Usage Notes
ProfileHasMarker class uses the Profile Marker Manager to determine whether a user profile has a profile marker with the specified key, value, and data property values. In order to check whether a profile has any profile markers, set all three parameters to ANY_VALUE.
For more information on working with marked profiles, see the Using Marked Profiles section in the Using Profile Markers chapter of the Personalization Programming Guide.
Example
In the following example, the servlet bean checks the current user profile for partner profile markers. When none exist, an advertisement displays:
<dsp:droplet name="/atg/markers/userprofiling/droplet/ProfileHasMarkerDroplet"> <dsp:param name="key" value="partner"/> <dsp:param name="value" bean="ProfileHasMarkerDroplet.ANY_VALUE"/> <dsp:param name="data" bean="ProfileHasMarkerDroplet.ANY_VALUE"/> <dsp:oparam name="false"> Purchase your airline tickets with Travel Site A!
