Debugging the Mobile Application 
After deploying and running your application on the Mobile Client for Handhelds, you should test it and debug it locally. You may want to set breakpoints in the Java code to execute it step by step.
By default, the debug configuration Start Mobile Project is created when the application is run for the first time. This configuration starts the default installation of the Mobile Client for Handhelds. You can copy this configuration or customize it using Eclipse.
