<p style=line-height: 150%>如果大家用过微软的SoapToolBox的话，一定会知道部署一个访问COM对象的WebService是非常简单事情。而在java环境下，要完成这件事情也不是很复杂。以下是我通过WebService访问一个简单COM对象，只包含一个简单的SayHello方法返回字符串。

<p style=line-height: 150%>我的环境是tomcat4.0+apachesoap,其中tomcat在http://jakarta.apache.org/site/binindex.html

下载，apachesoap在http://xml.apache.org/dist/soap/下载。

步骤：

1。把soap.jar包含到classpath

2。把COMProvider.dll所在路径设置到Path

3。VB写一个COM对象代码如下

‘WebDll.SimpleMath

Public Function SayHello() As String

SayHello = "Hello From Com Object"

End Function

编译生成WebDll.dll

4。写一个部署描述文件WebDll.xml

<!--Apache SOAP specific deployment descriptor (ie loads this service into Apache SOAP.-->

<isd:service xmlns:isd="http://xml.apache.org/xml-soap/deployment"

id="urn:WebDll-COM">

<isd:provider type="org.apache.soap.providers.com.RPCProvider"

scope="Application"

methods="SayHello">

<isd:java class="required not needed for COMProvider"/>

<isd:option key="progid" value="WebDll.SimpleMath" />

</isd:provider>

<isd:faultListener>org.apache.soap.server.DOMFaultListener</isd:faultListener>

</isd:service>

5。部署

java org.apache.soap.server.ServiceManagerClient http://localhost:8080/soap/servlet/rpcrouter deploy WebDll.xml

6。客户端程序

import java.io.*;

import java.net.*;

import java.util.*;

import org.apache.soap.*;

import org.apache.soap.rpc.*;

public class JClient

{

public static void main( String[] args) throws Exception

{

Integer n1=null;

Integer n2=null;

final String urn= "urn:WebDll-COM";

Vector params = new Vector ();

URL url = new URL ("http://" + serverhost + ":" + serverport+ soapservlet);

// Build the call.

Call call = new Call ();

call.setTargetObjectURI (urn);

call.setMethodName ("SayHello");

call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);

call.setParams (params);

Response resp = call.invoke (/* router URL */ url, /* actionURI */ "" );

if (resp.generatedFault ()) {

Fault fault = resp.getFault ();

System.out.println ("Ouch, the call failed: ");

System.out.println (" Fault Code = " + fault.getFaultCode ());

System.out.println (" Fault String = " + fault.getFaultString ());

} else {

Parameter result = resp.getReturnValue ();

System.out.println(result.getValue());

}

}

static String serverhost= "localhost";

static String serverport= "8080";

static String soapservlet= "/soap/servlet/rpcrouter";

} // end addit

7。测试运行

编译JClient启动Tomcat

运行java JClient

返回结果

Hello From Com Object
