本文将介绍如何使用Tomcat5.0Apache Axis2开发、部署及测试一个简单的Web Service应用。

1工作环境
Eclipse 3.1.2+Lomboz+jdk1.5+ apache-tomcat-5.0.18+AXIS2:1.0(war版本和bin版本)
[url]http://ws.apache.org/axis2/download/1_0/download.cgi[/url]页面下载AXIS2Binary Distribution url: [url]http://apache.justdn.org/ws/axis2/1_0/axis2-std-1.0-bin.zip[/url]war Distribution url: [url]http://apache.justdn.org/ws/axis2/1_0/axis2-1.0-docs.zip[/url]。把这两个文件解压,比如解压缩的后得目录为C:\axis2-std-1.0-binC:\axis2.war
Eclipse下通过菜单window—preferences…--Java—Build Path—User Libraries 新建一个user library,比如名字就叫axis2C:\axis2-std-1.0-bin\lib下的所有jar文件包含进来。把axis2.war拷贝到%TOMCAT-HOME%/webapps下面。
 
2.检验安装
Eclipse下启动Tomcat,在地址栏内输入[url]http://localhost:8080/axis2/[/url]
点击Validate,将到达 Axis2 Happiness Page
3WebService中的HelloWorld
1)新建一个动态web工程,取名ZZaxis,右键点击项目名,选择Properties-Java Build Path-Add Library-User Library-axis2
 
2)新建package sample,建立HelloWorld.java,代码如下。
HelloWorld.java
import org.apache.axiom.om.OMAbstractFactory;
import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.OMFactory;
import org.apache.axiom.om.OMNamespace;
 
public class HelloWorld {
       public OMElement sayHello(OMElement in){
              String name=in.getText();
              String info=name+"HelloWorld!";
              OMFactory fac=OMAbstractFactory.getOMFactory();
              OMNamespace omNs=fac.createOMNamespace("http://helloworld.com/","hw");
              OMElement resp=fac.createOMElement("sayHelloResponse",omNs);
              resp.setText(info);
              return resp;
       }
}
 
3)在WebContent\META-INF\建立services.xml,代码如下。
services.xml
<?xml version="1.0" encoding="UTF-8"?>
<service name="HelloWorld">
<description>
  This is a sample Web Service.
</description>
<parameter name="ServiceClass" locked="false">sample.HelloWorld</parameter>
<operation name="sayHello">
  <messageReceiver class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver"/>
</operation>
</service>
 
4)将目录sample和目录META-INF组织如下(新建目录example)。
+-example
|-------- +-sample
    |------- HelloWorld.class
|---------+-META-INF
       |------- services.xml
 
5)打包生成aar文件。
在命令符环境下,将当前目录转到example
jar cvf HelloWorld.aar . //注意最后一个点,在当前目录下生成HelloWorld.aar
 
6)在Eclipse中启动Tomcat,在地址栏下键入[url]http://localhost:8080/axis2/[/url]。选择Administration,输入用户名admin,密码axis2。选择左侧工具栏Tools- Upload Service,上传之前打包的HelloWorld.aar。该文件将在<CATALINA_HOME>/webapps/axis2\WEB-INF\services目录下。
 
7)编写客户端检验代码。新建Java Project,取名为ZZaxisClient。右键点击项目名,选择Properties-Java Build Path-Add Library-User Library-axis2
 
8)新建package example.client。建立TestClient.java,代码如下。
TestClient.java
package example.client;
 
import org.apache.axiom.om.OMAbstractFactory;
import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.OMFactory;
import org.apache.axiom.om.OMNamespace;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.client.ServiceClient;
 
public class TestClient {
       private static EndpointReference targetEPR=new EndpointReference
         ("http://localhost:8080/axis2/services/HelloWorld");
       public static OMElement getSayHelloOMElement(){
              OMFactory fac=OMAbstractFactory.getOMFactory();
              OMNamespace omNs=fac.createOMNamespace("http://helloworld.com/","hw");
              OMElement method=fac.createOMElement("sayHello",omNs);
              method.setText("ZJ");
              return method;
       }
       public static void main(String[] args){
              try{
                     Options options=new Options();
                     options.setTo(targetEPR);
                     ServiceClient sender=new ServiceClient();
                     sender.setOptions(options);
                     OMElement sayHello=TestClient.getSayHelloOMElement();
                     OMElement result=sender.sendReceive(sayHello);
                     System.out.println(result);
              }
              catch(Exception axisFault){
                     axisFault.printStackTrace();
              }
       }
}
 
9)测试,run TestClient.java as Java Application。结果:
<hw:sayHelloResponse xmlns:hw="http://helloworld.com/"
xmlns:tns="http://ws.apache.org/axis2">
ZJHelloWorld!
</hw:sayHelloResponse>
