首先谢谢了，这是转word的，我现在要用到另外一个DLL, 用jacob怎么来调用里面的方法：
比如，demo.dll里面有个方法 createFile()；我怎么通过jacob 在其他的java类中调用这个方法。
最好有实际的例子。拜托了……Top

其它jacob是基于事件方式进行word处理的。如果像楼主所说，必需修改jacob的源代码：java和.h都需要修改--重新用javah生成.h。Top

"通过jacob 在其他的java类中调用这个方法。"?不是很明白这句话。
如果是在java中调用"另外一个DLL"那就好办--用JNI生成一个单独的DLL，用JNI生成的dll调用“另外一个DLL”。
如果是jacrob调用"另外一个DLL"就不好办了。Top

test.cls文件内容如下：
Public Function myAdd(i1 As Variant, i2 As Variant) As Variant
myAdd = i1 + i2
End Function
注：我生成的是mytest.dll,并且这个dll一定要注册！
---------------------------
java文件调用如下：
public static void main(String[] args)
{
System.runFinalizersOnExit(true);
Dispatch test = new Dispatch("mytest.test");
//下面打印“8”
System.out.println(Dispatch.call(test, "myAdd", new Variant(3), new Variant(5)));
