It is not necessary to learn every feature of the NetBeans IDE before exploring its GUI creation capabilities. In fact, the only features that you really need to understand are the Palette, the Design Area, the Property Editor, and the Inspector. We will discuss these features below. The PaletteThe Palette contains all of the components offered by the Swing API.

You can probably already guess what many of these components are for, even if this is your first time using them ( JLabel is a text label, JList is a drop-down list, etc.)This figure has been reduced to fit on the page.Click the image to view it at its natural size.From this list, our application will use only JLabel (a basic text label), JTextField (for the user to enter the temperature), and JButton (to convert the temperature from Celsius to Fahrenheit.)The Design AreaThe Design Area is where you will visually construct your GUI. It has two views: source view, and design view. Design view is the default, as shown below. You can toggle between views at any time by clicking their respective tabs.This figure has been reduced to fit on the page.Click the image to view it at its natural size.The figure above shows a single JFrame object, as represented by the large shaded rectangle with blue border. Commonly expected behavior (such as quitting when the user clicks the 'close' button) is auto-generated by the IDE and appears in the source view between uneditable blue sections of code known as guarded blocks.This figure has been reduced to fit on the page.Click the image to view it at its natural size.A quick look at the source view reveals that the IDE has created a private method named initComponents, which initializes the various components of the GUI.

It also tells the application to 'exit on close', performs some layout-specific tasks, then packs the (soon to be added) components together on screen.Don't feel that you need to understand this code in any detail; we mention it here simply to explore the source tab. For more information about these components, see:and.

The Property EditorThe Property Editor does what its name implies: it allows you to edit the properties of each component. The Property Editor is intuitive to use; in it you will see a series of rows — one row per property — that you can click and edit without entering the source code directly. The following figure shows the Property Editor for the newly added JFrame object:This figure has been reduced to fit on the page.Click the image to view it at its natural size.The screenshot above shows the various properties of this object, such as background color, foreground color, font, and cursor. The InspectorThe last component of the NetBeans IDE that we will use in this lesson is the Inspector:The InspectorThe Inspector provides a graphical representation of your application's components.

We will use the Inspector only once, to change a few variable names to something other than their defaults.

Building and Running a Web Application ProjectThe original tutorial can be found at. All credits must go to the original authors. In this tutorial we try to refine all the steps to more details using screen shots.Machine specification used in this task are:.Intel Pentium Core 2 Duo, 2.2 GHz,.Windows XP Pro SP2 + periodical patches + periodical updates.2 GB DDR2 RAM.160 GB SATA HDD.17” SyncMaster 713N monitor.Pre requirement1.2. To work through this tutorial, you must have a server registered in the IDE. The Web and Java EE installation enables you to optionally install and register the Apache Tomcat servlet container 6.0.14, and the GlassFish V2 application server.3. If you are installing NetBeans IDE for the first time, you need to have the (JDK) installed. The JDK includes the Java Runtime Environment (JRE), as well as various tools and API's necessary for development in Java.Setting Up a Web Application Project1.

Choose File New Project (Ctrl-Shift-N) from the main menu. Under Categories, select Web. Under Projects, select Web Application then click Next.2. In Step 2, enter HelloWeb in the Project Name text box. Notice that the Context Path (i.e., on the server) becomes /HelloWeb.3. Specify the Project Location to any directory on your computer.

For purposes of this tutorial, this directory is referred to as $PROJECTHOME.4. Select the server to which you want to deploy your application. Only servers that are registered with the IDE are listed. In this case we select GlassFish V2. Click Next.5.

Leave the Set as Main Project option selected and click Finish. The IDE creates the $PROJECTHOME/HelloWeb project folder. The project folder contains all of your sources and project metadata, such as the project's Ant build script. The HelloWeb project opens in the IDE. The welcome page, index.jsp, opens in the Source Editor in the main window. You can view the project's file structure in the Files window (Ctrl-2), and its logical structure in the Projects window (Ctrl-1):Creating and Editing Web Application Source FilesCreating and editing source files is the most important function that the IDE serves. After all, that is probably what you spend most of your day doing.

The IDE provides a wide range of tools that can compliment any developer's personal style, whether you prefer to code everything by hand or want the IDE to generate large chunks of code for you.Creating a Java Package and a Java Source File1. In the Projects window, expand the Source Packages node. Note the Source Packages node only contains an empty default package node.2. Right-click the Source Packages node and choose New Java Class. Enter NameHandler in the Class Name text box and type org.mypackage.hello in the Package combo box. Click Finish.

Rpc program not registered solaris. Notice that the new NameHandler.java file opens in the Source Editor.
