How to export data of a custom portlet into a LAR file programatically ?

Are you asking how to add export/import to your portlet?
The first step is to add Configuration to your portlet so when a user select Options, Export/Import will show up in the menu.
The next step is to implement export/import. Check the following wiki for more information.

hi hitoshi,

Can you please tell me how to link export/import tab as shown in the following (export-import.png) with (export.import.png)..i mean how to get "export" button and "cancel" button in (export.import.png)

Just specify PorletDataHandlerImpl you've created in <portlet-data-handler-class> tag in the liferay-portlet.xml file.

Example:
<portlet-data-handler-class>com.liferay.portlet.calendar.lar.CalendarPortletDataHandlerImpl</portlet-data-handler-class>

Have you looked at the source for Calendar's export/import

portal-impl\src\com\liferay\portlet\calendar\lar

hi hitoshi,

Thanks a lot dude..everything is working fine now..

Great! Liferay's source code offers one of the best examples around to develop liferay portlets. I goes through them often myself when I get stuck from just reading the documentation.
