R help - Feb 2003 - [Out off-topic] SJava under Windows

Sorry for this off-topic subject.

I am fighting for running SJava under Windows.
SJava_0.64 (compiled by Simon Urbanek, thanks), R 1.6.2, Java JDK 1.4.0_02,
Windows XP pro:
> library(SJava)
> .JavaInit()
Error in .JavaInit() : Couldn't start Java Virtual Machine: Cannot find the
Omegahat interface manager class. Check you classpath!
> # And the second time...
> .JavaInit()
It gives the error: The instruction at "0x10bc9f0d" referenced memory
at
"0x10d60008". The memory could not be "read", and ejects me.

I have:
> .javaConfig
$classPath
[1]
"C:/PROGRA~1/R/rw1062/library/SJava/org/omegahat/Jars/Environment.jar"
[2] "C:/PROGRA~1/R/rw1062/library/SJava/org/.."

$libraryPath

Any idea?

Philippe,

I didn't use JDK 1.4 (and R1.6.2) yet, but may be I can help
you anyway:

- Did you add the directory that holds the jvm.dll to
  your PATH?

- If you take a look to the source of .JavaInit() ($R_HOME/
  library/SJava/R/SJava), there is a line:
    pathSeparator <- ifelse(version$os == "Win32", ";",
":")
  this should be:
    pathSeparator <- ifelse(version$os == "mingw32", ";",
":")
  All versions of R that I know of, return "mingw32" for version$os.

Best regards,
Heinz Grimm

For those who are interested, I posted a Windows compiled version of SJava
0.64 that works with R 1.6.2 and JDK 1.4 on ftp.sciviews.org, under
/Download/Rwindows/.


Thanks Simon, Heinz and Brian for helping me getting this running version.
When compiling SJava 0.64 under Windows (R 1.6.2, JDK 1.4.0-02, Win XP),
line 286 of $R_HOME/library/SJava/R/SJava has to be changed from:

   pathSeparator <- ifelse(version$os == "Win32", ";",
":")

to

   pathSeparator <- ifelse(.Platform$OS.type == "windows",
";", ":")

in order to work in R 1.6.2. Of course, the path to jvm.dll must also be
added to the "path" environment variable. With my installation, it is:

c:\progra~1\Java\j2re1.4.0_02\bin\Client
