Try the following:
as super-user
java-config -L
java-config -S (put a number pointing to sun-jdk-1.6)
R CMD javareconf
export JAVA_HOME=/usr/lib/jvm/sun-jdk-1.6/jre
export R_JAVA_LD_LIBRARY_PATH=${JAVA_HOME}/lib/amd64/server:
${JAVA_HOME}/lib/amd64:
${JAVA_HOME}/../lib/amd64::/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib
start R
install.packages("rJava")
install.packages("JGR")
then as a normal user
C_NUMERIC=C
export LC_NUMERIC
/usr/lib/jvm/sun-jdk-1.6/jre/bin/java -Xmx512m -Djgr.load.pkgs=yes
-Djgr.loader.ver="${JGR_LOADER_VER}" -Djava.library.path=".:
${LD_LIBRARY_PATH}" -classpath "/usr/lib64/R/library/rJava/java/boot"
-Drjava.path="/usr/lib64/R/library/rJava"
-Drjava.class.path="/usr/lib64/R/library/rJava/jri/JRI.jar:/usr/lib64/R/library/iplots/java/iplots.jar:/usr/lib64/R/library/JGR/java/JGR.jar"
-Dmain.class=org.rosuda.JGR.JGR RJavaClassLoader $*
library(JGR)
JGR()
This got JGR started on my computer. I still have problems with
dyn.load.
Best regards
