I was able to get it to work using .jinit .jaddClassPath("../lib/jarFileHere.jar") but the rJava docs explicitly says not to use .jinit because it won't work when the code is used as a package.

I am trying to load 'rJava' package in my Unix machine. Before loading I have set the path using Sys.setenv("JAVA_HOME= myfilepath") in my R script.

I'm using RStudio on and Ubuntu box (14.04) and I tried to upgrade rJava from sources and in the process I managed to lose it. I tried to install it again using, install.packages("rJava") which returned the following error message, configure: error: One or more Java configuration variables are not set. Make sure R is configured with full Java support (including JDK). Run R CMD javareconf as root to add Java support to R. If you don't have root privileges, run R CMD javareconf -e

I have followed guides on the web and looked at questions on stackoverflow but I am still not able to set up JRI on Windows.

I'm trying to use R to hook the Java code from the GSRad project. The GSRad Java code is available online and comes as a One-Jar project jar (I was not familiar with One-Jar until today). I can run the One-Jar file just dandy using the following command (after unzipping the file from the above link): java -jar gsrad_sample.jar When I pop open the gsrad_sample.jar file I see a jar titled clima_GSRAD-1.0.0.jar in the /lib/ directory which contains the class files I want to hook with R.
