rJava problems

Dear R Users
Have run into a problem with the rJava package recently. I do not seem 
to be able to load the package. I am on R 3.0.2 and updated the rJava 
package this morning from the Pennsylvania mirrors. I get the 
following error:

----
package ?mnormt? successfully unpacked and MD5 sums checked
package ?rJava? successfully unpacked and MD5 sums checked

The downloaded binary packages are in
C:\Users\t_uzu_000\AppData\Local\Temp\RtmpOC9zec\downloaded_packages

library(rJava)

Error in get(Info[i, 1], envir = env) :
cannot allocate memory block of size 2.8 Gb
Error: package or namespace load failed for ?rJava?

----

Any pointers ?

Thanks in advance

A small follow-on to this: I uninstalled the package, restarted my 
machine, and reinstalled the package. Now, when I try and load the 
package, I get an entirely different error message: 

 > library("rJava") 

Error : .onLoad failed in loadNamespace() for 'rJava', details: 
   call: inDL(x, as.logical(local), as.logical(now), ...) 
   error: unable to load shared object 
'C:/Users/t_uzu_000/Documents/R/win-library/3.0/rJava/libs/i386/rJava.dll': 

   LoadLibrary failure:  %1 is not a valid Win32 application. 

Error: package or namespace load failed for ?rJava? 

Any thoughts appreciated. 

Kind regards

You don't really provide enough information like
R.Version()

but my guess is that you are running 64-bit R either directly or through R Studio but that you have only 32-bit Java installed.   I am doing fine on Windows with Java 7 update 45 but had some 64-bit run issues with only Java 7 update 40 64-bit JDK.

HTH,
Rob
