The Application Development & Research Of Embedded System Based Of J2ME

The field of embedded system faces to technology dense and application, which is companied by micro electronic, communication and electronic technologies,computer hardware,. The embedded system is a special system that focuses on the application and bases on computer technologies, clips in hardware and software ,have the strict demand of funcation, reliability, volume ,cost and so forth. It is popular in the domain of mobile computer equipments, communication, net equipments, information appliance, avation and spaceflight, auto electronic, intelligent appliance, industry control and so on, it has been a kind of new technologies that exists everywhere. It has been completely permeating and affecting every aspect of our life , so whichever in enterprise or consumed application, mobile software development technologies will have the great opportunities.J2ME is a simple platform that is special in the small equipment such as mobile phone ,net telephone, box of digital TV, navigation system, PDA, net switch and home auto equipment. Because J2ME has the character of Java, the java procedure complied by the J2ME can run in the every small device. The code has the flexibility, stability, transplant, net security .The paper is based on the current popular tool of J2ME, having the carrier of the example of the searching system of mobile train, and analyses embedded system based of J2ME completely and in detail and emphasis on the core technologies and design principle and design model, studies and researches deeply the advanced technologies, comprehend the development trait and procedure. Train the capability of analysis and deal with the assimilar system, master the flexibility, stability ,transplant, net security of the code edited by J2ME.If in future engaging in the direction of the computer, it will have an profound effect on the work.As the restrict of time and lab condition, there are many fault that will be completed in the future, welcome every reader and specialist to correct and criticize.
