how to add customized rpm package in kickcstart's %package ,not in the %post

[liqin]

As what I said in the title,I am trying to install Fedora 9 with the kickstart.I can't figure out how to add the rpm package in the %package section of the kickstart.If I add one my own customized rpm package "myown" and I put the myown-1.0.0.rpm under Package directory.What else can I change?
Is it the xml files under repodata files such as Fedora-9-comps.xml.gz and primary.xml.gz.
I am not very sure about the format how to edit it.After I add the myown into Fedora-9-comps.xml.gz and primary.xml.gz.I got the error like "unable to read group information from repositories,This is a problem with the generaton of yor install tree".

Anyone has some idea about it.I really appreciate!!Thanks!


The following is my kickstart file
