Thanks!

Well, I examined sources of JspServlet and found it uses classloader to obtain
page stream, so it may be possible to provide a custom classloader, which will
obtain page sources from database or whatever - that will perfectly suit my
needs, the only thing I'm not sure is: it looks like container-wide setting,
i.e it can't be applied for only one web application - but for entire Tomcat
container? Also is it possible to arrange order of classloaders for tomcat
somehow?
