database table structure. You can of course create the schema manually as described previously, but there is a yet another way. Visual Studio has a built-in tool called Server Explorer that allows you to connect with the databases and manipulate database objects such as tables and stored procedures. Figure 5-9 shows the Server Explorer with the famous Northwind database opened.

5

<script type="text/javascript"> <!-Sys.Application.initialize(); // --> </script> </form> </body> </html>

prd.include(request, response); }

Note You can open Server Explorer by choosing View Server Explorer from the Visual Studio menu. The Server Explorer window has a Data Connections node that lists previously added database connections. To add a new connection, you need to right-click the Data Connections node and choose the Add Connection option. The Add Connection dialog box opens, allowing you to specify connection string parameters.

This portlet concerns itself with data operations and page display dispatching. In the next section, we discuss the JSP pages that display the content of the application. We also briefly introduce the Java Standard Tag Library (JSTL), which we use in the JSP pages but that does not have anything to do with portals or portlets.

There s lots of new stuff here. You ll be seeing how this all hangs together as you work through this book, but for now consider the <script> blocks referencing WebResource.axd and ScriptResource.axd. These guys are downloading the various script libraries that the browser needs for this page. Part of this is to support the core extensions to JavaScript, adding object orientation so that calls like Sys.Application.Initialize() make sense.

Using the Java Standard Tag Library (JSTL)

Figure 5-9. Server Explorer of Visual Studio As you can see in Figure 5-9, Server Explorer has displayed a list of all the tables, such as Employees and Customers. Now suppose that you want to represent data from the Employees table as an XML file. It would be helpful in such a case if you could create an XSD schema that maps closely to the underlying table structure. This way, synchronizing the XML file with the database at a later stage will be easy. To see how an XSD schema can be created from a database table, add a new XML schema to your project. Then open Server Explorer and locate the desired table. If Server Explorer is not opened by default, you can open it by choosing View Server Explorer from the menu. Finally, drag and drop the table from Server Explorer onto the XML schema. That s it! The Visual Studio IDE is clever enough to create an equivalent XML schema. Figure 5-10 shows an XML schema generated by dragging and dropping the Employees table of the Northwind database onto the schema designer.

One of the nicest things about ASP .NET AJAX is the fact that the UpdatePanel control can be used to add AJAX functionality to an existing ASP.NET application. This is simply achieved by wrapping the relevant controls with an UpdatePanel. Consider the following example. Add a new web form to your application and call it AddWithUpdatePanel.aspx. On this form, add a couple of text boxes, a button, and a label, and call them txtA, txtB, btnAdd, and lblAns, respectively. The source of your page should look like this:

We use the Java Standard Tag Library (JSTL) in our JSP pages for convenience. The JSTL tag library works the same way in a portlet application as it does in a web application. The to-do portlet will use the Standard Taglib 1.0.4 from the Jakarta Apache Taglibs project (http://jakarta.apache.org/taglibs/doc/ standard-1.0-doc/intro.html).
