CAN Controller DLL with Java Application. Unable to open CAN port.

Question

I am creating a Java application that controls a Controller Area Network (CAN) controller via a vendor-supplied can.dll file.

can.dll contains a function bool openPort(DWORD memAddr) that allows the application to establish connection with the CAN controller.

I wrote a C++ test application, loaded can.dll via LoadLibrary and found this function to be working as it should, i.e. it returns true.

However, in my Java application, calling this via JNI or JNA returns false.

I hope someone can help me with this problem as I have been trying to fix this problem for more than a week.

Thanks :) JL

Answer 1

the problem is similar so I don't want to open a new issue .How can you write test application in java? Would you paste your code because i really need this.

Answer 2

I think you might want to look at sockets as an alternative or other IPC solutions.
