However, once you master a framework, you could develop better applications in faster time.
Java Server-Side Programming
However, there are many frameworks available. Choosing one could be an issue. Ruby has Ruby on Rails.
Before writing our first JSF program, I shall assume that you have installed and configured Tomcat server. Otherwise, read " How to install Tomcat ".
Let's define a new web context web application called " hellojsf " in Tomcat for our JSF Hello-world application. First of all, we need to create the standard directory structure for the web context as shown in the figure below.
Create sub-sub-directories: Write the following web configuration file " web. Write the following JSP file, and save it as " hello.
Start the Tomcat server. Check for the following messages to confirm that web context " hellojsf " has been started. Also take note of the JSF Mojarra version number. You shall see the output text "Hello, world! JSF is primarily meant for creating UI such as texts, input box, etc.
Write the following JSF codes, and save it as " hello. Take note that the file extension for facelet is ". Use "View Source" to check the output generated. Let us write the UI for user input called " input. To define the navigation rule and manage the Javabean, a configuration file called " faces-config. Input "someone" into the text box, and click OK. The output shows "Hello, someone! We also included an image. There is no need to do any configuration for this example under JSF 2.
You may need to provide an empty skeleton save as " faces-config. JSF provides two custom taglibs: The html custom tags are used to generate HTML codes. A JSF user interface is called a view.
Other optional attributes can be applied, e. Latest version tested: JDK 1.
JavaServer Faces (JSF) (1.2, 2.0 and 2.1)
October, JSF supports: Standard user interface components like input fields, buttons, and links. Navigation between pages. User input validation, error handling and event handing. Javabean management. Internationalization support. Java EE 5 Java Servlet 2.
Bundled in GlassFish 3. Example 1 a: Hello-world Let us begin with a Hello-world example. Step 1: Keep the files in the appropriate directories: This directory is known as context root , and keeps the " jsp ", " html " and resources available to web users.
Keeps the webapp configuration files, such as " web. Keeps the java program source files optional. Keeps the java classes. NetBeans Create a new webapp project: A welcome file " index. Issue URL http: The " jsf-api. The " jstl. Skip the following steps 2, 3, and 4, which has been done by NetBeans. Step 2: Copy "jstl. Two JSF taglibs are used: core with prefix f and html with prefix h. Step 6: Start Tomcat Start the Tomcat server.
Check for the following messages to confirm that web context "hellojsf" has been started.
Also take note of the JSF Mojarra version number. JSF is primarily meant for creating UI such as texts, input box, etc. Write the following JSF codes, and save it as "hello.
Take note that the file extension for facelet is ". Line 4 declares the namespace for JSF html taglib with prefix h.
Use "View Source" to check the output generated. The user's input will be saved in a Javabean's field called name. The Javabean is referred to as userBean. JavaBean "mypkg. For instance, it has a no-arg constructor; if the class has a private instance variable called xxx, there shall be a public getter called getXxx and a public setter called setXxx.
The rationale of having this rule is if we find public methods getXxx and setXxx , we can infer that there is a private variable called xxx, even thought private entities are not exposed to the user. The above Javabean simply define a private instance variable called name, and its public getter and setter.
JSP pages references the private variable name via the public getter and setter.
The purpose of this bean is to capture and save the user's input after the user clicks the submit button, and return this value to the response page. This bean provides a bridge between the JSP pages and the application logic i. Configuring "faces-config.
A managed bean called userBean this name is used by the JSP pages is defined. It is implemented in class MyUserBean in package mypkg. The bean has session scope, and is available to all the requests under the current client session. Input "someone" into the text box, and click OK. The output shows "Hello, someone! We also included an image. The value attribute specifies the storage location of the user input.
We shall configure this JavaBean later. The action attribute specifies the processing page of this form, i.Start by making changes to index.
However, once you master a framework, you could develop better applications in faster time. Test whether the above EL expression does in fact call the setUserNumber method when the request is processed. The html custom tags are used to generate HTML codes. You can do this by clicking in the left margin. It also provides development support when EL errors occur by enabling you to inspect the stack trace, component tree, and scoped variables.
