java - Convert static windows library to dll

Question

I have a library contains a bunch of static *lib files, I wish to access them from JNA (a Java library that allows one to dynamically call `dll's from JAVA Code), so is there a way to magically change static lib to dll?

Code was compiled using Visual studio (hope that is relevant), and I also have appropriate header files.

I do not have access to source code, also I would like to do it using only free (as in beer) tools.

I'm not aware of anyb tools that will do this automatically, but the process is to create a DLL project and add your libraries to the project. For each function in the header file:

int SomeLibFunc( int x, int y );

you would need to create and export your own function in the DLL;

int MyFunc( int x, int y ) {
   return SomLibFunc( x, y );
}

The process is quite mechanical, and you may be able to knock up a script using something like perl to create the DLL source files.
