Creating a simple MIDlet

In this section, you will create a new MIDlet class, which is a Java class that derives from the javax.microedition.midlet.MIDlet superclass.

Java ME perspective

  1. In the Package Explorer view, right click the src folder and select the Open the Java ME MIDlet wizard New > Java ME MIDlet wizard.

    Select the Java ME MIDlet wizard

  2. On the New Java ME MIDlet wizard, select the appropriate information for the MIDlet to be generated. With the exception of the Add to Application Descriptor checkbox, all other information are the similar to the standard class creation parameters from JDT.

    Note that only classes derived from the javax.microedition.midlet.MIDlet class can be used in the Superclass field.

  3. Select the checkbox for Add to Application Descriptor.

    When this parameter is selected, the newly created MIDlet will automatically be added to the project's Application Descriptor with default information. The MIDlet information may be further refined by accessing the Application Descriptor Editor.

    Note that if you do not select the Add to Application Descriptor option, you must use the Application Descriptor Editor to enter the details for the particular MIDlet so it is properly registered as part of the project's MIDlet suite. If you do not do this, Java ME devices will not be able to access the MIDlet.

  4. Click Finish to create the new MIDlet class.
  5. The new MIDlet class is opened in the editor.
