Both were installed by SU Commands; I've used Synaptic to uninstall 29 but don't know whether it got rid of it all
Most probably you did.
jre-6u29-linux-i586-rpm.bin is a container for
jre-6u29-linux-i586-rpm and if you uninstalled that package with Synaptic you should be rid of this Java version -- except for the configuration files in
/home/<yourname>/.java. To be on the safe side I'd delete that folder or rename it to something else before installing
task-java with Synaptic. If you just rename it instead of deleting it you can restore its contents should it become necessary, which it probably won't.
(You could check if a number of Java folders exist and aren't empty, as for instance
/usr/lib/jvm, but I don't think it matters as any remaining ones probably will be overwritten when you install Java with synaptic. The same goes for any other
jvm-* folders under
/usr/lib. As your install is so new you shouldn't have to worry about any other
java-* folders under
/usr/lib.)
