什么是AXIS2就不介绍了，主要介绍的是如何利用AXIS2快速的实现一个Web Service。本文以实例说明了一个Web Service的创建、部署褐调用的过程。
本文使用的AXIS2的版本是1.1.1，Tomcat版本是6.0.10，JDK版本是1.5，操作系统WinXP SP2，IE浏览器IE6 SP2。
一、服务Java Bean的编写，以下是java代码
1 package cn.net.ynst;

3 import cn.net.ynst.nativecode.JavaDLL;
4 import cn.net.ynst.nativecode.Service;
5 import cn.net.ynst.nativecode.Services;

10 import org.apache.axiom.om.OMFactory;

15 System.loadLibrary("JavaDLL");
16 }
17
18 public String getWindowsDirectory() {
19 return JavaDLL.getWindowsDirectory();
20 }

22 public String getSystemDirectory() {
23 return JavaDLL.getSystemDirectory();
24 }
25
26 public String getMoudlePath() {
27 return JavaDLL.getMoudlePath();
28 }
29
30 public String getCurrentDirectory() {

36 }
37
38 public int getWindowsMinorVersion() {
39 return JavaDLL.getWindowsMinorVersion();
40 }
41
42 public int getWindowsBuilderNo() {
43 return JavaDLL.getWindowsBuilderNo();
44 }
45
46 public int getWindowsPlatformId() {

48 }
49
50 public String getWindowsVersion() {
51 StringBuffer sb = new StringBuffer();
52 JavaDLL.getWindowsVersion(sb);
53
54 return sb.toString();
55 }
56
57 public String getWindowsVersionA() {
58 return JavaDLL.getWindowsVersionA();
59 }
60

63 }
64

67 }
68
69 public String getWindowsSystemInfo() {
70 StringBuffer sb = new StringBuffer();
71 JavaDLL.getWindowsSystemInfo(sb);
72
73 return sb.toString();
74 }
75
76 public String getEnvironmentStrings() {
77 StringBuffer sb = new StringBuffer();
78 JavaDLL.getEnvironmentStrings(sb);
79
80 return sb.toString();
81 }
82
83 public String getVersion() {
84 return JavaDLL.getVersion();
85 }
86
87 public String getComputerName() {
88 return JavaDLL.getComputerName();
89 }
90
91 public String getUserName() {
92 return JavaDLL.getUserName();
93 }
94
95 public String getProcessList() {
96 StringBuffer sb = new StringBuffer();
97 JavaDLL.getProcessList(sb);
98
99 return sb.toString();
100 }
101
102 public String getServiceList() {
103 Services services = new Services();
104 JavaDLL.getServiceList(services);
105
106 Service[] array = services.getServices();
107 StringBuffer sb = new StringBuffer();
108 for(int i=0; i<array.length; i++) {
109 Service service = array[i];
110 sb.append(service);
111 sb.append("<BR>");
112 }
113
114 return sb.toString();
115 }
116
117 public OMElement getUser(OMElement in_name, OMElement in_pass) {
118 OMFactory fac = OMAbstractFactory.getOMFactory();
119 OMNamespace omNs = fac.createOMNamespace("http://ynst.net.cn/xsd", "ns1");
120
121 OMElement user = fac.createOMElement("user", omNs);
122 OMElement name = fac.createOMElement("name", omNs);
123 name.setText("jacky_zz");
124 if(in_name != null) name.setText(in_name.getText());
125
126 OMElement pass = fac.createOMElement("pass", omNs);
127 pass.setText("123456");
128 if(in_pass != null) pass.setText(in_pass.getText());
129
130 user.addChild(name);
131 user.addChild(pass);
132
133 return user;
134 }
135 }二、Web服务描述文件

66 </service>三、文件打包
将类文件和Web服务描述文件打包为aar文件
四、部署
将aar文件复制到<TOMCAT>/webapps/axis2/WEB-INF/services目录下，并修改文件services.list，将aar文件名复制到该文件并保存。
五、浏览器调用

5 body {font-size:12px; font-family:Tahoma}

本文实现的Web服务使用了JNI来实现了部分的代码，JNI通过VC++开发实现。
