Eclipse&Tomcat下的SOAP实现

紫冰

1.需要的jar包:activation.jar mail.jar soap.jar xercesImpl.jar xercesSamples.jar xml-apis.jar xmlParserAPIs.jar

2.新建web service工程,取名soap,目录树如下,其中我们将\soap-2_3_1\webapps\soap\下的几个文件copy到了工程的webroot下.
   


3.用到的源文件:

//HelloService.java
package org.eleaf.soap;
import java.util.Date;
public class HelloService {
public String sayHello(String username)
{
  return "Hello this is binger:" + username;
}
public Date getDate()
{
  return new Date();
}
public int sum(int i, int j)
{
  return i+j;
}
}



//HelloClient.java
package org.eleaf.soap;
import java.net.URL;
import java.util.Vector;
import org.apache.soap.Constants;
import org.apache.soap.Fault;
import org.apache.soap.rpc.Call;
import org.apache.soap.rpc.Parameter;
import org.apache.soap.rpc.Response;
public class HelloClient {
/**
  * @param args
  */
public static void main(String[] args) throws Exception{
  URL url = new URL("
http://localhost:8080/soap/servlet/rpcrouter
");
  //localhost可以改为服务所在的ip地址
  
  Call call = new Call();
  call.setTargetObjectURI("urn:helloservice");
  call.setMethodName("sayHello");
  call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
  Vector params = new Vector();
  params.addElement(new Parameter("username", String.class, "bitan", null));
  call.setParams(params);
  Response resp = call.invoke(url, "");
  if (resp.generatedFault())
  {
   Fault fault = resp.getFault();
   System.out.println("[code:" + fault.getFaultCode() +
     "];[description:" + fault.getFaultString() + "]");
  }
  else
  {
   Parameter result = resp.getReturnValue();
   System.out.println("[value:" + result.getValue() + "];[name:" +
     result.getName() + "];[class:" + result.getClass() +
     "];[type:" + result.getType() + "];[encoding:" +
     result.getEncodingStyleURI() + "]");
  }
  call.setMethodName("getDate");
  call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
  call.setParams(null);
  resp = call.invoke(url, "");
  if (resp.generatedFault())
  {
   Fault fault = resp.getFault();
   System.out.println("[code:" + fault.getFaultCode() +
     "];[description:" + fault.getFaultString() + "]");
  }
  else
  {
   Parameter result = resp.getReturnValue();
   System.out.println("[value:" + result.getValue() + "];[name:" +
     result.getName() + "];[class:" + result.getClass() +
     "];[type:" + result.getType() + "];[encoding:" +
     result.getEncodingStyleURI() + "]");
  }
   
  call.setMethodName("sum");
  call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
  params = new Vector();
  params.addElement(new Parameter("i", int.class, new Integer(24), null));
  params.addElement(new Parameter("j", int.class, new Integer(37), null));
  call.setParams(params);
  resp = call.invoke(url, "");
  if (resp.generatedFault())
  {
   Fault fault = resp.getFault();
   System.out.println("[code:" + fault.getFaultCode() +
     "];[description:" + fault.getFaultString() + "]");
  }
  else
  {
   Parameter result = resp.getReturnValue();
   System.out.println("[value:" + result.getValue() + "];[name:" +
     result.getName() + "];[class:" + result.getClass() +
     "];[type:" + result.getType() + "];[encoding:" +
     result.getEncodingStyleURI() + "]");
  }
}
}



//DeploymentDescriptor.xml
   
        
   

PS:这个文件手工编译的时候用,用soap自带的发布工具就不用了.


4.在tomcat上发布,然后在浏览器上输入:http://localhost:8080/soap/admin/  进入deploy页面,填入下面的信息:

ID
Scope
Request Session Application
Methods
(Whitespace separated list of method names)
Provider Type
Java Script User-Defined
For User-Defined Provider Type, Enter FULL Class Name:

发布后,进入到list页面可以看到一个名为:
urn:helloservice
  的服务,说明已经发布成功;

5.运行一下HelloClient,注意将里面的url改成服务所在的地址.会看到这样的response:

  [value:Hello this is binger:bitan];[name:return];[class:class org.apache.soap.rpc.Parameter];[type:class java.lang.String];[encoding:null]
[value:Tue Jul 22 21:15:19 CST 2008];[name:return];[class:class org.apache.soap.rpc.Parameter];[type:class java.util.Date];[encoding:null]
[value:61];[name:return];[class:class org.apache.soap.rpc.Parameter];[type:int];[encoding:null]

6.用WireShark抓包:XML格式的只能截图了,可我在这里没有传图片的空间了.将就着看吧

7.出现的问题:

在linux下可以抓到本地请求和回应的http包,但是在windows下不行,所以,我让一哥们在另一台机子上布置了工程,向我的机子发送请求,这个问题还没搞懂为什么?有高手可以指点一下.

tomcat安装目录/conf/server.xml中网上有资料要加一句:
