I'd hope they are experts, or at least have no trouble learning quickly. If they can't manage MSSQL or Tomcat, how do they set up their local development environment, implement automated integration tests, etc?
They inherit it from whoever worked on the code before them.
I work on Java every day. I probably have a better grasp of Tomcat than many people at my company. If we somehow magically lost all our Apache/Tomcat configuration files, there's no way in hell I could build it from scratch.
(I can, however, build a scalable system based around PHP web apps with my eyes closed. I'm not super proud of that.)
