Set JAVA_HOME!  I am presuming that this is from my build, but you didn't
give the origin.  You probably also need to follow the rest of the
installation instructions in


The essence is

Sjava.zip -- unzip in ...\rw1062\library.  Having installed a Sun Java
JRE from java.sun.com (e.g. j2re-1_4_1_02-windows-i586-i.exe), you need to
set the environment variable JAVA_HOME to point to its top-level
directory.  The simplest way to so this is to create a file .Renviron
in either the working directory or your home directory (see the rw-FAQ)
and insert a line like

JAVA_HOME=c:/Program Files/Java/j2re1.4.1_02

For rw1070 you can (I believe) use install.packages to get the correct 
compiled version of SJava.zip, then set JAVA_HOME as above.
