(we used c for the JSTL core namespace) to iterate through the ToDoList list object that was in our user s session When we placed the ToDoList list object in our portlet session in the application scope, it became available to our JSP pages The <c:forEach> tag exposes a LoopTagStatus object that we named status in our JSP which can be used to access the current count of the object If we had , built this portlet to use a database for storage, we would have used the primary key from the database here to ensure that the correct to-do list item would be used in the action request Instead, with our nonpersistent to-do list, we use the position of the item in the ArrayList to identify it To get this position, we use the getCount() method on the LoopTagStatus object.

We place it into a variable called itemId that we can reference as a value for a JSP tag attribute For each of the to-do items in the list, we display the description using the <c:out> tag from the core JSTL tag library The <c:out> tag can write the value of an expression to the output of the JSP page Our <c:forEach> tag places the current item (represented by a ToDoListBean) into the expression variable called item The <c:out> tag can use an expression from the JSTL expression language (EL) such as ${itemdescription} to render the value of the description field on the item object We used the <fmt:formatDate> tag from the formatting tag library to display the creation date in a readable format We specified the short date style, because we want to conserve room on the portal page.

int c = a + b; lblAns.Text = c.ToString(); }

The schema designer and Server Explorer together allow you to create a schema for a database table. Along the same lines, the XML Schema Definition tool allows you to create XSD schemas from the following: An existing XML document An existing XDR schema Types defined in an assembly (.exe or .dll)

Next, we checked the to-do list item s status to determine which message and portlet action link to display We used the <c:choose>, <c:when>, and <c:otherwise> tags to simulate an if..else statement The interesting part of the status display is the link we use to change the status of the to-do item The link is created with the <portlet:actionURL> JSP tag We added two parameters to the action URL tag: one for the action command, and one for the item to modify At the bottom of the page, we included a simple form to add a to-do item to the list It takes only the description as a parameter The HTML form s action is a portlet action URL that is also created with the <portlet:actionURL> tag We used the POST method for the form because it is required.

Now when you run the application, you ll see something like Figure 12-8. When you type the numbers into the text fields, nothing happens until you click the button, which triggers a postback and a full refresh of the page. Depending on your system speed, you may or may not see a page blink, but you can notice the full page refresh by looking at the status bar. You can convert this to an Ajax application without changing any code. To do this, drag and drop a ScriptManager control from the Toolbox onto the page. (Look back to Figure 12-6 to see the Toolbox.) After doing this, drop an UpdatePanel on the page, and then find the Panel control in the standard Toolbox and add a panel inside the UpdatePanel. The Panel resolves to a <div> at runtime, and can be resized within the Designer, causing the UpdatePanel to match it. See Figure 12-8 for an example.

Figure 5-2 shows the to-do list portlet running in VIEW mode..
