Cincom VisualWorks Web Toolkit Tutorial : ASP Model Summary

ASP Model Summary

This section of the Web Toolkit tutorial was designed to teach you how to develop Smalltalk Server Pages (SSP) using the Active Server Page (ASP) model. It assumed you knew little to nothing about web programming (HTML) but a little something about Smalltalk. We hoped that you liked the approach that this tutorial took in trying to get you coding as quickly as possible. By now, you should have a good foundation of the SSP "basics" and are ready to move to the next section of this tutorial which deals with the more advanced concepts found in the Java 2 Enterprise Edition (J2EE) model.

If you worked through all the exercises and took advantage of all the additional primers, you have covered quite a lot. This section of the tutorial was not meant to exposed everything these is to know about the ASP model but enough that should you pick up a book about ASP, you would have an easier time getting through that material.

Just in case you had trouble getting all the code working in this section, click here to view a ZIP file that contains the entire ASP and J2EE model solutions.

Just as a refresher, below is a list of major concepts that have been covered in this section of the tutorial. As you can see, you've made a very impressive start and have accomplished a great deal.

You now should know how to:

	Identify various ways of outputting to the HTML data stream
	Use the response write: method
	Use Smalltalk code all within an “SSP” to display a list of employees from a data file
	Use a combination of Smalltalk code and custom objects to display a list of employees from a data file
	Identify how to pass data from one SSP page to another.
	Forms send data via named pairs to the next SSP page
	Create and use cookies
	Query Strings send data via named pairs in the URL of a page
	Create and use session variables
	Use the redirect: method of the response object
	Identify the limitation of a redirect statement
	Create an include file
	Modify an SSP page that pulls in an include file
	Verify that a change to an include file changes all files that pull it in
	Test for the presence/absence of session variables
	Use session variables like objects
	Make use of a session variable to hold an object instance and reuse it
	Make changes to web pages by making changes to custom objects in the Smalltalk image
