# How to include JNI Symbols in your DLL

Firstly, use the magic pragma __declspec(dllexport). But this will cause compiler header mismatches between the header and the source files, unless you mangle both of them. (Ugly!)

Or otherwise, use the module-definition file:

LIBRARY MYLIB
EXPORTS
Java_com_my_package_ClassName_methodName0
Java_com_my_package_ClassName_methodName1
...
Java_com_my_package_ClassName_methodNameN


And invoke the linker with /def whatever.def as the command line argument.
