Java Lovers blog: Simple Web service client

Devloping A CXF web service client

A web service client can be devloped using the WSDL file of the web service application.

Procedure to create a webservice client.

Step-1

Create a maven project with directory like...

src/main/java

src/main/resources

src/main/webapp

create a pom.xml file under the project folder.

Step-2

Get WSDL file and paste it under src/main/resources and get the java classes from from that WSDL file by adding the following in you pom file..like..

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Build that and copy the java classes from generated/cxf directory to your src/main/java packge directory by under one java package like me..

Step-2.

Create a simple servlet class that extends from HttpServlet class and will have service or doXXX method and write the code under that method like..
We can prepare the web service client in two ways.

with spring
without spring

without spring

package com.cxf.service;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServlet;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.cxftest.FormatRequest;
import com.cxftest.NameFormatterService;

public class CxfClient extends HttpServlet{
 public void service(HttpServletRequest request, HttpServletResponse response) {

 JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();

 factory.setServiceClass(NameFormatterService.class);
 factory.setAddress("http://localhost:8082/CXFTest-1.0-SNAPSHOT/format?wsdl");
 factory.getInInterceptors().add(new LoggingInInterceptor());
 factory.getOutInterceptors().add(new LoggingOutInterceptor());

 NameFormatterService client = (NameFormatterService) factory.create();
 FormatRequest student = new FormatRequest();
 student.setFirstName("Syntel Ltd");
 student.setLastName("It is a good company");
 /* Student changeName = client.changeName(student); */
 out.println("Server said: " + student.getFirstName()+" ");
 out.println("Server said: " + student.getLastName()+" ");
 out.println("Welcome to india");
 }
}

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_2_5.xsd"
id="WebApp_ID" version="2.5">

<servlet>
 <servlet-name>helloWs</servlet-name>
 <servlet-class>com.cxf.service.CxfClient</servlet-class>
 <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
 <servlet-name>helloWs</servlet-name>
 <url-pattern>/HelloWs</url-pattern>
</servlet-mapping>

</web-app>

and the output is

With spring cxf.

FormatRequest student = new FormatRequest();
 student.setFirstName("Syntel Ltd");
 student.setLastName("It is a good company");
 /* Student changeName = client.changeName(student); */
 out.println("Server said: " + student.getFirstName()+" ");
 out.println("Server said: " + student.getLastName()+" ");
 out.println("Welcome to india");
}
}

and the spring configuration file is..

applicationContext.xml

and same web.xml file.

Step-4

Run the pom file with "mvn -e clean install" and deploy the war file in server and launch the url so that the request will directly go the servlet class..
