Simple answer:
You have to put a definition inside another definition. You can see a
definition as a "filled layout page". Since your main.jsp is not complete
by itself (you have to "put" pages inside its attributes), you cannot use
it as a simple tile (well you can but you get an error ;-)
I think this "problem" resides in the rewrite of the URL that Struts
makes.

an URL rewrite happens.

What I usually do is to put the data collected in the previous step into
hidden fields, so that they are re-posted in the next step. This way
I think the best thing is to make a custom tag library. The "formatting"

"getDataSource" is a protected method inside the class Action, so you

A common practice is to use the J2EE design pattern "Business Delegate",
that provides a clean separation between the technology used to store data
and all the rest of the application.
The Business Delegate will expose some "APIs", but it does not show how it
