How to carry out the visual development of JSF in NetBeans, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can get something.

NetBeans in the visual development of Java functions, with these functions as the basis, the visual development of JSF in NetBeans can be said to be natural. What accomplishes this mission is NetBeans's Visual Web Pack toolkit. Like other toolkits, this toolkit is free, but the free Visual Web Pack toolkit has surpassed most commercial development tools in many ways, especially in the development of JSF applications.

The Visual Web Pack toolkit provides powerful development tools for NetBeans. With the support of these tools, the development speed of Web applications has been greatly improved. Visualization is the core goal of the Visual Web Pack toolkit, so the Visual Web Pack toolkit contains several visual editors that can be used to quickly build standard Web applications using technologies such as AJAX, CCS and JSF.

When it comes to visual development, the first thing that comes to mind must be the development of Web pages. It is a painful process to develop Web pages with JSP technology. Early JSP mixed too many coding elements on the pages, which made the development and maintenance of JSP pages a programmer's nightmare. Although the current version of JSP has some improvements, there are still many shortcomings. JSF is an attempt by Sun to simplify Web development, which has been a great success with the support of the Visual Web Pack toolkit. Create a page, drag and drop components from the panel onto the page, edit the properties of the component, write event handling routines, and you don't see much "Web" from Visual Web Pack's steps to develop a Web page. Of course, Web applications are fundamentally different from desktop applications, but Visual Web Pack has encapsulated the difference between the two, and it feels like the development process of Web applications and ordinary desktop applications is exactly the same.

In addition to the UI components on the page, Visual Web Pack even extends the concept of visualization to other JSF components. For example, JSF's converters and validators are not originally visual components, but under Visual Web Pack, the process of binding converters and validators to a visual component is as simple as adding UI components to a page. This is thanks to the highly modular design of JSF. Any programming element is component and can be drag-and-drop.

It is not only this that can be drag-and-drop, complex database programming has also been visualized by Visual Web Pack. Once the database is configured, the easiest way to access the records in the database table from the page is only two steps: first, place a UI component on the page to display the data, such as the drop-down list component; and second, drag and drop a table directly onto the UI component. In this way, without any code, the drop-down list component displays all record values for the first non-key column in the table at run time. This is very useful in Web database applications. For example, with these two drag-and-drop operations, you can display a list of product categories on an e-commerce site for users to choose from. If this is too simple to meet your needs, you can also choose a more precise way to drag and drop the table onto the page (rather than on the component), and then bind to the data provider. Select the fields you want to display in the list. In this way, you can display not only the name of the commodity category, but also a brief description of the commodity category, and so on.

Page navigation is a unique requirement of Web applications. Unlike other frameworks, JSF's page navigation is centralized, which is an initiative of JSF. Web application is composed of pages. When the size of the application increases and the number of pages increases to a certain extent, navigation in the page is a bit like sailing in the sea, and it is easy for people to lose their direction. Decentralized navigation control is simple and easy in small-scale applications, but large-scale applications are more suitable for JSF centralized navigation control. Visual Web Pack provides a visual page navigation designer, open the designer, Visual Web Pack will automatically display all the pages of the application as a small icon, and the so-called navigation, just drag a line from one page to another, that's all, vivid and intuitive. A connection is called an exit, and after naming the exit, you can navigate to the specified page by selecting the exit in the code.
