Answer 1

Tomcat has an auto deploy feature. When you update JSP files it detects you have done so, compiles it, and replaces the old compiled JSP page with the new one that it compiles into a java class.

If you don't want that to happen, you can turn off the auto deploy feature for your web application. It is described in the link how you do that.
