2. I'm trying to build bit complex website based on JSP (which I've
done a lot in PHP, so the main idea of website engineering is quite
common for me), but I a bit confused about the architecture/structure
of a JSP webpage building. The problem is, I'm not able to imagine in
my mind, how the architecture (directory structure) should be found,
how do I divide the template files, the engine core, etc.

3. What I've done in PHP, is quite simple structural solution, which
looked like following:

mainFile {
   switch( __mainArgument from _GET ) {
     case "myPlugin":
        include "myPlugin.inc.php";
     break;
     /// And so on, and so on
   }
}

The problem is, that the switch() java statement is not supporting
Strings - okay - so I'm not able to such as above.


You could use if statements.

But you really should use a servlet instead of a JSP page
to do that.

Which could either be your own servlet or one of the many
MVC web frameworks.

matter at all, because I thought that I'll just divide my website into
subfolders, such as:

Web Pages \
    \index.jsp
    \news\index.jsp
    \users\index.jsp
    \requests\index.jsp

That sollution is quite okay for me - any other suggestions?


I do not see the correlation with the previous section,
but it seems OK.

 > - but I

was wondering what about dynamic elements, which are visible in any
index.jsp (and \*\index.jsp) file? Let me show it on an example:

/// index.jsp
<html>
<body>
   <div>
     [DEPEND ON \%s\index.jsp CONTENT HERE] [1]
   </div>
   <div>
     [DEFAULT CONTENT of \%s\index.jsp] [2]
   </div>
</body>
</html>

The [2] position is quite simple, because it might be defined directly
in my file, but what if I include in [1] position a file, which is
also included in base index.jsp (ROOT)? There should be a submenu
display, which should display menu items regarding to the module
selected.


If you want to do that then I think you should look at something
like Tiles.

Shall I use the mod_rewrite (ie. /any_here/index.jsp> /index.jsp?
module=any_here - then the request parameter fetching is much easier.


I do not see any need for mod_rewrite.
