Folks,
Having problems getting started with SJava and request help.
I get this error when running .JavaInit() (within RGui 1.5.1, on Windows
2000):
Error in .JavaInit() : Couldn't start Java Virtual Machine: Cannot find
the Omegahat interface manager class. Check you classpath!
(Before you right back saying read the emails, please read further - in
short, been there, done that)
Environment:
RWin 1.5.1 (install from binaries)
OS Win 2000 SP3
jdk 1.4.0 (could this be it?? I saw requirement for 1.2 or 1.3 - I
wouldn't think this is the problem)
SJavaWin_0.62-8 binary
(. . . what else?)
Install procedure:
1. According to http://www.omegahat.org/RSJava/#Download,
cd $RHOME/library
unzip SJavaWin_0.62-8.zip
2. did that
3. got .Defunct error. email suggested changing SJava file in
{R_HOME}/library/SJava/R
4. did that
5. tried .JavaInit()
Attempts to solve problem:
1. Read the FAQ. Not much here on this one, although several emails
requesting help on this one, with no apparent solution.
2. Read the Archives. There were several emails concerning this, but
though one even said problem solved, but does not. It's a java classpath
problem, and not a LD_LIBRARY problem.
3. RTFM. Actually, the Howto.pdf dated 16 July 2002 (page 5), in fact
states:
"The default values in .javaConfig are computed and fixed when the R
library is installed These contain
the entries of the default classpath necessary to locate the classes
used to run the embedded Omegahat
interpreter and also the system properties that control how that
interpreter is created and behaves (e.g.
class names for components, etc.)." The other manuals don't seem to
cover the
a. Tried setting a reasonable classpath, in my case
C:/R/rw1051/library/SJava in a CLASSPATH environment variable. java
should be able to find the
org.omegahat.Interfaces.NativeInterface.OmegaInterfaceManager. However I
noticed on the SJava file, in the javaConfig assignment, the
expression if(nchar(tmp) > 0)
classPath <- strsplit(tmp,":")[[1]]
}
" which seems to split based on a unix environment and not a windows.
Realizing I *shouldn't* need this just to see if things will run, took
out my CLASSPATH (after trying other various settings).
b. Tried modifying the SJava file where the default$classPath is set.
4. Uninstalled by deleting the library/SJava directory and started over.
Any help would be greatly appreciated. Also willing to be a guinea pig
for the windows stuff. Haven't tried a install from source. My next step
if I haven't really mucked things up.
thanx
steve
novice R user, but plenty of java

The URI you quote says SJavaWin 0.62-8 is for R 1.3.1 (which is a year old). The current version of SJava is 0.65-0. I don't think you can run 0.62-8 on later versions of R. BTW, there are separate email lists for the Omegahat packages on www.omegahat.org which look to me to be more appropriate. On Wed, 28 Aug 2002, Stephen C.

Check you classpath!One workaround I have had some success with is to set the working directory to the directory containing the Omegahat dll before running .JavaInit(). -thomas> (Before you right back saying read the emails, please read further - in > short, been there, done that) > > Environment: > RWin 1.5.1 (install from binaries) > OS Win 2000 SP3 > jdk 1.4.0 (could this be it??

Hello, Stephen,
I encountered this problem before. Here is my short time fix, please let
me know if you find something better.
Thanks again, Dr. Rossini, for your quick response.
I tried pathSeparator <- ";" and then .JavaInit(), but it did not
work, I
guess because the pathSeparator statement overrode mine.
But, thanks for the idea, I tried version$os <- "Win32" and it
worked.

How about:
pathSeparator <- ";"
