Hi all I am trying to get a WMS layer on my cesium globe. Below is the code I am using. When I look at the network tabs I do see the request going through all at 200 and when I use the links on the requests they do work; however, it says their file size is 0kb and I receive this error :
An error occurred in "p": Failed to obtain image tile X: 0 Y: 0 Level: 1. etc.
var viewer = new Cesium.Viewer('cesiumContainer');
var provider = new Cesium.WebMapServiceImageryProvider({
url : url',
layers : 'bm'
});
viewer.imageryLayers.addImageryProvider(provider);
For me it was a CORS issue. If you add the filters in geoserver/webapp/geoserver/WEB-INF/web.xml
<!-- Uncomment following filter to enable CORS -->
<filter>
<filter-name>cross-origin</filter-name>
<filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
</filter>
<!-- Uncomment following filter to enable CORS -->
<filter-mapping>
<filter-name>cross-origin</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
and add the jetty servlets in geoserver/webapp/geoserver/WEB-INF/lib it will fix this issue. Download for the servlets is here: http://repo1.maven.org/maven2/org/eclipse/jetty/jetty-servlets/
See https://gis.stackexchange.com/questions/210109/enabling-cors-in-geoserver-jetty for more info.
