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, receiving a request for exchange of the portlet configuration data of the first portlet instance in response to an actuation of the GUI component by the first user, providing an export functionality allowing access to stored portlet configuration data of the first portal instance, extracting the stored portlet configuration data of the first portlet instance, and transforming the stored portlet configuration data into a generated data structure for exchange purposes of the portlet configuration data of the first portlet instance to the second user, allowing for exchange of the data structure via a defined communication channel between the first user and the second user, wherein a GUI dialog is displayed to the first user for specifying the defined communication for exchanging the portlet configuration data and the data structure is exported via the defined communication channel to a storage location, receiving a request to import the portlet configuration data of the first portlet instance by actuating the GUI component by the second user, providing an import functionality by displaying a GUI dialog to the second user for importing the data structure from the storage location and 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, and displaying the second portlet instance of the second user using the new portlet configuration data.
