install the SJava package on unix
Hi Xavier. The error message suggests that in loading SJava.so, the loader cannot find the core Java library libjvm.so which is provided by in your Java installation (JDK). Usually this is not installed somewhere standard on your system and so, as you correctly surmized, you must explicitly have the directory in your LD_LIBRARY_PATH. The scripts RJava.bsh or RJava.csh that are installed with the SJava package in the in the scripts/ directory of the package attempt to get the correct values and will work for most JDKs. So before starting R, execute . <wherever>/SJava/scripts/RJava.bsh or for csh and tcsh shells source <wherever>/SJava/scripts/RJava.csh and that will hopefully fix the proble. Otherwise, find where libjvm.so (and other libraries on which it depends (e.g. libhpi.so)) and manually add those directories to LD_LIBRARY_PATH. Hope this works. D.

Hi,
I've got a problem to use the SJava package with R.
I have a SUN solaris 8 machine.
Then I did R INSTALL -c SJava_0.65-0.tar.gz
without problem
Now I try the test provided on the web site:
library(SJava)
and here I receive the error message:
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library
"/usr/local/lib/R/library/SJava/libs/SJava.so":
ld.so.1: /usr/local/lib/R/bin/R.bin: fatal: libjvm.so: open failed: No

Error in library(SJava) : .First.lib failed
The result of the command
java -version
java version "1.2.2"
Solaris VM (build Solaris_JDK_1.2.2_08, native threads, sunwjit)
The LD_LIBRARY_PATH is
Sys.getenv("LD_LIBRAYRY_PATH")
LD_LIBRARY_PATH

Could you please help me?
Thanks
Xavier
