How do I install Apache Tomcat 7.0.x on Yosemite?

I am a junior-level developer beginning to work on a project that requires me to use Apache 7.0.x, and I'm running Yosemite with a Windows 7 VM. When I did some research on how to get Apache, I discovered that Mac comes with Apache pre-installed. However, it seems that the version is 2.4. Since Apache runs on JRE, it seems to me that I should be able to have Apache 7 so long as I have Java 7, but the version numbers are throwing me off.

Why is the versioning so far off, and what do I need to do to be able to run apache 7 on my Mac? Developing on my Windows VM is an option, but I prefer to keep everything on the Mac side.

EDIT: It seems that I misunderstood: what I need is Apache Tomcat, which I now embarrassedly know is something different than Apache. If I have further issues I'll update accordingly.
