[Geoserver-users] VPF plugin bug?

Joshua_Foster · November 9, 2007, 6:53pm

Is there any work being done on the VPF plugin? I am not able to make a
WMS request on any VPF dataset more than once. The first request goes
fine, as shown here:

17157625 [INFO] org.vfny.geoserver.servlets.AbstractService - handling
request:

GetMap Request

version: 1.1.0

output format: image/png

width height: 544,790

bbox: Env[-77.10498809814453 : -77.09300994873047, 38.407073974609375 :

layers: openumi:COASTLINE__SHORELINE_LINE

styles: line

17160312 [INFO] org.vfny.geoserver.servlets.AbstractService - Service
handled

However the very next request (for example if I zoom out or pan around)
and all subsequent requests fail:

At this point any further requests for VPF will throw the same error.
If I restart GeoServer, I can again make a successful VPF request -
once. Any ideas about what might be causing this?

Thanks,

Joshua Foster

No, unfortunately no one has worked on the VPF plugin for awhile, and it never really reached a very stable state. I'd recommend converting to shapefile or postgis.

best regards,

Chris
