[Users] geoext Printprovider bad request

[Matt Priour]

You can use gwc’s wms, just not as a single tile layer:
tileSize: new OpenLayers.Size(256,256)
is a _required_ config property of the layer(s) you are trying to print.

Your other option is to use an XYZ layer type with your gwc layers.

Subject: [Users] geoext Printprovider bad request

I did not know if this list or the geoserver list would be a better forum for this question. I decided to start here.

 

After adding layers to my map from geowebcache and generating a pdf with the Printprovider  the gwc layers were not showing up in the generated pdf.

My straight up wms layes etc, were printing fine as usual.

 

In my geoserver logs I found the following information that indicated a bad request.

I did not know why it was a bad request but I was suspicious of the HEIGHT and WIDTH

 

Pasting the url into my browser confirmed that by returning the error

400: The requested tile dimensions 694x667 do not match those of the grid set (256x256)

http://gis.catawbacountync.gov/geoserver/gwc/service/wms?BBOX=-9079690.0%2C4218281.5%2C-9006310.0%2C4294718.5&HEIGHT=694&WIDTH=667&TRANSPARENT=true&map_resolution=100&VERSION=1.1.1&FORMAT=image%2Fpng&TILED=true&SERVICE=WMS&format_options=dpi%3A100&LAYERS=ncgroup&REQUEST=GetMap&STYLES=&SRS=EPSG%3A900913

 

 

OK great. What can I do to resolve the issue? Can I use my gwc layers with the printProvider? Do I have deeper issues?
