Slightly different for me, but failure:

From within R? Remember that the PATH is process-specific. Maybe your
shell added something that put jvm.dll on its path, but you didn't start
Rgui from there.
In any case, looking at the .onLoad, it appears the easiest thing to do
is to define the environment variable JAVA_HOME. The startup code puts
$JAVA_HOME/bin, $JAVA_HOME/bin/client, and $JAVA_HOME/jre/bin/client
onto the end of the path, so things should work if at least one of those
has your jvm.dll in it.
JAVA_HOME had been defined (that's how I started, after reading the c code).
In RGui
shell("where jvm.dll")
C:\Program Files\Java\jre6\bin\client\jvm.dll
shell("set JAVA_HOME")
JAVA_HOME=C:\Program Files\Java\jre6
That doesn't last beyond the shell call, as far as I know. It starts a
process to run the shell, sets the environment variable in that process,
then the process dies and the setting dies with it. If you want a
permanent setting, you should set it in the Rgui process, via Sys.setenv().

And yet : the dialog box as mentioned, and, after clicking Ok:
Error in inDL(x, as.logical(local), as.logical(now), ...) :
unable to load shared library
'C:/PROGRA~1/R/R-28~1.0/library/rJava/libs/rJava.dll':
LoadLibrary failure: Das angegebene Modul wurde nicht gefunden.
Error : .onLoad failed in 'loadNamespace' for 'rJava'
Error: package/namespace load failed for 'rJava'
If it matters: same problem from Rterm. To be sure it is not a security
problem under Vista, I also run both RGui and Rterm as admin. Same.
