天天看点

基于Tomcat5.0和Axis2开发Web Service应用实例

<b>1</b><b>.</b><b>工作环境</b>

Eclipse 3.1.2+Lomboz+jdk1.5+ apache-tomcat-5.0.18+AXIS2:1.0(war版本和bin版本)

在[url]http://ws.apache.org/axis2/download/1_0/download.cgi[/url]页面下,下载AXIS2的Binary Distribution url: [url]http://apache.justdn.org/ws/axis2/1_0/axis2-std-1.0-bin.zip[/url]和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-bin和C:\axis2.war。

在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axis2把C:\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。

<b>2</b><b>.检验安装</b>

点击Validate,将到达 Axis2 Happiness Page。

<b>3</b><b>.WebService</b><b>中的HelloWorld</b>

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

&lt;?xml version="1.0" encoding="UTF-8"?&gt;

&lt;service name="HelloWorld"&gt;

&lt;description&gt;

  This is a sample Web Service.

&lt;/description&gt;

&lt;parameter name="ServiceClass" locked="false"&gt;sample.HelloWorld&lt;/parameter&gt;

&lt;operation name="sayHello"&gt;

  &lt;messageReceiver class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver"/&gt;

&lt;/operation&gt;

&lt;/service&gt;

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&lt;CATALINA_HOME&gt;/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.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(){

              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:

&lt;hw:sayHelloResponse xmlns:hw="http://helloworld.com/"

xmlns:tns="http://ws.apache.org/axis2"&gt;

ZJHelloWorld!

&lt;/hw:sayHelloResponse&gt;
