Did I get it correctly: query 'number of students who study at the university X and come from town Y' should display marker on each university, and marker is labeled with count of students, who come from Y?

comment How to add WFS layer from geoserver to openlayers
Most cases, when WFS requests doesn't work, are caused by browser's same origin policy and you need to set up Proxy or server your JS and WFS from same server:port. But I read you copied your html to geoserver's directory, and that didn't help. As suggested, examine traffic with FireBug. So you can see, whether your requset is made at all and gets answer; and WFS request may contain useful information (error description).

comment ajax not working with postgresql
Agree with Tomfumb's suggestion: at first create PHP file that contains only echo "foo"; so you can determine, whether problem is in your PHP code, or in JavaScript AJAX call. If it works, continue with var_dump $_REQUEST; Also, I would suggest using OpenLayers.Request or jQuery's AJAX functions. Oh, and most important thing: examine request in Firebug.

comment GeoServer GetCapabilities Not Working
You could open your application through Jetty (from localhost:8080), then you won't need proxy. Sorry, haven't done this myself, and can't give any instructions.

comment Split linestring to smaler lines
I don't have correct solution, but problem is: you have WGS coordinates and you don't specify coordinate system. Therefore, those are just planar coordinates, with distances less than 0.01 units between points. Of course there aren't any points added, when you try to segmentize them with 10 units value.

comment Load and display a large number of points using openlayers
Here is example for clustering ~14 000 points (to my knowledge): peatus.ee/#route_search It's Google Maps API + third-party clustering code, not OpenLayers, but you should be able to achieve same result with OL.

comment How can I use CQL in WFS layers in openlayers
Are you using Geoserver? CQL filters don't work with any other WMS service.

comment Append table in PostGIS - Geometry Violation
Do you have pgAdmin? Just look for your table in left pane ('Object browser'), and there's Constraints section. When you are using plain psql, try \d table - but I'm not sure, whether it describes also constraints.

comment Append table in PostGIS - Geometry Violation
You may have POLYGON contraint on sdata.the_geom and therefore can't insert MULTIPOLYGONs. Check out, what is definition for enforce_geotype_the_geom.

comment Append table in PostGIS - Geometry Violation
a) what geometry contraint do you have in sdata? b) what does select geometrytype(the_geom) from s_invalid; say?

comment Spring and OpenLayers conflicts on label rendering?
Usually there is no conflicts, when using jQuery and OL's "${name}" type styling together. For testing, turn 'label': "${name}" into 'label': 'foo' and check, whether labels show up or not.
