Hello Ben,

I’d say that the .dll is not in the PATH and not in the working directory, or that something is wrong with it (like for example in my case).

It will help to do it without NetBeans, just run from the command line. That’s certainly possible in your environment.

Hi ,
I m a Phd student and actually, i have the same problem. just, im working wih netbeans, and it is forbidden to install any other software or any things. I m working on from 3 days and the delevered message is
“run: Exception in thread “main” java.lang.UnsatisfiedLinkError: HelloWorld.print()V
at HelloWorld.print(Native Method)
at HelloWorld.main(HelloWorld.java:4)
Java Result: 1
BUILD SUCCESSFUL (total time: 0 seconds)”

I m respecting all the steps, even i tried until now 5 examples and almost the same display error.
So do any one of u have an idea how to resolve this problem
NB: i m working with netbeans 6,9 and with jdk1.6.0_20

Danke

How to fix UnsatisfiedLinkError in JNI
I have never had problems with JNI. In the few situations when I needed it, it just worked…..

hello Franklin,

I’d say either the native binary is not found or it doesn’t contain what you need.

Did you compile it with gcc –add-stdcall-alias? Did you check out which functions the binary contains? Did it contain sendechotohost? Is it in the runtime PATH?

just need to build the helloworld.c following way

cl -I c:\Java\jdk1.6.0_01\include -I c:\Java\jdk1.6.0_01\include\win32 -LD HelloWorld.c -FeHelloWorld.dll

Not with -MD option. Java load library functions are not able to load because of -MD option. I think JNI documentations should be updated.

add option “-Wl,–kill-at”

`–kill-at’
Specifies that when `dlltool’ is creating the
exports file it should not append the string
`@ ‘. These numbers are called
ordinal numbers and they represent another
way of accessing the function in a DLL, other
than by name.

With this the problem will go away sure shot.

Wow !!
Thanks so much.

This topic helped me getting started with Java -> JNI -> DLL.

Thanks

Thanks Alexandra, your insight really works.
I got the same problem with Kai. I think it’s not about the procedure name. If you remove the “-MD” option when you link the C file, it can work.
