Java server faces development tools

Every view has it's own view id and it is stored in the FacesContext's session object. JSF View is collection of components associated with its current state. After the component tree is restored, each component in the tree extracts its new value from the request parameters by using its decode method.

The value is then stored locally on the component. If the conversion of the value fails, an error message associated with the component is generated and queued on FacesContext. This message will be displayed during the render response phase, along with any validation errors resulting from the process validations phase.

During this phase, the JavaServer Faces implementation processes all validators registered on the components in the tree.

It examines the component attributes that specify the rules for the validation and compares these rules to the local value stored for the component. After the JSF checks that the data is valid, it walks over the component tree and set the corresponding server-side object properties to the components' local values.

The JSF will update the bean properties corresponding to input component's value attribute. During this phase, the JavaServer Faces implementation handles any application-level events, such as submitting a form or linking to another page.

At this point, if the application needs to redirect to a different web application resource or generate a response that does not contain any JavaServer Faces components, it can call FacesContext. If the view being processed was reconstructed from state information from a previous request and if a component has fired an event, these events are broadcast to interested listeners.

If this is an initial request, the components represented on the page will be added to the component tree as the JSP container executes the page.

If this is not an initial request, the components are already added to the tree so they needn't be added again. In either case, the components will render themselves as the JSP container traverses the tags in the page. About Us Contact Privacy Policy. Java Web Tutor Developer Zone. The appropriate Faces components are added to the page for use with the defined data sources. These Faces components are bound to the defined data source.

For instance, a data table may be added to a Web page if a relational record list is used. A table of components may be added to a Web page if a relational record is used. Each field in the relational record is represented as a row in the table. The components that are contained within each row depend on the types of data being added and how the user intends to use the relational record within the Web page that is, for creating, updating, or displaying.

Continue to design your page by dragging other Faces components from the palette to the page. You can drop components such as input fields, command buttons, hyperlinks, tabbed panels, and media players. Note: The following browsers are supported for displaying Faces components: Microsoft Internet Explorer 5.

Edit the properties for each component. When you have focus on a component in the Design or Source page of Page Designer, the Properties view displays the properties available for that component.

If you add a Faces component directly from the palette, you can bind the component to a defined data source in the Properties view for the component. Use the Quick Edit view to add scripted events to your Web pages. Test your JSP files periodically as you develop your pages using Faces components. Because Faces components use dynamic data, you should run on server to preview. The preview page located on the tab at the bottom of the Faces JSP file will not be as accurate.

Run the Web project on the server. Refer to the server documentation to learn more about testing and deploying your Web application. At run time, HTML and form tags are produced. After the Web application is deployed, the user can access and manipulate data directly from the Web application.

Note: Please see translation of this page in Danish by Sandra Knudsen. Web Development Next. An extensive set of reusable user interface UI components. There are two relational record components you can work with: A single relational record: This component returns a single relational record and the properties of the record are generally bound to input or output components.
