I want to use dll in my java program. I saw that we want to use __declspec(dllexport) to export my function in dll. Do we also want this while exporting using jniexport for java? I am using mingw compiler?

Whether jniexport itself enough or i want to use __declspec(dllexport) to export my function into library – Sri vishnu Bharat Feb 08 '18 at 13:55

No, you need to wrap your dll call and use the JNIEXPORT-macro from the native-interface in Java.
The __declspec(dllexport) extension is a Microsoft-specific extension used in the VS-compiler to automatically export / import functions and classes/methods to dll's.

Thankyou for your answer. Can i use the following function? JNIExport int JNICall java_Main_add (int a,int b){} is it enough. – Sri vishnu Bharat Feb 08 '18 at 14:16

Yes, normally this shall be enought. And you need to load the wrapper package into your application. – KimKulling Feb 08 '18 at 14:17
