[OpenLayers-Users] Displaying Multiple Markers from Database

[Dipl. Inf. Carsten Eider]

I have solved a similar problem by abusing a GeoRSS-Layer.
A servlet generated the required GeoRSS-Feed, it worked great.
Unfortunatelay some of my feeds contained about 1000 items, where
upto 4 feeds at one time where loaded.

My local system sometimes broke down.
