如何在C＃（或C ++）和JAVA之间进行通信

Question

i am working on a RFID based project in which we should communicate with Gates(RFID tag reader is called a GATE) through our application (and we are using java 2 ee to do this). the problem is the Gates are only shipping with c# and c++ SDK. what is your solution to communicate between c++ / C# and java? is there any so called convertor that can ease the pain? and this is the Gates manufacturer website if you need any more info : http://www.marktrace.com/en/default.html

thank you all.

Answer 1

You are searching for the Java native interface which allows you to communicate with other libraries.

You can either call methods from an external DLL and call Java methods from within your C++ code.

You can use jni4net to have a bridge to .NET libraries as well.
