Re: New Turbine User needs (a lot of) help

[Steve Ruby <st...@rubysolutions.com>]

Your screen code should extend one of the available
screen classes in Turbine (like VelocityScreen) and implement
doBuildTemplate(Rundata,Context)

The screen is not a servlet..
the URL to the screen is
http://myserver/myapplication/servlet/Turbine/template/Login
(unless you made changes to web.xml)

Turbine itself is the only servlet in a turbine setup all other
java clases are screens, actions and other stuff that you write to make
your screens and actions work.

Think about a vm/wm Document with the same name in templates/screens

Depending on the Configuration, the Login will be called automatically, or
you can "manually" call it by setting the Screen in either the Javafile or
the
(calling) document.

Example (untested):

in the Document:

    $data.getTemplateInfo().setScreen("Login")

I believe, there is a reference in the TemplateLink Object also...

    $link.setScreen("whatever")

will cause the above named screen to be executed...
ask me, if you need more info :) I'm just a beginner,
but I had the same difficulties understanding the principles

btw: the FSD might be a good source for you...
