Quick caveat: I am not a Java user or programmer. That said, I had wanted to get this work for years because several interesting packages build on-top of rjava. And as of a few years ago it started to work so I since then I am a) instrumenting Debian's r-base-core package to be Java-aware b) packaging /maintaining rjava for Debian as well but all of that only with the non-Sun packages. E.g. rjava has a build-depends on openjdk-6-jdk, and that seems to work. So start by installing that. I have also built JGR and other packages, and have the cran2deb robot build quite a few more. But never with the Sun java, and certainly never when mixing. Beyond that, maybe the Java lists can be of more help than we can here. -- Regards, Dirk _______________________________________________ R-SIG-Debian mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-debian
