[GIS] Geoserver won’t start after setting up CORS (no jetty installed?)

corsgeoserverjetty

I tried to enable CORS by uncommenting the necessary lines in the web.xml file of geoserver. However, I didn't know that I also had to make sure having the correct jetty servlets jar file in my WEB-INF/lib folder (as described in this post). As the CORS didn't work I thought I had to restart tomcat, but since I did that I got an error that jetty couldn't be found:

Exception starting filter cross-origin java.lang.ClassNotFoundException: org.eclipse.jetty.servlets.CrossOriginFilter

Now I tried to find out which jetty version I use to get the correct servlets jar file, but somehow I cannot find any installation of jetty in my geoserver folder. I installed geoserver with the war file and running it on tomcat. And as I understood jetty comes together with geoserver, so it should exists…

What should be my next step now?

EDIT: geoserver version is 2.13.2

If you are using tomcat then any reference to jetty is a red herring. Try following these instructions for tomcat.

[GIS] How to add Cross Origin Filter for Jetty in GeoServer on Mac

It's very unlikely that you can add random jars to your jetty install and expect it to work - which seems to be case here.

The easiest solution (if you really can't be bothered to add a proxy script) is to download the latest version of jetty and add the GeoServer war file to it and then modify the web.xml file.

[GIS] Enabling CORS in GeoServer (jetty)

Edit the webapps/geoserver/WEB-INF/web.xml file. There are two references to CORS in this file:

<!-- Uncomment following filter to enable CORS -->
<filter>
  <filter-name>cross-origin</filter-name>
     <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
  </filter>

and

<!-- Uncomment following filter to enable CORS -->
<filter-mapping>
   <filter-name>cross-origin</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>

You must uncomment both blocks (that is remove  from the filter and filter-mapping blocks.

Then when you restart Jetty you can test that everything is working by using a command like:

curl -v -H "Origin: http://example.com" http://astun-desktop:9080/geoserver/wfs\?service\=WFS\&version\=2.0.0\&request\=GetFeature\&typenames\=sf:bugsites\&filter\=%3Cfes:Filter%20xmlns:fes\=%22http://www.opengis.net/fes/2.0%22%3E%3Cfes:ResourceId%20rid\=%22bugsites.3%22/%3E%3C/fes:Filter%3E

which if all is well will give a result like:

> User-Agent: curl/7.35.0
> Host: astun-desktop:9080
> Accept: */*
> Origin: http://example.com

Update 24th Oct 2019

It it is no longer necessary to add the following jar to GeoServer (at least with versions 2.13.x and later) and it will cause an error. I'm leaving this note here for people fighting older versions.

Add the Jetty-Utility Servlets Jar to match the version of Jetty - for current versions of GeoServer (2.15.x) it is 9.4.12.v20180830, copy this to webapps/geoserver/WEB-INF/lib inside the geoserver-2.15.0 directory (or wherever you unpacked the zip file).
