[R] Can't get R to recognize Java for rJava installation

[gparab]

I had similar issue. This worked for me:
get in as root:

export JAVA_HOME="/usr/java/jdk1.6.0_37/jre"
export PATH=$PATH:$JAVA_HOME/bin

ln -sf usr/java/default/bin/javah     /usr/bin/javah
ln -sf usr/java/default/bin/javap     /usr/bin/javap
(basically make sure you have all java* binaries that you have under
usr/java/default/bin/ are also under /usr/bin/ as link. Follow how javac is
placed under /usr/bin/)

R CMD javareconf

now make sure you still have the JAVA_HOME and PATH variable intact as you
set it. Go to R and try installing "rJava" package, it should work.
