java7中DLL的调用方法

Question

From what I understood dll are not standardized. thus one cannot just call something in a dll. However I found this : http://johannburkard.de/software/nativecall/

This library allow you to call any method from a dll in java, so it seems that you can call any method in a dll. but it was done for 32 bit system, thus I cannot use it.

I have this dll, autohotkey.dll, I know there is the method "ahkExec" inside which take a String as parameter.

Is this really not possible to run it from java without using some kind of c++ magic?

Thanks.

ps : here is how it is done with nativeCall : https://gist.github.com/brigand/1526712

Answer 1

从1.0版开始，您就可以使用Java本机接口（JNI）来用Java调用DLL。

Answer 2

There is no magic in invoking external methods but you have to follow some rules based on what JNI provides .

If you need to use one function from library you could write a specific Wrapper-class like in this tutorial

For more tricky things better to work with SWIG
