Axis_1.4中Chain特性异常
大体介绍一下环境：
写了一个简单的利用Axis_1.4的chain定制发布的小WS.
1.两个Handler，实现其invoke，并在该方法中记录访问该service的次数信息;
代码如下：
package com.test.wsddhandler;
import org.apache.axis.AxisFault;
import org.apache.axis.MessageContext;
import org.apache.axis.handlers.BasicHandler;
public class HelloWorldHandler extends BasicHandler {
?/**
? *
? */
?private static final long serialVersionUID = -3658682483583772974L;
?private static long count = 0l;
?
?private int reqCount = 0;
?
?public void invoke(MessageContext arg0) throws AxisFault {
??// TODO Auto-generated method stub
??count ++ ;
??reqCount ++ ;
??String status = (String) this.getOptions().get("status");
??System.out.println("HelloWorldHandler's status is : " + status + ",COUNT = " + count
????+" Handler Request Count = " + reqCount );
?}
}
package com.test.wsddchain;
import org.apache.axis.AxisFault;
import org.apache.axis.MessageContext;
import org.apache.axis.handlers.BasicHandler;
public class HelloWorldHandler2 extends BasicHandler{
?
?/**
? *
? */
?private static final long serialVersionUID = -2144111744853166634L;
?private static long count = 0l;
?
?private int reqCount = 0;
?
?public void invoke(MessageContext arg0) throws AxisFault {
??// TODO Auto-generated method stub
??count ++ ;
??reqCount ++ ;
??String status = (String) this.getOptions().get("status");
??System.out.println("HelloWorldHandler2's status is : " + status + ",COUNT = " + count
????+" Handler Request Count = " + reqCount );
?}
}
2.一个Chain，分别将两个Handler添加进来；
代码如下：
? package com.test.wsddchain;
import org.apache.axis.SimpleChain;
import com.test.wsddhandler.HelloWorldHandler;
public class HelloWorldChain extends SimpleChain {
?/**
? *
? */
?private static final long serialVersionUID = -2925126901439174032L;
?public HelloWorldChain() {
??// TODO Auto-generated constructor stub
?
??HelloWorldHandler handler = new HelloWorldHandler();
??HelloWorldHandler2 handler2 = new HelloWorldHandler2();
??
??this.addHandler(handler);
??this.addHandler(handler2);
?}
}
?
3.发布描述文件如下：
<deployment xmlns="http://xml.apache.org/axis/wsdd/"
?xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">??
?
?<chain name="HelloWorldChain">
??<handler type="java:com.sinosoft.wsddchain.HelloWorldChain"/>
?</chain>
?<service name="HelloWorldWSDDChain" provider="java:RPC">
??<requestFlow>
???<chain type="HelloWorldChain"/>
??</requestFlow>??
??<parameter name="className" value="com.sinosoft.wsdd.HelloWorldWSDD"/>??
??<parameter name="allowedMethods" value="*"/>
??<parameter name="scope" value="request"/>?
?</service>
???
</deployment>?
?
发布是没有问题的，
And now... Some ServicesHelloWorldWSDD (wsdl) hello add AdminService (wsdl) AdminService HelloWorldWSDDChain (wsdl) hello add HelloWorldWSDDHandler (wsdl) hello add Version (wsdl) getVersion4.测试客户程序如下：
package com.test.wsddchain;
import java.rmi.RemoteException;
import javax.xml.namespace.QName;
import javax.xml.rpc.ServiceException;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
public class ClientWSDDChain {
?/**
? * @param args
? */
?public static void main(String[] args) {
??// TODO Auto-generated method stub
??
??try {
???String url = "http://localhost:8080/axis/services/HelloWorldWSDDChain";
???Service serv = new Service();
???
???Call call = (Call) serv.createCall();
???call.setTargetEndpointAddress(url);
???
???call.setOperationName(new QName(url,"hello"));
???String result = (String) call.invoke(new Object[]{"wsdd chain"});
???System.out.println("result : " + result);
???
???call.setOperationName(new QName(url,"add"));
???Float resultVal = (Float) call.invoke(new Object[]{new Float(3.5),new Float(4.7)});
???System.out.println("add result : " + resultVal);
???
??} catch (ServiceException e) {
???// TODO Auto-generated catch block
???e.printStackTrace();
??} catch (RemoteException e) {
???// TODO Auto-generated catch block
???e.printStackTrace();
??}
?}
}
直接运行4，报以下的错误：
