R help - Jul 2011 - Problem in installing rJava from source

Hi,

rJava depends on having appropriate version of Java installed.  You
can download the JDK from oracle for free at their website.  It should
automatically set the appropriate environment variables, but if you
are having difficulty with that still, you may need to set JAVA_HOME
to the directory where you installed Java.

Cheers,

Josh

P.S. Duncan Murdoch's Rtools gives you what you need to build R and
many packages but not all third party software a particular package
may depend on.

Hi all, I was trying to install rJava package (some older version) from
source. However could not achieve using "Rcmd  build -binary rJava"
syntax
with windows cmd. The building process stopped with following error:

 

ERROR*> JavaSoft\{JRE|JDK} can't open registry keys.

ERROR: cannot find Java Development Kit.

Please set JAVA_HOME to specify it's location normally 

ERROR: configuration failed for package 'rJava'

 

With this error it seems that, I need to install some additional tool(s),
however I have Duncan's Rtools installed. 

 

Can somebody through some light on this issue, what I should do with this
error?

 

Thanks,

If you cannot build a java program outside R then you won't be able to do so
inside R. Find a Java development resource (the JDK is one such) and get
command-line ability to compile java enabled, and then come back to interfacing
R with Java.
