[R] How to get JRI to work from my NetBeans

Did you set a system property for java.libary.path that points to the
native library as the error message instructs?

I'm not familiar with NetBeans, but in Eclipse you can set the JVM
properties in a dialog. Otherwise you can always pass it in via the
command line: -Djava.library.path=<path to the JRI library>

Subject: [R] How to get JRI to work from my NetBeans

I need your help. I have downloaded a precompiled JRI as part of rJava.
have included rJava as part of my R package libraries.
Now I need to be able to work with some R functions from my Java apps.
using NetBeans on Windows.

I have followed some instructions from http://www.rforge.net/JRI/
but i keep on getting errors when compiling my Java app as follows:

Cannot find JRI native library!
Please make sure that the JRI native library is in a directory listed in

java.lang.UnsatisfiedLinkError: no jri in java.library.path
        at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1709)
        at java.lang.Runtime.loadLibrary0(Runtime.java:823)
        at java.lang.System.loadLibrary(System.java:1030)
        at org.rosuda.JRI.Rengine.<clinit>(Rengine.java:9)
        at rtest.main(rtest.java:61)
Java Result: 1

Can anyone help me with detailed steps to solve the problem? Thanks.
