how to use dll (written in C) in Java application?

[DeepThinking]

Hi, I have a Frame_Grabber.dll written in C.
How can I use this DLL in my java application?

I know how to use java native interface, and to create my own dll, but what if the dll already exists?

Does someone know it?

What you would have to do is write a wrapper JNI DLL that will forward your java calls to the legacy DLL.
Look into JNI.
