R help - Aug 2011 - rJava on Debian squeeze (or other versions of Linux)?

Has anyone successfully installed rJava on Debian squeeze (or any other 
version of linux)?

I keep getting the

    ... (JDK) is missing or not registered in R


error message when installing the package.

I've tried running 'R CMD javareconf', setting JAVA_HOME and editing
/etc/R/ldpaths by hand, but to no avail.

The problem might be related to the R_JAVA_LD_LIBRARY_PATH that's set in 
/etc/R/ldpaths.  Does anyone know what it's supposed to contain?  I 
haven't been able to find any documentation on it?

Searching the web, I've found many references to this problem, but no 
solutions.

thanks,

bw

a) Did you try 'sudo apt-get install r-cran-rjava'  ?  This is after all
   packaged in Debian

b) The Debian rjava package has 'openjdk-6-jdk' in its Build-Depends, do
you
   have that installed if you try to build from source?

c) Next time please post on r-sig-debian.

^ I mean:
(i) Install Java from Oracle
(ii) run R CMD javareconf if necessary
(iii) Install the rJava package from within R, i.e. 
install.package("rJava", ...)

I'm trying to avoid using the Debian specific
package.

I've tried setting $JAVA_HOME to all all sorts of things without
success.
