Unable to install rjava package in ubuntu, R version is 3.1. jdk i.7 installed. please share the exact path of java configuration for R. I have already tried javareconf - e to set the env for rjava.
Below is the output after rJava installation.

I have answered that question here before -- just do
sudo apt-get install r-cran-rjava
as this is a maintained package within the distribution.
If that fails, please let me know, preferably via a proper (Debian) bug report as I happen to be the maintainer of both the R package and this rJava add-on.
