Java was initially designed to control consumer electronics, such as pagers, which are typical embedded devices. Java designers attempt to build a simple, object-oriented, intelligent, interpreted, powerful, secure, reasonably structured, portable, high-performance, multi-thread, dy
of these two differences, Java introduces a concept called configuration, and then defines the embedded devices with limited computing functions and limited power in connected.The limited device configuration (cldc) specification, while the other device specification is the connected device configuration (CDC) specification. In other words, the concept of configuration is separated into two abstract types by all embedded devices. MIDPThe mobile information device profile (MIDP) is a Java API se
they often suddenly change from conception to reality. It took 41 years for wireless pagers to enter the market for the first time and 10 million of users, but now it takes only 10 months to popularize Web browsers, and less time for Napster. In the face of rapid technological and market changes, enterprises are forced to adapt to the market for organizational and institutional innovation.

After the establishment of the WAP server and the installation of the WAP browser, we can use the WML language to write WAP web pages or applications and debug them through the WAP Server and browser. Starting from this chapter, we will systematically learn the WML language. This chapter mainly describes the basic knowledge of the WML language, and the next chapter comprehensively describes the WML syntax, labels, and rules.

Mobile Information device profile (MIDP) defines an application programming interface (API) for running the MIDlet application in the MIDP container. This API is built on the Application Programming Interface of the limited connection device configuration (cldc. The Application Programming Interface Class of the MIDP user interface is not designed based on the Java Abstract Window Toolkit (AWT. They are designed for small mobile information device

I. cldcCldc 1.1 is the result of JCP specification JSR-30 and JSR-139 for resource-constrained consumer electronics.
Cldc features are as follows:1) the device must have at least-kb of memory.
2) the power supply of the equipment is limited. It is usually a battery-powered device.
3) Some networks can be connected, usually wireless networks, intermittent connections, and limited bandwidth (usually 9.6kbps or less ).
4) the complexity of the user interface var

Both ultraedit and notepad are commonly used editing software on the PC. We can use them to compile the code of the mobile phone program, and then use the wtk provided by Sun (j2_wireless Toolkit) compile, simulate, and upload the source code to the VM. The following describes how to install and use wtk.

I attended the portal Interest Group of the company and learned about the portal today. First, I checked some portal materials online and had a basic understanding of portal, Portlet, Portlet iner, jsr168, and other concepts. I decided to learn more about the portal, so I learned jetspeed.

WML is a markup language based on XML (Extensible Markup Language). This language is designed for users of wireless devices to provide an interactive interface. These wireless devices include telephones, pagers and personal digital assistants (Personal Digital assistants), and so on.
WML is designed for devices that have the following characteristics:
Small in size (relative to personal computer).
Limited memory and CPU size.
Communication belt width
