Cannot load rJava because cannot load a shared library

Question

I have been struggling to load the rJava package in R.

I get the following messages

> library(rJava)
Error in inDL(x, as.logical(local), as.logic         


        

Answer 1

For what it's worth, putting C:\Program Files\Java\jre6\bin\[server] in my PATH worked for me. It seems the rJava module could jot find jvm.dll there.

Here are the versions of R and Java that I'm using (on 64-bit Windows 7).

Java:

java version "1.6.0_30"
Java(TM) SE Runtime Environment (build 1.6.0_30-b12)
Java HotSpot(TM) 64-Bit Server VM (build 20.5-b03, mixed mode)

R:

R version 2.14.1 (2011-12-22)

Platform: x86_64-pc-mingw32/x64 (64-bit)
