*Sigh* This is part of the reason I hate pre-packaged apps.
Ok, it looks like you've got a half-installed Apache. So, your options are to install the rest of it OR build it from source to make sure you have everything.
First, confirm the version of Apache you're running:
$ /usr/sbin/httpd -V
and post the output here. Then you should see what httpd packages are available for FC5. Don't worry about which one(s) you'll need yet, just get the list.
Then we can go from there.
Without APXS, you won't be able to build mod_jk2 as a DSO (shared Apache module) and I'm not sure what your options will be if you can't get mod_jk2 built as a DSO for your Apache version. Maybe a pre-built one could be downloaded.
Also, see if there are any Tomcat packages for FC5 and/or any mod_jk2 packages for FC5.
I'm gone for the evening.
Peace...
