Dear community,
unfortunately I did not manage load the rJava package receiving the following
error-message:
library("rJava")
Error in inDL(x, as.logical(local), as.logical(now), ...) :
kann shared library 'C:/Programme/R/2.8.1/library/rJava/libs/rJava.dll' nicht
laden:
LoadLibrary failure: Das angegebene Modul wurde nicht gefunden.
Error : .onLoad in 'loadNamespace' für 'rJava' fehlgeschlagen
Fehler: Laden von Paket/Namensraum für 'rJava' fehlgeschlagen
Translation:
can't load library ... rJava.dll
LoadLibrary failure: the module was not found
That message comes from Windows, not R, and it's misleading. It does
not say that rJava.dll was not found, it says that a DLL needed by it is
not found. It would be helpful if it told you which one. You should
complain to Microsoft about it. If rJava.dll had been missing, the
English message would have been
shared library 'rJava' not found
The pedump utility (in the Rtools set, see
www.murdoch-sutherland.com/Rtools) can tell you what the dependencies are:
pedump -i rJava.dll
shows that it imports things from these dlls:
R.dll
KERNEL32.dll
msvcrt.dll
jvm.dll
The first 3 are routine; without those R wouldn't work. (Without
KERNEL32.dll, nothing in Windows would work.) So as Brian said, it's
likely jvm.dll that it can't find, or possibly a DLL that it depends on.
Did you install Java first, as rJava requires?

Reinstalling the package did not help, installing the latest developement
version didn't help as well.
The shared library rJava.dll is in place (exactly where R is looking for it)!
Are there any ideas, what's wrong.
I'd appreciate any kind of help very much, as I need rJava urgently to use
RWeka and iPlots.
Best regards,
Felix
