The bit before the colon is the epoch number. Try
rpmquery --qf '%{name}-%{epoch}:%{version}-%{release}.%{arch}.rpm\n' java-1.6.0-sun-compat
and (once you have jdk installed)
rpmquery --qf '%{name}-%{epoch}:%{version}-%{release}.%{arch}.rpm\n' jdk

Most packages have no epoch number, so you get
# rpmquery --qf '%{name}-%{epoch}:%{version}-%{release}.%{arch}.rpm\n' kernel
kernel-(none):2.6.18-128.1.16.el5.x86_64.rpm
