[…] fixed the method names in mylib.dll, as suggested here. The method names had somehow gotten mangled by the compiler, but I added linker flags and the dll […]

All thanks to you, i am able to run my first jni java after 11 years working in java & i used to give up in between and never used to work so hard to look for solution and used to stick with java alone.

Thanks to you solution

I have a probable solution for anyone getting this error when working with Eclipse! If you are loading your dll file as a resource into your system classloader, then you absolutely must do a project–>clean every single time you update your dll!! Even restarting eclipse or your computer won’t clear the old dll resource from your classloader. Tracking that one down was incredibly painful!

Idk if this will help anyone, but I’m using C++ compiling with VS win64 2010 command prompt.
I used the -MD option suggested fix and it did not affect my link problem.
I since my code was written in C++ I had modified my JNI header file code and removed this code:
“#ifdef __cplusplus
extern “C” {
#endif

//Method prototypes

#ifdef __cplusplus
}
#endif”
Obviously I’m not very clever. Once I put this code back in and ran the dumpbin tool (thanks to whoever mentioned that first) I got a perfect looking signatures.
This solved my linking issue.

Thanks for all the members in this post….
If you are using gcc complier, then add “-Wl,-kill-at” as one of the argument to gcc, This will solve the problem.
So, for example, in my case the command looks like this
“-Wl,-kill-at” -shared HelloWorld.c “-Ic:\Program Files\Java\jdk1.6.0_02\include” “-Ic:\Program Files\Java\jdk1.6.0_02\include\win32” -o ${workspace_loc:/JNISampleJava/bin}\HelloWorld.dll
