I want with a java programm to call functions from a dll in c.
Alexander Krapf Dear Stephane,Good luck,
you have a couple of problems in your approach. Let me address them in sequence:
- You cannot call directly into your DLL. You need to wrap your DLL with a DLL that you build. That DLL will need to implement the native methods that you declare by delegating to the methods in your target DLL.
- String objects are immutable in Java. This means that the outbuf argument must not be a String. You can make it a StringHolder (a class that has a String field that you set with the result) or a character array which you convert to a String.
- You need to be careful with the encoding that is used when you extract bytes from the Java input string. The default encoding might not be the correct one.
