    Apache SOAP  http://xml.apache.org/soap/index.html

    Tomcat4.0.4 http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.0.4/

    1.安装Apache SOAP到C盘根目录,即C:/soap-2_3_1

    2.安装Tomcat4.0.4到C:/Program Files/Apache Tomcat 4.0

    3.复制C:/soap-2_3_1/webapps/soap.war文件到C:/Program Files/Apache Tomcat 4.0/webapps目录下

    4.建立测试目录C:/soaptest和C:/soaptest/classes

    5.修改系统环境变量CLASSPATH,加入C:/soaptest/classes/test.jar

    6.启动Tomca4.0.4,方法有两个:A.执行C:/Program Files/Apache Tomcat 4.0/bin/startup.ba;B.通过系统管理的服务管理开启Apache Tomcat4.0.4

    7.建立测试java源文件,源文件应放置在目录C:/soaptest下

    //SimpleMath.javapackage test;public class SimpleMath{ public double getSinValue(double input) {  double ret = Math.sin(input);  return ret; }}---第二个JAVA源文件----------------

    //SimpleMathClient.javapackage test;import java.io.*;import java.net.*;import java.util.*;import org.apache.soap.util.xml.*;import org.apache.soap.*;import org.apache.soap.rpc.*;public class SimpleMathClient{        public static void main(String[] args) throws Exception {  System.err.println("SOAP call testing");  double value = Math.random();  SimpleMathClient smc = new SimpleMathClient();  //调用远程的SOAP服务  double returnValue = smc.doRequest(value);  System.err.println("the sin value of "+value +"is: "+returnValue); } public double doRequest(double value) throws Exception {  // Build the call.  Call call = new Call ();  //设置远程对象的URI  call.setTargetObjectURI ("urn:test.math.sin");  //设置调用的方法名  call.setMethodName ("getSinValue");  //设置编码风格  call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);  //设置方法调用的参数  Vector params = new Vector ();  params.addElement (new Parameter("input", double.class, new Double (value), null));  call.setParams (params);  //发送RPC请求  Response resp = call.invoke (new URL("http://127.0.0.1:8080/soap/servlet/rpcrouter"),"");  if (resp.generatedFault ()) {  //远程调用出错处理   Fault fault = resp.getFault ();   System.out.println ("the call failed: ");   System.out.println ("  Fault Code   = " + fault.getFaultCode ());   System.out.println ("  Fault String = " + fault.getFaultString ());   return 0.0d;  }   else { //调用成功,获取返回值   Parameter result = resp.getReturnValue ();   return ((Double)result.getValue()).doubleValue();  } }}

    8.编译java源文件,并打包   a. cd c:/soaptest   b. javac -d classes *.java   c. cd classes   d. jar -cvf test.jar test

    9.SOAP服务的发布   使用IE浏览器浏览http://localhost:8080/soap/admin/index.html,进入Deploy,填写如下信息:   ID: urn:test.math.sin   Scope: Request   Methods getSinValue   Provider Type: Java   Java Provider Provider Class:  test.SimpleMath   Java Provider Static: NO   确认发布,可以点List查看已发布服务!

    10.运行测试程序   a. cd c:/soaptest   b. java test.SimpleMathClien   应该可以看到返回的数值,则证明配置和测试成功,以后就可以发布自己的SOAP服务了!
