Debugging applications

MTJ uses Eclipse's built-in debug function in debugging the Java ME applications. In order to successfully debug your applications, you need to edit some of the Eclipse's debug settings.
To edit the debug settings

In the menu bar, select Window -> Preferences.
The Preferences window opens.
In the left-side pane, select Java -> Debug.
The Debug pane opens on the right side.
In the Suspend Execution field, uncheck all the suspend options.
In the Communication field:

In the Debugger timeout (ms) field, set the value to 20000 or greater.
In the Launch timeout (ms) field, confirm that the value is set to 20000 or greater

Note: The values can be greater than 20000, depending on the speed of your computer. If the values are too small, MTJ might freeze when you try to debug your applications.

Click OK.
