How to read contacts using JSR 75

Comments

ReadPIM.java is causing some intialization exception... so anybody can sort it out... plzz

Some how this code is not fetching contacts from N96. What could be wrong in it. It is just fetching numbers. Please reply if any one of you know about this issue.

This article mekes us understand very well about PIM api.

Easy to understand.

Here this article creates a midlet that displays a name and contact numbers in a form.It has a class that is PIMMidlet that has two instances of ReadPIM and Display. First the Display class sets the current display as a form that derives a class that is ReadPIM.

readContacts() method creates a contact list and append it into the form.

This MIDlet reads the contact names and numbers from the Phonebook using JSR 75

import javax.microedition.midlet.*;

	{
		display = Display.getDisplay(this);
		readPim  = new ReadPIM(this);
		display.setCurrent(readPim);
	}
	public void pauseApp()
	{
	}
	public void destroyApp(boolean uc)
	{
	}
}
