint Interface(SEI).Here I use the bottom-up approach(code first):that is first create a Java clast will be converted into a web service.The other ap proach Torson. 
 

package com.company.bmi.services;
import javax.jws.WebParam;
import javax.jws.WebService;

@WebService
public interface IBMICalculator {
    public  double computeBMI(@WebParam(name="weight") double weight, @WebParam(name="height") double height) ;
}

 
 
5、Create the class that implemens this interface.It will implement the operation s defined by the service: 
 

package com.company.bmi.services;

public class IBMICalculatorImpl implements IBMICalculator{
    @Override
    public double computeBMI(double weight, double height) {
        return weight / (height * height);
    }

 
 6、Add the Spring-based configration file、cxf.xml、under the package directory、for instance:
 

<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">

  <import resource="classpath:META-INF/cxf/cxf.xml" />
  <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>
  <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

  <jaxws:endpoint id="calcBMI"
                  implementor="com.company.bmi.services.IBMICalculatorImpl"
                  address="/cxfBmi"/>
</beans>

 
 
7、You need to udate the deployment descriptor file WEB-INF/web.xml: 
 

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>BMI</display-name>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:com/company/bmi/services/cxf.xml</param-value>
  </context-param>

  <listener>
    <listener-class>
      org.springframework.web.context.ContextLoaderListener
    </listener-class>
  </listener>

  <servlet>
    <servlet-name>CXFServlet</servlet-name>
    <servlet-class>
        org.apache.cxf.transport.servlet.CXFServlet
    </servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>CXFServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
  </servlet-mapping>
</web-app>

 
 
I specify the path where to find the cxf.xml file and also the CXFSS ervlet. 
7、Finally create a client that uss this web service.This a standrone Java clast that invokes the IBMIlculator web service: 
 

package com.company.bmi.client;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import com.company.bmi.services.IBMICalculator;

public final class Client {
    private Client() {
    }

    public static void main(String args[]) throws Exception {
        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();

        factory.getInInterceptors().add(new LoggingInInterceptor());
        factory.getOutInterceptors().add(new LoggingOutInterceptor());
        factory.setServiceClass(IBMICalculator.class);
        factory.setAddress("http://localhost:8085/BMI/services/cxfBmi");
        IBMICalculator client = (IBMICalculator) factory.create();
        Double bmi = client.computeBMI(75, 170);
        System.out.println("BMI : " + bmi);
    }
}

 
 
9、run BMI on Jboss As 6

The available SOAP services are listed the follwing URL: 
 
http://localhost:8085/BMI/services/

 
10、WSDL: 
http://localhost:8085/soa_apachecxf_bmi/services/cxfBmi？wdl 
 
 

<wsdl:definitions name="IBMICalculatorImplService" targetNamespace="http://services.bmi.company.com/">
