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?

------解决方案--------------------
没有用过。不过觉得还是JNI好!!
------解决方案--------------------
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;
