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. 2011-08-24 13:27:21,287 WARN [org.mapfish.print.PDFUtils] - Server returned an error for http://gis.catawbacountync.gov/geoserver/gwc/service/wms?

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