一、axis安装
1.环境
J2SE SDK 1.3 or 1.4: 我使用 1.4.2
Servlet Container: 我使用Tomcat 5.0
2.到 http://ws.apache.org/axis/网站下载axis安装包
3.解压缩安装包，将AXIS_UNZIP_PATH\axis-version\webapps下的axis包拷贝到TOMCAT_HOME\webapps\下，
以下约定AXIS_HOME为该TOMCAT_HOME\webapps\axis目录
4.启动tomcat,访问http://localhost:8080/axis 检查安装是否成功
5.以上步骤执行成功，可以开发webservice例子了
axis支持三种web service的部署和开发，分别为：
1。Dynamic Invocation Interface ( DII)
2。 Stubs方式
3。Dynamic Proxy方式
以下逐一讲述web service在axis上的部署和开发，设置classpath
set CLASSPATH=.;%AXIS_HOME%\lib\axis.jar;%AXIS_HOME%\lib\axis-ant.jar;%AXIS_HOME%\lib\commons-discovery-0.2.jar;%AXIS_HOME%\lib\commons-logging-1.0.4.jar;%AXIS_HOME%\lib\jaxrpc.jar;%AXIS_HOME%\lib\saaj.jar;%AXIS_HOME%\lib\wsdl4j-1.5.1.jar;%AXIS_HOME%\lib\log4j-1.2.8.jar;E:/thirdparty/activation/activation.jar;E:/thirdparty/activation/mail.jar
二、编写DII(Dynamic Invocation Interface )方式web服务
1.编写服务端程序HelloClient
public class HelloClient {
public String getName(String name)
{
return "hello "+name;
}
}
2.将源码拷贝到AXIS_HOME下，重命名为 HelloClient.jws
3.访问连接http://localhost:8080/axis/HelloClient.jws?wsdl，页面显示axis自动生成的wsdl
4.编写访问服务的客户端 TestHelloClient.java
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;
import javax.xml.rpc.ServiceException;
import java.net.MalformedURLException;
import java.rmi.RemoteException;
public class SayHelloClient2 {
public static void main(String[] args) {
try {
String endpoint = "http://localhost:8080/axis/HelloClient.jws";
Service service = new Service();
Call call = null;
call = (Call) service.createCall();
call.setOperationName(new QName(
"http://localhost:8080/axis/HelloClient.jws", "getName"));
call.setTargetEndpointAddress(new java.net.URL(endpoint));
String ret = (String) call.invoke(new Object[] {"zhangsan"});
System.out.println("return value is " + ret);
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
三、编写Dynamic Proxy方式访问服务
1.编写部署服务端程序，同上边DII方式，本次仍使用上边部署的HelloClient
2.编写代理接口
public interface HelloClientInterface extends java.rmi.Remote {
public String getName(String name) throws java.rmi.RemoteException;
}
3.编写并执行客户端程序TestHelloClient.java
import javax.xml.rpc.Service;
import javax.xml.rpc.ServiceFactory;
import java.net.URL;
import javax.xml.namespace.QName;
public class TestHelloClient {
public static void main(String[] args) {
try
{
String wsdlUrl = "http://localhost:8080/axis/HelloClient.jws?wsdl";
String nameSpaceUri = "http://localhost:8080/axis/HelloClient.jws";
String serviceName = "HelloClientService";
String portName = "HelloClient";
ServiceFactory serviceFactory = ServiceFactory.newInstance();
Service afService = serviceFactory.createService(new URL(wsdlUrl),
new QName(nameSpaceUri, serviceName));
HelloClientInterface proxy = (HelloClientInterface)
afService.getPort(new QName(
nameSpaceUri, portName), HelloClientInterface.class);
System.out.println("return value is "+proxy.getName("john") ) ;
}catch(Exception ex)
{
ex.printStackTrace() ;
}
}
}
四、编写wsdd发布web服务，编写stub client访问web服务
1.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;
}
}
2.编写LogHandler.java
import org.apache.axis.AxisFault;
import org.apache.axis.Handler;
import org.apache.axis.MessageContext;
import org.apache.axis.handlers.BasicHandler;
import java.util.Date;
public class LogHandler extends BasicHandler {
public void invoke(MessageContext msgContext) throws AxisFault
{
/** Log an access each time we get invoked.
*/
try {
Handler serviceHandler = msgContext.getService();
Integer numAccesses =
(Integer)serviceHandler.getOption("accesses");
if (numAccesses == null)
numAccesses = new Integer(0);
numAccesses = new Integer(numAccesses.intValue() + 1);
Date date = new Date();
String result = date + ": service " +
msgContext.getTargetService() +
" accessed " + numAccesses + " time(s).";
serviceHandler.setOption("accesses", numAccesses);
System.out.println(result);
} catch (Exception e) {
throw AxisFault.makeFault(e);
}
}
}
3..编写wsdd文件
deploy.wsdd
<deployment xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<handler name="print" type="java:LogHandler"/>
<service name="sayhello" provider="java:RPC">
<requestFlow>
<handler type="print"/>
</requestFlow>
<parameter name="className" value="server.SayHello"/>
<parameter name="allowedMethods" value="*"/>
</service>
</deployment>
3.将编译后的文件拷贝到AXIS_HOME/WEB-INF/classes下，如：D:\tomcat\webapps\axis\WEB-INF\classes
4.发布服务：
java org.apache.axis.client.AdminClient deploy.wsdd
5.生成client stub文件
a:方式1
将SayHello.java拷贝到AXIS_HOME/下，重命名为SayHello.jws，执行下面的命令生存client stub
java org.apache.axis.wsdl.WSDL2Java -p client http://localhost:8080/axis/services/SayHello.jws?wsdl
b:方式2
执行如下命令生成SayHello.wsdl
java org.apache.axis.wsdl.Java2WSDL -oSayHello.wsdl -lhttp://localhost:8080/axis/services/SayHello -nsayhello server.SayHello
执行如下命令生成client stub
java org.apache.axis.wsdl.WSDL2Java SayHello.wsdl -p client
生成的stub client文件列表为：
1。SayHello.java
2。SayHelloService.java。
3。SayHelloServiceLocator.java
4。SayHelloSoapBindingStub.java
6.编写客户端程序，编译并执行
public class SayHelloClient {
public static void main(String[] args) {
try {
SayHelloService service = new client.
SayHelloServiceLocator();
client.SayHello_PortType client = service.getSayHello();
String retValue=client.getName("zhangsan");
System.out.println(retValue);
} catch (Exception e) {
System.err.println("Execution failed. Exception: " + e);
}
}
}
