[R] rJava software

Hello,

it seems that rJava tries to detect the path to the Java Virtual Maschine
from a registry key which is not installed. I gues that the HLM means
HKEY_LOCAL_MASCHINE where you find normally the path to your installed Java.
On my Windows System i have for example the path
HKEY_LOCAL_MASCHINE\Software\JavaSoft\Java Runtime Environment\1.6.0_24
where you can find the key for the Java installation path.
Try to open regedit fromyour Windows console and convince yourself that the
path is not present.

Maybee a reinstallation of the JRE or JDK helps (for the registry key). Or
try to put your Java installation (the location) on the OS system path (open
the Windows Shell and type Java -version if a installation is already on the
system path), maybee that helps, too. 

Also, does it matter where java is installed?
Yes, it does matter because the OS has to find the executables and native
libs of the JRE and rJava has to find them, too because it relies on them.

I hope this helps.
