J2ME HELLOWORLD Small Test

T628 Price, bought a play, this "chicken" support Java expansion, so the first time to Http://developer.sonyericsson.com/site/global/home/p_ home.jsp Download the latest SDK (FILE size:42m), please note that the SDK description should indicate that support t628,eclipse and eclipseme are already good, the following should be installed:

1, install J2SE 1.4.2, and configure path and Classpath
2, install Semc_j2me_sdk_2_1_5.exe, after loading I did not do any configuration (including environment variable configuration)
3, extract eclipse, and then extract eclipseme into Eclipse's plugins directory
4, then configure Eclipseme (Figure 1)
5, create a jeme project, File/new/project.../j2me/j2me Midlet Suite
6, add Midlet,file/new/other in the project. /j2me/j2me Midlet
7, write code
8, in the Navigator of the project on the right button, the implementation of the right menu J2me/create Package
9, with the simulator (Figure 2) or via Bluetooth to the phone to perform

(Figure 1)

(Figure 2)

Tip: T628 only supports CLDC 1.0 and MIDP 1.0, in the new construction project, the platform chooses the Sony Ericsson J2ME SDK (WTK 1.0.4) Platform, if you choose the Sony Ericsson J2ME SDK (WTK 2.1) Platform, you can run on the emulator, but uploading to the T628 will prompt an invalid application.
