Chapter 2 Developing MIDlet Suites 9

FIGURE 5 Messages about building

Behind the scenes, the J2ME Wireless Toolkit also preverifies the compiled class

files. MIDlet class files must be preverified before they can be run on a MIDP

device or emulator. The toolkit quietly handles this detail for you; you probably

won’t ever realize it’s happening. See the CLDC specification for more information

on preverification.

2.2.3 Run

Once the project builds successfully, you are ready to try it out in the emulator.

Click on the Run button. The emulator pops up and shows a list of all the MIDlets

in your project.
