有关于JCOM组件的有关问题

有关于JCOM组件的问题
最近在学习用Java调用COM组件的事情，在论坛上找到某大虾的帖子：
http://topic.csdn.net/u/20090516/15/f21ec850-bc4c-4ab4-bb1c-bc9b95769395.html

我也根据他的例子做了，但是貌似有问题，贴上代码

Java code

import jp.ne.so_net.ga2.no_ji.jcom.IDispatch;import jp.ne.so_net.ga2.no_ji.jcom.ReleaseManager;public class CallDll {    public static void main(String[] args) {        Process();    }    public static String Process() {        ReleaseManager rm = new ReleaseManager();        try {            IDispatch vbcom = new IDispatch(rm, "U8Distribute.iDistribute");            Object[] param = new Object[] { "XXXXX" };            String strRet = (String) vbcom.method("Process", param);            System.out.println("return: " + strRet);        } catch (Exception e) {            e.printStackTrace();        } finally {            rm.release();        }        return null;    }}

出现了异常：

Java code

jp.ne.so_net.ga2.no_ji.jcom.JComException: createInstance() failed HRESULT=0x800401F3L    at jp.ne.so_net.ga2.no_ji.jcom.IDispatch._create(Native Method)    at jp.ne.so_net.ga2.no_ji.jcom.IDispatch.create(IDispatch.java:84)    at jp.ne.so_net.ga2.no_ji.jcom.IDispatch.<init>(IDispatch.java:46)    at com.dcec.call.dll.CallDll.Process(CallDll.java:14)    at com.dcec.call.dll.CallDll.main(CallDll.java:8)

论坛里也有人遇到这样的错误，他只是说接口写错了便没了下文。
希望哪位大虾懂JCOM的指点小弟一二，搜了一天的资料了，还是没个头绪，脑子乱的紧。。。



PS：Java调用组件是用JNI好，还是用JCOM好？

[解决办法]
没有用过。不过觉得还是JNI好！！
[解决办法]

Java code

ReleaseManager rm = new ReleaseManager();        String res = null;        try {            IDispatch vbcom;            vbcom = new IDispatch(rm, "U8Distribute.iDistribute");            Object[] param = new Object[] { *** };            res = (String) vbcom.method("Process", param);        } catch (JComException e) {            e.printStackTrace();            throw new Exception("Jcom调用发生异常" + e.getMessage());        } finally {            rm.release();        }        return res;
