Hi,
In order to get the first drop down, u can use the existing liferay method
OrganizationLocalServiceUtil.search

Then after some one select any organization from first drop down, post again and get the users for that organization using

UserLocalServiceUtil.search method

Thanks
Zankar

Thanks for reply.


Is there any mechanism without submitting the form can we get the second list to be populated by using ajax or can we able to call Java method from javascript.

Thanks
Venkat

Ya sure we can use doing ajax in liferay. Liferay provides AjaxUtil for doing all kind of partial submit and other feature. check the following example code

var message = Liferay.Popup(
{
width: 350,
height: 300,
modal: true,
title: "Share"
});

url = "ur post url";

AjaxUtil.update(url, message, {onComplete: function() {Liferay.Popup.center()}});
