How to connect R to Java?

Question

Java

Good afternoon. Can't connect JRI to Java. Environment:

• Windows XP 64
• R-3.1.1
• R_HOME is registered
• Java 1.7
• I connect jri_0.9-6 to IDEA

Rengine crashes on creation with the following 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-3.1.1\library\rJava\jri\jri.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform

jri.dll is in the folder.

Answer 1

The error appears to be that you are trying to load a 32bit dll inside a 64bit Java environment.
So it won't work.
Solutions:
1. Use a 32-bit Java environment for execution.
2. Use the 64-bit version of the jri.dll library.
