[R-SIG-Mac] About rJava

[Frédéric Dupont]

Hi,

Could somebody help me? I would like to install -- using R64 -- the rJava package.
I get an error message :

Make sure you have Java Development Kit installed and correctly registered in R.
If in doubt, re-run "R CMD javareconf" as root.

When I re-run 

sudo R CMD javareconf

I get :

Done.

Strangely enough (?) , there is no "Java library path".

Does anybody succeed in installing rJava source package? And, how ?

Sincerely,
