I constructed a java program using netbeans IDE that has ability to connect with a respective DLL; I want to connect and interchange data between my java program(.jar) and VSC++ program(.exe) through DLLs.JNI uses single Dll to invoke C/C++ function in native manner,In order to increase the efficiency I tried to connect and interchange primitive data types between Java program and C++ program using that DLL(JNI implemented).
Unfortunately C++ program cannot obtain data values that has been changed by Java Program.For example - If I declare a global int variable in DLL,java program can catch that int variable and can update it but If I run my C++ program(exe) loading same DLL simultaneously it cannot receive the updated value of that int variable declared in the DLL.
Therefore I need a solution to share/Interchange at least primitive data and their respective values between a JAVA and C++ Program using JNI (in spite of date transferring through Sockets).JAVA TO C/C++ & C/C++ to JAVA using DLLs.
(TWO WAY COMMUNICATION)
JAVA.jar <=> <JNI> <=> DLL <=>
[Connector Program C/C++] <=> C/C++ .exe
PLEASE HELP ME!! THANK YOU
