absolute newbie - where to look for source code

[Cal Abao]

I am looking into the viability of auto-refreshing
a page in a web application consisting of java code, among others.
I intend to use <meta http-equiv="refresh" content="7;....
I do not want to autorefresh every page but only certain pages.
Where do I look to find out which code produces which page so that I can insert the meta command to autorefresh ?
Clicking on the source of the browser does not
seem to indicate which code actually displays/
generates the page.
(The code is not written in-house but I have access to the source codes *.java, *.xml etc)

One piece of java code can generate lots of different html pages. So no you can't look at the html to figure out which java program created it. And you don't need to. Because you have the source code. Which is all you need. The source code tells you how each html page is create.

It is really hard to say. It is soooo variable with each web app.
