Can't update Java

I'm having a problem installing the java2.rpm on my 7.3-personal system. I want to install java2 so I can update to the latest Mozilla. When I try to install java2 it tells me I need to install the rpm unixodbc, which provides a required dependency. But after installing unixodbc, I still get an rpm error with java saying that the dependencies have not been met. Any ideas on what I might be missing? I'm sure I've installed all the required rpms but can't figure out why java2 still won't install.
