Use this lesson to learn how to add nodes to the Web diagram of
your new project.
A Web diagram helps you visualize and change the flow of a Web application.
Before using the Web diagram editor, you should understand the following terms:
- A node represents a resource, such as a Web page, a Java™ bean, a Struts action, or a Web application.
- A connection represents the logic flow between two of these resources.
To create nodes on your Web diagram to represent two Web pages and a Struts action:
- Open the Web Parts drawer of the palette.
Drag a Web page node onto your diagram. The diagram shows a new Web page node
with the default name page.jsp.
Tip: When you create a new node in a Web diagram, the name of the node is automatically selected for editing. If you click elsewhere in the diagram before typing a new name, the new Web page name stays the same. To rename a node, click the name to highlight it, and then type a new name. - Type input.jsp as the new name of the Web
page node.
Note: As soon as you name the Web page node, the JavaServer Pages (JSP) file that this node represents is created in your DayOfWeek\WebContent Web project folder. - Type output.jsp as the name of the second
Web page.
- Drag a Struts action into the diagram to create a node called action1.
- Type computeDay as the name of the action
and press Enter. The Web diagram displays
an action node named /computeDay. The action is created in DayOfWeek\Struts\<default
module>\Actions.
Your Web project should include the following items: /computeDay, input.jsp,
and output.jsp.
