can't load rJava in R 2.8.1 on Windows XP

If you look at rJava:::.onLoad now that you can load the package, 
you'll see that it goes through a number of tests to try to find the 
right path. 
Slightly different for me, but failure: 

jvm.dll is on path (checked successfully with "where jvm.dll")
From within R?  Remember that the PATH is process-specific.  Maybe your 
shell added something that put jvm.dll on its path, but you didn't start 
Rgui from there.

In any case, looking at the .onLoad, it appears the easiest thing to do 
is to define the environment variable JAVA_HOME.  The startup code puts 
$JAVA_HOME/bin, $JAVA_HOME/bin/client, and $JAVA_HOME/jre/bin/client 
onto the end of the path, so things should work if at least one of those 
has your jvm.dll in it.

Rgui: Dialog Box (Translated from German)

R Console: RGui.exe Component not found

The application could not be started because jvm.dll could not be found.
