[Geotools-gt2-users] gt-wfs plug in issue

[Roman I. <rom...@ya...>]

Hello everyone,
I am developing an application that uses the geomajas web gis framework. The application is supposed to access vector datafrom geoserver through wfs. Geomajas uses the geotools wfs plugin to talk to geoserver wfs. I have configured my stores and layers properly in geoserver. My data uses the topp workspace.
I got the following error while trying to use it

>From the logs it seems like for some reason unknown to me the gt-wfs plugin is trying to read the location of the topp uri which is www.openplans.org/topp.the topp uri is just a name space and should not be read at all only just the gml features. I don't know if this is a bug. My wfs get capabilities url is this
WFSDataStoreFactory:GET_CAPABILITIES_URL: http://localhost:8080/geoserver/ows?service=WFS&amp;VERSION&#61;1.0.0&amp;request&#61;GetCapabilities
is this url wrong ? In ur example on the wfs plug in page (http://docs.codehaus.org/display/GEOTDOC/WFS+Plugin) the url specified there was http://localhost:8080/geoserver/wms?REQUEST=GetCapabilities. I presume this was a mistake.

Has anyone experienced this before ? how was it resolved ?
I would really appreciate it if I can get help on this. I am using geoserver 2.0.2 and geotools 2.6.3.
Cheers,
Roman.
