J2ME Learning Notes (IV.)

Notes these two days have been looking at some of the tools used in actual development, as well as some instance documents.
The first step must be to see J2ME Wireless Toolkit. WTK itself has a ktoolbar that claims to develop the environment, but I feel this

is actually just a packaged program, does not include the Java IDE, its role in the development of the program to pre-audit, create Jad

Pieces, and then package them as jar files. Of course, since the Jad file can be edited, then Ktoolbar itself can be regarded as a version control

System software. It is important to have a property version if a software is already installed on a handheld device so if the second installation

If the Version property is not installed, J2ME will judge the version attribute in Jad, and if so, consider that the software

is already installed and cannot be installed repeatedly. There is the Chinese problem in the Jad file, you must use the JDK's own native2ascii

The tool translates the Chinese to be displayed before it works correctly.
The last time in a J2ME QQ group inside a brother program can not install, the program error on the same jad file already exists, I can only

Said it was version of the problem. Oh, but another high man said is the Chinese problem ... I have no words, I can only say that I could almost.

But the program error is simply referring to the things I said. Forget it, maybe as a layman I'd better say less. Hey
Also looked at the MIDP for Palm OS, oh, relatively simple, and do not have anything to try at hand, so I looked at the approximate

。 Oh, Sun also provides a KVM and Java Application Manager's execution file, MIDP.PRC. and Converter.bat

It's about debugging the jar that passes through and the Jad file into a program RPC file that can be executed on the Palm OS.
Go to work, so also some tired, originally said that today MIDlet transaction processing to see, it is already almost 11 o'clock, oh, my life

Bitter, now ended Soho life, so to go to work, to wash and sleep slightly ... Transaction processing take a slow look. I believe an old saying, not afraid of slow

, just afraid of standing. I could only pray that I could take the time to see J2ME every day. At the same time I looked at JBuilder mobileset development tools.

。 However, I feel that I am not familiar with the transaction processing of the J2ME, so after learning the transaction processing, I will study it carefully jbuilder

Mobileset. Oh, as for eclipseme I think, take it slow. Oh..
