I am creating a leaflet app. For this I have to use a Geoserver.

I found that CORS was not enabled, because I get this error message: Reason: CORS header 'Access-Control-Allow-Origin' missing: https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS/Errors/CORSMissingAllowOrigin

enter image description here

To enable CORS filter I commented out the following in web.xml file in webapps/Geoserver/WEB-INF like explained here: https://docs.geoserver.org/latest/en/user/production/container.html and here Can't access GeoServer after CORS filter

Now it looks like this:

   <!-- Uncomment following filter to enable CORS -->
   <filter>
        <filter-name>cross-origin</filter-name>
        <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
       <init-param>
           <param-name>chainPreflight</param-name>
           <param-value>false</param-value>
       </init-param>
       <init-param>
           <param-name>allowedOrigins</param-name>
           <param-value>*</param-value>
       </init-param>
       <init-param>
           <param-name>allowedMethods</param-name>
           <param-value>GET,POST,PUT,DELETE,HEAD,OPTIONS</param-value>
       </init-param>
       <init-param>
           <param-name>allowedHeaders</param-name>
           <param-value>*</param-value>
       </init-param>
    </filter>

...

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

Adding the filter will cause the Geoserver/Jetty service to not start proper. This is my error message:

2019-10-24 11:19:53.444:INFO:oejs.Server:main: Started @28862ms

I checked jars like explained here Enabling CORS in GeoServer (jetty)?

enter image description here

Everything looks OK for me, but then I searched for the exact error message:

NO JSP Support for /wms, did not find org.eclipse.jetty.jsp.JettyJspServlet

I read this: https://stackoverflow.com/questions/26217143/embedded-jetty-server-no-jsp-support-for-did-not-find-org-apache-jasper-ser and I think there is missing something.

But I do not understand what is missing. here exactly I should put which JAR? I do not create a Java application. I only want to access the geoserver remotely.

I am happy about any help

For a first solution I put the line

set geoserver.xframe.shouldSetPolicy=false 

in startup.bat in the folder geoserver/bin So I can show the data in an Iframe. But I need to manipulate some texts. So I need to enable CORS.

Edit: Whole error message:

    your error is further up the log file (and unrelated to the JSP warning) - we need to see the block above at org.eclipse.jetty.start.Main.main(Main.java:77) – Ian Turton Oct 24 at 10:02

It seems that the version of Jetty being shipped with GeoServer 2.15 now includes the required jetty-servlets-x.jar and it becomes confused if you add another copy to the class path. I'm not sure if this is a change to Jetty or just to the version GeoServer packages.

So the fix is to delete webapps/geoserver/WEB-INF/lib/jetty-servlets-9.4.12.v20180830.jar and restart Jetty.

I have updated the answer to this question (and cross linked for anyone else seeing this issue).

  • Thank you Ian. Your are right. Deleting the file webapps/geoserver/WEB-INF/lib/jetty-servlets-9.4.12.v20180830.jar and restart Jetty solved my problem. After reading all hints, I was sure that this file must also be in this directory. I probably did too much :) – astridx Oct 24 at 16:05
