概述

试图从Java调用C#编写的Web Service，借用了王咏刚的wsCaller源代码中DynamicInvoker类。
开始不清楚DynamicInvoker类的portName的含义，望文生义，以为是8080之类的端口号，实际上是下面wsdl中的wsdl:port 节点的“name”属性值“ReadWordSoap”：

wsdl提示：

提供Office文档的有选择性地读取文本服务.

需要特别引入的7个jar包如下所示：

Jar[/b]包[/b] [/b]	对应的库[/b] [/b]	用途[/b] [/b]
Axis.jar [/b]	org.apache.axis.* [/b]	[/b]
wsdl4j-1.5.1.jar [/b]	javax.wsdl.* [/b]	wsdl[/b]操作[/b] [/b]
jaxrpc.jar [/b]	javax.xml.rpc.* [/b]	xml.rpc [/b]
commons-discovery-0.2.jar [/b]	[/b]	discovery [/b]
log4j-1.2.11.jar [/b]	[/b]	Axis[/b]需要[/b]log4net [/b]
commons-logging.jar [/b]	[/b]	Axis[/b]需要[/b]LogFactory [/b]
saaj.jar [/b]	[/b]	引入[/b]SOAP [/b]

 

演示代码

请求一个C#编写的Web Service，利用DynamicInvoker类遍历web service每一个方法，获取serverName、参数列表以及类型。

代码演示：

import java.util.Map; import java.util.Vector; import java.util.Iterator; import java.util.Arrays;   import org.apache.axis.wsdl.symbolTable.*;   public class wsCaller {         /**        * @param args        */       public static void main(String[] args) {                       String wsdlLocation =             "http://192.168.1.113/ReadOffice/ReadWord.asmx?wsdl";            String serviceName = "ReadWord";         String operationName = "read";         String strFirstParam = "c://nlb.log";            String strSecondParam = "0";            String strThirdParam = "200";                 String portName = "ReadWordSoap";              /*             * 添加web service方法的输入参数到Vector             */            Vector parameterValues = new Vector();            parameterValues.addElement(strFirstParam);            parameterValues.addElement(strSecondParam);            parameterValues.addElement(strThirdParam);                       try            {               DynamicInvoker invoker = new DynamicInvoker(wsdlLocation);                                   /*                   * 遍历web service每一个方法，获取serverName、参数列表以及类型的过程                   */                  Vector vServices = invoker.enumServiceNames();                  Object[] Services = vServices.toArray();                  Arrays.sort(Services);                  for (int i = 0; i < Services.length; i++)                  {                       String strServiceName = (String) Services[i];                       System.out.println("ServiceName=" + serviceName);                                                                    Vector V = invoker.enumPortNames(strServiceName);                       String strPortName = (String) V.elementAt(0);                       System.out.println("PortName=" + strPortName);                                             V = invoker.enumOperationNames(strServiceName, strPortName);                       Object[] OperationNames = V.toArray();                       Arrays.sort(OperationNames);                       for (int j = 0; j < OperationNames.length; j++)                      {                             String strOperationName = (String) OperationNames[j];                             System.out.println("/t" + (String) OperationNames[j]);                             Parameters parameters = invoker.enumParameters(strServiceName, strPortName, strOperationName);                             Vector v = parameters.list;                             Vector vParameterValues = new Vector();                             for (int k = 0; k < v.size(); k++)                             {                                   Parameter para = (Parameter) v.elementAt(k);                                   System.out.print("/t/t" + para.getQName().getLocalPart());                                   if (para.getType().getQName().getLocalPart().equals("string"))                                   {                                        vParameterValues.addElement("asdasdas");                                   }                                  else                                  {                                         vParameterValues.addElement(null);                                  }                                  System.out.print("/t" + para.getType().getQName().getLocalPart());                                  System.out.println("/t" + invoker.getParameterModeString(para));                             }                     }                  }                    // 最后一个参数是调用web service的超时时间，这个原来是固化在类里面的 // 但其实应该暴露出来               Map map = invoker.invoke(serviceName,                             portName, operationName, parameterValues,                             new Integer(60 * 1000));                     // print result               System.out.println("Result:");               for (Iterator it = map.keySet().iterator(); it.hasNext();)                  {                   String name = (String) it.next();                       System.out.println(name + "=" + map.get(name));               }               System.out.println("/nDone!");            }            catch (Exception exc) {                  exc.printStackTrace();         }       }   }

 
最后输出的结果如下所示：
ServiceName=ReadWord
PortName=ReadWordSoap
    read
        >read>DocumentFilePath  string  [IN]
        >read>begin int [IN]
        >read>end   int [IN]
Result:
>readResponse>readResult=0018
