I'm a newbie in web-map application area.
I just found the small application in this tutorial interesting
I am a bit confused, because when I publish a map using GeoServer and OpenLayers, I have to create a layer in GeoServer first and this layer is fixed with a table from PostGIS and then use OpenLayers to call GeoServer to render the map.
- How can the tutor of that tutorial change the data source of the layer depending on the query input by the users?
- It means there are ways to change the data source of one layer on the fly right?
Please advice me how or can anyone tell me where can I download the code of the app in that tutorial.
