Subject: using a dll in a webapp
> Hi everybody,
>
> I want to establish a connection to a serial port from my webapp by
> using the javax.comm package which uses the win32com.dll (on windows
> systems).
>
> In most cases, it seems to be the common way to place the dll in the
> <jre>/bin directory. But I want to have all needed libraries in my
> webapp directory.
>
> Therefore, I resolve the path of the dll in my webapp:
> String win32com = new
> File(this.getClass().getClassLoader().getResource("win32com.dll").toURI()).getPath();
>
> Now, I add the path to the java.library.path property:
> System.setProperty("java.library.path",
> System.getProperty("java.library.path") + File.pathSeparator + win32com);
>
> When I now output the java.library.path on the console (using
> System.getProperty("java.library.path")) the dll is in the path.
>
> Now, I try to load the dll:
> System.loadLibrary("win32com.dll");
>
> And this fails. The Error message is:
> java.lang.UnsatisfiedLinkError: no win32com.dll in java.library.path
>
> I wonder how it's possible that the dll seems not to be in the
> java.library.path although I just added it - has anybody an idea?
>
> Thanks a lot for helping.
