Entry point not found for js32.dll

Question

Dear Friends,
I am trying to connect to a Domino server using NRPC (Native call based) connection. I have added Notes Client path in PATH variable (double checked this). My machine is W2k and Java version 1.4.2.
The following is the code which I am trying to run and getting erorr as,
"The procedure entry point JS_NewStringCopyN could not be located in dynamic link library js32.dll". I've use Dependency walker tool to ensure that js32.dll contains the specified function. May I know what's going wrong here?
Thanks,
Ketan

Hi,
Can you try with a Generic Wrapper like JNative (it contains a method to list all exported functions of a dll : even mangled ones) ?
