[Cartoweb-users] SOAP bbox request

Tue Jul 25 22:06:35 EDT 2006

We are working on a college MapServer project with CartoWeb... is a great
productive tool.
As a final task, we are trying to add functionality to search for an
individual parcel and zoom
to it on the map. We are able to retrieve the coordinates from our PostGIS
database but can't get
the SoapClient working and can't figure out how to integrate this function
with the rest of CartoWeb...
i.e. do we have to add/extend a plug-in?

Our third attempt is pasted below. Note the ERROR above the offending line.

Any help greatly appreciated
