Hi,
I m trying to use smart card reader to read n write data to smart card. I have a dll file from the vendor which is for c++ and they have not used it for Java.
Is it possible to use the same dll for Java using JNI layer?

Please reply...

Problem is, that dll is for c++ . It does not contain functions that have same syntax required for java implementation.

That is why you need JNI to use the dll file.

I can not provide code - because I don't know that DLL, have never worked with and do not even know where that thingy belongs too. You will need a description of the DLL to connect to it with the JNI and will have to write the wrapper.

That is what we call software development.
Yes. Of course you have to write a JNI wrapper for the DLL.
