Thanks Julian. The Tomcat option is not really an option at the moment since I will need to start from scratch and there is another learning curve. Cheers.

Hi Jair, Sorry, I have no experience modifying a Jetty setup. My only suggestion is that you check the logs and work from there. Otherwise, consider moving to a setup based on Tomcat. /julian -----Oprindelig meddelelse----- Fra: Jair Santos [mailto:jsa...@gm...] Sendt: 8. oktober 2015 00:19 Til: 'GeoServer Mailing List List' Emne: Re: [Geoserver-users] How to deal with XMLHttpRequest in Geoserver? Hi Julian, I am getting more confused about this. I am trying to follow the instructions from http://wiki.eclipse.org/Jetty/Feature/Cross_Origin_Filter , but it is still not working. I didn't have jetty under C:\Program Files\GeoServer\webapps\geoserver\WEB-INF\lib, so I copied the files jetty-6.1.8.jar and jetty-util-6.1.8.jar from C:\Program Files\GeoServer\lib. Then I included in C:\Program Files\GeoServer\webapps\geoserver\WEB-INF\web.xml the lines <filter-mapping> <filter-name>cross-origin</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> I rebooted the server just in case, and then geoserver stopped working. The service geoserver was still running but when I go to the browser with http://localhost:8080/geoserver/web/ I get http error 503. Any comments will be appreciated. Thanks.

Aha, in that case, you are running GeoServer inside a Jetty server which is located at something like C:\Program Files (x86)\GeoServer 2.7.0 Somewhere in here is where you need to make the modification. I have not tried this myself, but from http://wiki.eclipse.org/Jetty/Feature/Cross_Origin_Filter, I am guessing that you need to modify C:\Program Files (x86)\GeoServer 2.7.0\webapps\geoserver\WEB-INF\web.xml Good luck, /julian -----Oprindelig meddelelse----- Fra: Jair Santos [mailto:jsa...@gm...] Sendt: 6. oktober 2015 22:33 Til: 'GeoServer Mailing List List' Emne: Re: [Geoserver-users] How to deal with XMLHttpRequest in Geoserver?

Well, I downloaded the windows binary and installed geoserver as a windows service using the wizard with default settings. Right now I am creating an openlayers app that is running as the default (port 80) web site in the same server. This openlayer web app is trying to access geoserver with: new ol.layer.Vector({ source: new ol.source.Vector({ url: 'http:// 174.5.61.148:8080/geoserver/geid_ws/kml?layers=geid_ws:bmid-parcels', format: new ol.format.KML() }) }), Isn't that the right way? Thank you.

Thank you Julian, I did exactly that. So the configuration in the server is rather simple. I've just included a line in the webconfig file , that is <system.webServer> <httpProtocol> <customHeaders> <add name="Access-Control-Allow-Origin" value="*" /> </customHeaders> </httpProtocol> </system.webServer> It made no difference whatsoever. Then I realized that this change will make IIS send the header, and in my case it is Geoserver that will format and send the response not IIS. The openlayer program is calling Geoserver with 'http:// 174.5.61.148:8080/geoserver/geid_ws/kml?layers=geid_ws:bmid-parcels'. I am really confused about how this work even after reading the tutorial and examples of CORS.

Hi Jair, CORS has nothing directly to do with GeoServer, since GeoServer runs inside an application server. If I read you correctly, and you are running GeoServer inside IIS, then you need to find out how to configure CORS on IIS. I have never done this myself, but Googling "cors on iis8" turns up lots of links which appear to be helpful.

Hi all, I am returning to this thread since I've been away for a month and the problem was still here waiting for me. I've been trying to create a layer with new ol.layer.Vector({ source: new ol.source.Vector({ url: 'http:// 174.5.61.148:8080/geoserver/geid_ws/kml?layers=geid_ws:bmid-parcels', format: new ol.format.KML() }) }), The server is responding with XMLHttpRequest cannot load http:// 174.5.61.148:8080/geoserver/geid_ws/kml?layers=geid_ws:bmid-parcels. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http:// 174.5.61.148' is therefore not allowed access. If I understood well geoserver itself will have to format the response including a header containing Access-Control-Allow-Origin = http:// 174.5.61.148:80. Am I right? I truly believe that there is another solution (other than setup a proxy as suggested by Stefano) but unfortunately I couldn't find out. My environment is MS Server 2012, IIS 8, Geoserver 2.7.1.1 Any help will be very much appreciated. TIA JJ.

Hi Jair, CORS is something that you configure on the server side, wrapping the request client-side is not going to take you anywhere. I don't know what your environment is, but if you happen to be running GeoServer on Tomcat 7, this StackOverflow question might help you: http://stackoverflow.com/questions/22363192/cors-tomcat-geoserver Another option you have is to setup a proxy on the machine where your web app is deployed, e.g. using Apache HTTPD. Also this neat little open source project from the company I work for (GeoSolutions) might be worth a look: https://github.com/geosolutions-it/http-proxy.

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http:// 174.5.61.148' is therefore not allowed access." This means that Geoserver is not returning the proper "Access-Control-Allow-Origin" in the response. Therefore I have to deal with CORS (Cross Origin Resource Sharing). Basically I have to embed the geoserver request in a javascript code such as function createCORSRequest(method, url) { var xhr = new XMLHttpRequest(); ..... Where url = http:// 174.5.61.148:8080/geoserver/geid_ws/kml?layers=geid_ws:prv_stns Any ideas?
