JavaServer Faces is a standard Java framework for building user interfaces for Web applications. It simplifies the development of the user interface, which is often one of the more difficult and tedious parts of Web application development. JavaServer Faces is designed to simplify the developers task while development of user interfaces for Java Web applications.

This article describes how to develop JavaServer Faces web applications with Eclipse. It demonstrates managed beans, validators, external resource bundles files and the JSF navigation concept.
JSF lifecycle contains 6 phases.As soon as a JSF Application in initiated by calling the Faces Servlet (which is configured in the web.xml file), series of activities will take place. These activities come under the category of JSF Request Processing Life-cycle Phases. The phases are
Java bean that can be accessed from JSF page is called Managed Bean. The managed bean can be a normal Java bean, which contains the getter and setter methods, business logic or even a backing bean.Managed beans works as Model for UI component.
In simple language Page Navigation means flow of the application from one page to another page.Navigation in JSF defines the set of rules for choosing the next view to be displayed after a specified action is completed. In JSF 1.x, navigation is generally
In this article I will show you how to create a simple JavaServer Faces (JSF) Web application starting from zero with Eclipse and Maven.It also demonstrates how Maven brings in the relevant dependent JAR files.
This example shows how to develop a simple User Login page by using JSF2, jdbc and MySQL. This application lets you validate user login credentials using jdbc and mysql database.
As you already aware, everything in JSF is governed by JSF life cycle. In our JSF Life Cycle tutorial we have discussed where and how JSF validation will happen.Validation is 3rd phase in life cycle. Any validation error at this stage
In this example we have a index page where user will ask to provide his card and payment details. On clicking Submit button, All field will be validated using JSF standard validator tag, if data validation is pass then user will be directed to result.jsp page
The login.jsp prompts the user to enter his/her details.We are validating the email id using our custom email validator.After successful validation user will be redirected to success.jsp page.In case of any data validation error message
In JSF user input is normally of String type which will be submitted to the server for further processing.However when request parameters are mapped to different backing bean properties internally, the String values need to be converted to different data types.
In JSF user input is normally of String type which will be submitted to the server for further processing.In this example we will discuss how to use jsf supplied Standard converters to convert the user input from String to different java data types.
In most of the scenario, JSF provided converters are sufficient. However, for application specific purposes, there may be a need to customize and convert the user entered string into some other data-type like phone no format. This can be done by using JSF Custom Converter.
JSF 2 comes with a very flexible conditional navigation rule to solve the complex page navigation flow.Conditional navigation enables you to set a pre-condition for navigation. This pre-condition needs to be met before allowing navigation to the specific view
here is some scenarios where you need information stored in one managed beans for the business logic in some other beans.There are two ways for one managed bean to access another managed bean information.We can use JSF 2 @ManagedProperty annotation for this purpose.
