[OpenLayers-Users] about text layers

[Alexandre Dube]

Karina,

 You need to have your features served by a "feature server".  MapServer 
can do that for you.  The OGC standard for that is "WFS" so you can try 
to set a WFS server layer in MapServer :
 http://mapserver.org/ogc/wfs_server.html

 and then read it with a OpenLayers.Layer.Vector layer using a WFS 
protocol :
 http://openlayers.org/dev/examples/wfs-states.html

 If you have trouble with the Feature Name Space property, try :
 featureNS: "http://mapserver.gis.umn.edu/mapserver"

  Also, don't forget to "reply-to-all" to have the MailingList aware of 
our discussion.  Others may want to comment too.

Kind regards,

Alexandre
