Sun Java System Calendar Server
open-in-new
<p>The Sun Java System Calendar Server was <a href="/facts/Sun_Microsystems%2c_Inc./VJ9EzEFd">Sun</a>'s calendar (<a href="/facts/Calendaring_software/ICfDpsUR">scheduling</a>) server. The currently available version is 6.3 which is now part of the <a href="/facts/Sun_Java_System_Communications_Suite/cXL6ctu5">Sun Java System Communications Suite</a>. </p><p>Users can access their calendar and task list items using a variety of clients. Web browsers will be able to access Calendar data using <a href="/facts/Sun_Java_System_Communications_Express/Dxd8aTyB">Sun Java System Communications Express</a> as an HTML-based client. <a href="/facts/Microsoft_Outlook/cMGCKGFJ">Microsoft Outlook</a> users can access their calendar data using the Sun Java System Connector for Microsoft Outlook, which is not yet compatible with Outlook 2010. <a href="/facts/Mozilla_Thunderbird/20lnTsYS">Mozilla Thunderbird</a> users can add fully functional calendar access to the Sun Calendar Server to the email software by adding the <a href="/facts/Mozilla_Lightning/fS0c6Rbp">Mozilla Lightning</a> extension for WCAP (<a href="/facts/Web_Calendar_Access_Protocol/edgYkfnP">Web Calendar Access Protocol</a>). Finally, starting in 2008, the <a href="/facts/Sun_Java_System_Communications_Suite/cXL6ctu5">Sun Java System Communications Suite</a> 6 will include an AJAX-based Web client which will provide better "thick client-like" user interactions. </p><p>A useful feature of Calendar Server is the notification service. This service will send an e-mail or an SMS to the calendar owner. These messages are sent to the calendar owner if he/she has been invited to an appointment or as a reminder of an upcoming appointment. These reminders are directed to a person's cell phone by using their phone carrier's email address assigned to their phone. </p><p>The notification services are also useful for developers to implement their own software applications. Calendar reminders and change events are published to a <a href="/facts/Java_Message_Service/aTzyVj3n">Java Message Service</a> using Sun Java System Message Queue. </p><p>Developers may use the WCAP interface to write their own applications which access calendars, tasks, and look up "free busy" information on users. This interface returns calendar data in a number of formats including <a href="/facts/XML/clNgUfWk">XML</a> and <a href="/facts/ICalendar/0hbY7Pt2">iCalendar</a>. <a href="/facts/JSON/bs1rUAhd">JSON</a> (JavaScript Object Notation) format was added to support AJAX development in the latest patch of Calendar Server 6.3. </p>
