R help - Jun 2011 - XLConnect Error

Any ideas of what is happening when I attempt to load XLConnect? I think I
installed everything correctly. I posted what I get when I installed rJava
as well as when I attempted to load rJava directly. Thanks in advance for
any help you can give on this. 

library(XLConnect)
Loading required package: XLConnectJars
Loading required package: rJava
Error : .onLoad failed in loadNamespace() for 'rJava', details:
  call: fun(...)
  error: JAVA_HOME cannot be found from the Registry
Error: package 'rJava' could not be loaded

This is the mesage I get when I install rjava:

Installing package(s) into ?C:/Users/550062/Documents/R/win-library/2.13?
(as ?lib? is unspecified)
trying URL
'http://cran.opensourceresources.org/bin/windows/contrib/2.13/rJava_0.9-0.zip'
Content type 'application/zip' length 654181 bytes (638 Kb)
opened URL
downloaded 638 Kb

package 'rJava' successfully unpacked and MD5 sums checked

The downloaded packages are in
	C:\Users\550062\AppData\Local\Temp\RtmppIjwgg\downloaded_packages

If I try loading rJava directly I get the samer error as XLConnect:
> library(rJava)
Error : .onLoad failed in loadNamespace() for 'rJava', details:
  call: fun(...)
  error: JAVA_HOME cannot be found from the Registry
Error: package/namespace load failed for 'rJava

Obvious question is: Do you have Java installed? Is this 32- or 64-bit 
R? And Java? The other output suggests we are talking about Windows 7 as 
the OS?

Hi,
I am having the same issue as described by the original subscriber....  

can you offer any guidance on how to install Java ???  Do I need to do this
from the R command line ???

or do I need to do this outside of the application??


Thanks

Daniel

Hi Daniel,

you can get Java from http://www.java.com/en/download/manual.jsp?locale=en
Simply download and follow the instructions.
Hope that helps.
