1. A method for exchanging portlet configuration data of a portal, comprising: providing a graphical user interface (GUI) component as part of a portlet view provided by a portal page for triggering a portlet configuration exchange process between a first user using a first portlet instance and a second user using a second portlet instance within the same portal, the first and second portlet instances being of the same portlet type, providing an export functionality allowing access to stored portlet configuration data of the first portal instance and transforming the stored portlet configuration data into a data structure for exchange purposes, allowing for exchange of the data structure via a defined communication channel between the first user and the second user, and providing an import functionality allowing for parsing of the data structure to provide new portlet configuration data of the second portlet instance and storing the new portlet configuration data of the second portlet instance.
