How to Debug JNI dll using OD?

[winndy]

JEXECreator launch the jexecpm.jar(java) through jexecpm.exe(C++).
And jexecreator.dll is a dll using the JNI method.
I loaded the jexecpm.exe,but when I view the internal moduls,I
cannot see the jexecreator.dll.
I loaded jexecreator.dll and try to attach jexecpm.exe,but it failed.

Is there any way to debug JNi dll?

Hi,I read LoadDll tut from hxxp://www.ollydbg.de/.
And I can debug the dll.
I didn't fill the arguments .
Fortunately,I can debug it also.
But I don't know the reason.
And the dll uses standard MD5 ,But It's hard to write a keygen,
Because it needs brute force.
Anyhow,I patch the dll.And It works.
