integrating R programming with java

Question

I'm Trying to perform Example-1 From Rjava folder, I have Installed JRI.jar,JAREngine.jar, REngine.jar in my Libraries in netbeans,and also given a these 3 path to user and System variable:C:\Program Files\R\R-3.3.1\library\rJava\jri\i386;C:\Program Files\R\R-3.3.1\library\rJava\jri\x64;C:\Program Files\R\R-3.3.1\library\rJava\jri;

System : Both 32/64bit R is installed and accessed.

But it is Showing me Error message :

Error:
Cannot find JRI native library!
Please make sure that the JRI native library is in a directory listed in java.library.path.

java.lang.UnsatisfiedLinkError: C:\Program Files\R\R-3.3.1\library\rJava\jri\i386\jri.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform

If you're running 64-bit R, you have to install 64-bit Java as well. — Hong Ooi

jar file is one thing, java executable is another. What does java -version report as the current version/bit-ness? — r2evans
