In general, the OpenLayers list will be better at helping you understand why OpenLayers behaves in a certain way. Once you've narrowed it down to a specific URL failing -- as you've done here, thank you for that -- you'll probably be able to get more from a GeoServer list than from the OpenLayers list. > It returns a file called "wms" that contains this error message: > > <?xml version="1.0" encoding="UTF-8" standalone="no"?><!DOCTYPE > ServiceExceptionReport SYSTEM > "http://schemas.opengis.net/wms/1.1.1/WMS_exception_1_1_1.dtd";> > <ServiceExceptionReport version="1.1.1" > <ServiceException> > org.xml.sax.SAXParseException: Content is not allowed in prolog. > org.xml.sax.SAXParseException: Content is not allowed in prolog. > Content is not allowed in prolog. > </ServiceException></ServiceExceptionReport> 1. Check to make sure that GeoServer is actually reaching maps.massgis.state.ma.us . It is possible that there is a proxy or something getting in the way, preventing GeoServer from etching your SLD. 2. Perhaps put a prolog on the SLD file? <?xml version='1.0' ?> Other than that, it sounds like a bug. I'd try the GeoServer list and see if anyone there has any advice, personally... -- Chris > The layer massgis:DCR.ROADS_TRAILS_POINT and the SLD file > http://maps.massgis.state.ma.us/dcr/trails/sld/DCR.ROADS_TRAILS_POINT--T > ype_Max_18000.sld.xml work fine in a GetMap request [see > http://maps.massgis.state.ma.us/dcr/trails/DCR_RoadTrail12.html - you > need to zoom in to see the point layer].
