Creating your first MIDlet
To create a MIDlet, you first need to create a MTJ MIDlet Project. You
can then either write the code in MTJ or import the code from file system
or CVS. As a pre-requisite, you need to have the following stored on your
computer and configured for MTJ before the MIDlet creation:
- Mobile SDK for the Device Platform
You can also change the mobile SDK later.
- The deployment tool
- The key tool and the signing tool
- A certificate from a trusted CA
The following steps display the work
flow for creating a MIDlet.
- Create the Java
Class for your MIDlet.
You can use the Create New Class wizard.
- Create a
MIDlet project.
Make sure the desired mobile SDK is stored on your computer before
starting the New Project wizard.
- Provide the code for the MIDlet.
- Build the project.
This process creates the deployed folder, which contains the JAR and
JAD file.
- Edit the JAD file
using the Application Descriptor Editor.
- Debug the MIDlet.
You can use Eclipse's built in Debug process, which can be accessed
from the file menu, by selecting Run
-> Debug.
- Run the MIDlet
to test it.
In the file menu, select Run ->
Run to test the application in an emulator.
- Sign the application.
This includes also the definition of the MIDlet's permissions.
- Deploy
the application to a mobile device or file storage.
