Typical error is of the form: file /etc/init.d/jexec from install of jdk-2000:1.7.0-ea.i586 conflicts with file from package jdk-2000:1.6.0_07-fcs.i586 In general it is of the form: file /etc/init.d/jexec from install of jdk-*1.7.0* conflicts with file from package jdk-*1.6.* The fix is to force the rpm to install despite the conflict.
