Dear All. I was trying to connect java and R using jri but i have received some errors. Operating system - windows7, Java version = java 1.6.0_23, R version = R 2.12.1. JAVA_HOME and R_HOME variables are set in user variables and system variables. I have also added JRI .jar path in the system variable. Could you please suggest any solution? 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:\Windows\System32\jri.dll: Can't find dependent libraries at java.lang.ClassLoader$NativeLibrary.load(*Native Method*) at java.lang.ClassLoader.loadLibrary0(Unknown Source) at java.lang.ClassLoader.loadLibrary(Unknown Source) at java.lang.Runtime.loadLibrary0(Unknown Source) at java.lang.System.loadLibrary(Unknown Source) at org.rosuda.JRI.Rengine.<clinit>(*Rengine.java:19*) at rtest2.main(*rtest2.java:72*) Thanks In advance Kind Regards W.
