How is jsf compiled

Facelets is a part of the JavaServer Faces specification and also the preferred presentation technology for building JavaServer Faces technology-based applications. Facelets is a powerful but lightweight page declaration language that is used to build JavaServer Faces views using HTML style templates and to build component trees. Facelets features include the following:.

In short, the use of Facelets reduces the time and effort that needs to be spent on development and deployment. JavaServer Faces technology supports various tag libraries to add components to a web page. Table 5—1 lists the tag libraries supported by Facelets. In addition, Facelets supports tags for composite components for which you can declare custom prefixes.

For more information on composite components, see Composite Components. EL expressions can be used to bind component objects or values to methods or properties of managed beans. This section describes the general steps involved in developing a JavaServer Faces application. The following tasks are usually required:. The example used in this tutorial is the guessnumber application. The application presents you with a page that asks you to guess a number between 0 and 10, validates your input against a random number, and responds with another page that informs you whether you guessed the number correctly or incorrectly.

In a typical JavaServer Faces application, each page of the application connects to a backing bean, a type of managed bean. The backing bean defines the methods and properties that are associated with the components. The following managed bean class, UserNumberBean. Note the use of the ManagedBean annotation, which registers the backing bean as a resource with JavaServer Faces implementation.

The SessionScoped annotation registers the bean scope as session. Creating a page or view is the responsibility of a page author. This task involves adding components on the pages, wiring the components to backing bean values and properties, and registering converters, validators, or listeners onto the components. The first page of the example application is a page called greeting. A closer look at various sections of this web page provides more information.

The input value is validated for value range by the JavaServer Faces standard validator f:validateLongRange. The image file, wave. For more details about the resources facility, see Resources. A commandButton component with the ID submit starts validation of the input data when a user clicks the button. Using implicit navigation, the component redirects the client to another page, response.

Configuring a JavaServer Faces application involves mapping the Faces Servlet in the web deployment descriptor file, such as a web. In such an IDE-created web. Here is an example web. This parameter identifies the status of a JavaServer Faces application in the software lifecycle. The stage of an application can affect the behavior of the application.

For example, if the project stage is defined as Development , debugging information is automatically generated for the user. If not defined by the user, the default project stage is Production. This command calls the default target, which builds and packages the application into a WAR file, guessnumber.

JavaServer Faces technology provides the tools to implement user interfaces that are easy to extend and reuse. Templating is a useful Facelets feature that allows you to create a page that will act as the base, or template , for the other pages in an application. By using templates, you can reuse code and avoid recreating similarly constructed pages. Templating also helps in maintaining a standard look and feel in an application with a large number of pages.

So, to solve your problem, you have to rename your EL function name to for example isInstanceOf or something. There is a mismatch in the format for the month and its value in the string. The format is MM which specifies two digits but the value is 9 which is a single digit. You can use single letters for month, day, year, hour, minute, seconds etc.

Also, I suggest you parse it in a case-insensitive way so that upper and lower case e. AM and am both can be accommodated. There is a way. Why not JSF pages are precompiled atleast partially but instead parsed, evaluated each time view is built? Asked 4 Months ago Answers: 5 Viewed 29 times. The EL 2. Instant; import java. LocalDateTime; import java. ZoneOffset; import java. JavaServer Faces technology supports various tag libraries to add components to a web page.

Table lists the tag libraries supported by Facelets. Tags for JavaServer Faces custom actions that are independent of any particular render kit. Facelets provides two namespaces to support HTML5-friendly markup. Facelets supports tags for composite components, for which you can declare custom prefixes. For more information on composite components, see Composite Components. The namespace prefixes shown in the table are conventional, not mandatory.
