使用Axis开发Web Service程序
1、新建一个Web工程，工程名为“AxisTest”：
2、新建“lib”文件夹，然后把主要JAR包：axis.jar，commons-discovery-0.2.jar，commons-logging-1.0.4.jar，jaxrpc.jar，wsdl4j-1.5.1.jar，saaj.jar；可选包（发布服务及生成客户端程序是要用到的）：activation.jar；mail.jar都拷贝到此“lib”文件夹下，并把主要的JAR包添加到工程的classpath中；
3、配置“web.xml”：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>Apache-Axis</display-name>
<listener>
<listener-class>org.apache.axis.transport.http.AxisHTTPSessionListener</listener-class>
</listener>
<servlet>
<servlet-name>AxisServlet</servlet-name>
<servlet-class>
org.apache.axis.transport.http.AxisServlet
</servlet-class>
</servlet>
<servlet>
<servlet-name>AdminServlet</servlet-name>
<servlet-class>
org.apache.axis.transport.http.AdminServlet
</servlet-class>
<load-on-startup>100</load-on-startup>
</servlet>
<servlet>
<servlet-name>SOAPMonitorService</servlet-name>
<servlet-class>
org.apache.axis.monitor.SOAPMonitorService
</servlet-class>
<init-param>
<param-name>SOAPMonitorPort</param-name>
<param-value>5001</param-value>
</init-param>
<load-on-startup>100</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>AxisServlet</servlet-name>
<url-pattern>/servlet/AxisServlet</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>AxisServlet</servlet-name>
<url-pattern>*.jws</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>AxisServlet</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>SOAPMonitorService</servlet-name>
<url-pattern>/SOAPMonitor</url-pattern>
</servlet-mapping>
<!-- uncomment this if you want the admin servlet -->
<!--
<servlet-mapping>
<servlet-name>AdminServlet</servlet-name>
<url-pattern>/servlet/AdminServlet</url-pattern>
</servlet-mapping>
-->
<session-config>
<session-timeout>20</session-timeout>
</session-config>
<!-- currently the W3C havent settled on a media type for WSDL;
http://www.w3.org/TR/2003/WD-wsdl12-20030303/#ietf-draft
for now we go with the basic 'it's XML' response -->
<mime-mapping>
<extension>wsdl</extension>
<mime-type>text/xml</mime-type>
</mime-mapping>
<mime-mapping>
<extension>xsd</extension>
<mime-type>text/xml</mime-type>
</mime-mapping>
<welcome-file-list id="WelcomeFileList">
<welcome-file>index.jsp</welcome-file>
<welcome-file>index.html</welcome-file>
<welcome-file>index.jws</welcome-file>
</welcome-file-list>
</web-app>
可参照“axis-1_4\webapps\axis\WEB-INF\web.xml”进行配置；
4、编写服务端程序server，SayHello.java，编译server.SayHello.java
package server;
public class SayHello
{
public String getName(String name)
{
return "hello "+name;
}
}
5、编写wsdd文件
deploy.wsdd文件内容如下：
<deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java=
"http://xml.apache.org/axis/wsdd/providers/java">
<service name="SayHello" provider="java:RPC">
<parameter name="className" value="server.SayHello.getName"/>
<parameter name="allowedMethods" value="*"/>
<parameter name="scope" value="session"/><!-- request, session, or application -->
</service>
</deployment>
6、把工程发布到Tomcat并启动Tomcat；
7、发布服务
编辑一个deploy.bat，Axis_Lib为axis.jar路径。内容如下：
set Axis_Lib=.\lib
set Java_Cmd=java -Djava.ext.dirs=%Axis_Lib%
set Axis_Servlet=http://localhost:8080/AxisTest/servlet/AxisServlet
%Java_Cmd% org.apache.axis.client.AdminClient -l%Axis_Servlet% deploy.wsdd
执行这个批处理文件，这时候，如果提示成功的话，访问http://localhost:8080/AxisTest/servlet/AxisServlet或http://localhost:8080/AxisTest/services就会显示服务列表。
8、生成客户端client stub文件
在浏览器上访问服务器端的服务，可以下载到WSDL文件，通过Axis的相关工具，可以自动从WSDL文件中生成Web Service的客户端代码。
编写一个WSDL2Java.bat文件，其内容如下：
set Axis_Lib=.\lib
set Java_Cmd=java -Djava.ext.dirs=%Axis_Lib%
set Output_Path=.\src
set Package=server.com
set wsdl_path=http://localhost:8080/AxisTest/services/ SayHello?wsdl
%Java_Cmd% org.apache.axis.wsdl.WSDL2Java -o%Output_Path% -p%Package% %wsdl_path%
执行这个批处理文件就可以生成client stub.
生成的stub client文件列表为：SayHello.java，SayHelloService.java，SayHelloServiceLocator.java，SayHelloSoapBindingStub.java .
9、编写客户端程序，编译并执行
1）、Stubs方式
下面是一段junit测试客户端代码。
import java.net.URL;
import junit.framework.Test;
import junit.framework.TestCase;
import junit.framework.TestSuite;
public class TestWSClient extends TestCase {
public TestWSClient(String string) {
super(string);
}
public void SayHelloClient() throws Exception {
SayHelloService service = new SayHelloServiceLocator();
SayHello_PortType client = service.getSayHello() ;
String retValue = client.getName("clientname");
System.out.println(retValue);
}
public static Test suite() {
TestSuite suite = new TestSuite();
suite.addTest(new TestWSClient("SayHelloClient"));
return suite;
}
}
2）、动态调用方式：
try {
// Options options = new Options(args);
String endpointURL = "http://localhost:8080/AxisTest/services/SayHello";
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress( new java.net.URL(endpointURL) );
call.setOperationName( new QName("SayHello", "getName") );
String res = (String) call.invoke( new Object[] {"Jack"} );
System.out.println( res );
} catch (Exception e) {
System.err.println(e.toString());
}
