Error loading jni from java.

Access Violation error with various causes.

In this case, you usually use a window-side debugger to find the cause.

If you have a source on the dll side, you can use VC to debug it, and if you don't, try debugging it with a binary debugger such as windbg and ollydbg.

If it doesn't work, please send the dll you worked on and the source you worked on to my mail ([email protected]).
