Hello friends,
I compiled the c code and made a .dll file. Now I am trying to load it using the System.load(path); here path is the absolute path to .dll file I made using the JNI, but it is giving me an UnsatisfiedLinkError with many other things in the browser. To be honest I don't what it means except that UnsatisfiedLinkError. One more thing when I used the System.loadLibrary(name), here name is the name of the .dll that I am loading in my program with the .c, .java and .class all in the same directory it is running well and shows the desired output. Now I changed the directory of th e .dll file. Can any one tell me where I made mistake.

Hi Swapnil Sanghai,

Please CarefullyChooseOneForum. I doubt if this question is related with SCJP/OCPJP.

You can request forum moderator to move the post to appropriate forum, or wait till someone moves it. Please do not start another thread on different forum.

UnsatisfiedLinkError means that Java cannot find your DLL.

Define a system property named java.library.path that points to the directory that contains the DLL. You can do that on the command line with the -D option when you start your program, for example like this:

java -Djava.library.path=C:\MyProject\MyDllDir com.mypackage.MyProgram
