Hi Michael, > that is very odd, your javac does not understand -source and -target > parameters. can you try installing OpenJDK instead? I have java-1_6_0-openjdk installed. I also trried with java-1_7_0-openjdk, but that had the same result, so I switched backup to 1_6. Should I remove java-1_6_0-openjdk and try again? Winfried
