Apache 2 httpd.conf empty

Hi everybody,
I have installed Apache 2 + Tomcat 5.5. on Ubuntu 7.04 and the default httpd.conf is empty (0 lines), however there is a file called apache2.conf that looks like a default httpd.conf.
I didn't use Apache in ages, since 1.3.x release, but I remember that the httpd.conf by default wasn't blank.
Apache was downloaded directly from the Ubuntu package manager, so far the exactly same problem happen on two machines.

I am not very familiar with Tomcat, maybe this has something to do with the fact that the httpd.conf is blank?

The Debian and hence Ubuntu apache2 used apache2.cond, not httpd.conf.

OK, thanks for the explanation
