Thank you for giving me the hint and for your very friendly help, I appreciate!! - True, true reading error messages in some case might be helpful.. Here is what I found out: In brief LD_LIBRARY_PATHS was not set up correctly. It has to be set to the path of the shared objects depending on where someone has installed the JDK. I installed it under /usr/local/java/current/ so for me that's: /usr/local/java/current/jre/lib/i386/ /usr/local/java/current/jre/lib/i386/client/ But this was not sufficient, R asked for another rJava.so so I had to add the following path, too (that's where I found the shared object using locate): /usr/local/lib/R/site-library/rJava/libs/ In conclusion this line did the job: #export LD_LIBRARY_PATH=/usr/local/java/current/jre/lib/i386/:/usr/local/java/current/jre/lib/i386/client/:/usr/local/lib/R/site-library/rJava/libs/ Now it runs smoothly! Nice! Best regards, Lothar PS: Some words on the official debian java packages: I can't consider if this still is the state of the art, but I could not find anything that it already has changed. Generally there might be some policy problems with SUN's Java packages and Debian. So the Debian packages (e.g. java-common) afaik are using Blackdown's Java implementations, in Java Version 1.4.2. But with a dummy package it is possible to do a workaround: http://www.debian.org/doc/manuals/debian-java-faq/ch11.html#s11.2 Thus afaik it is - at least - not always possible to resist only on the official .deb files for Java. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
