Unable to enable Jetty compression while using Solr 4.4

Question

I am trying to run Solr 4.4.0 using the Jetty distribution that comes along with it. I wish to enable GZip compression on Jetty in order to reduce network traffic. I am trying to run the default "example" that is provided in the distribution. I edited the example/solr-webapp/webapp/WEB-INF/web.xml file to add the following lines under :

<filter>
<filter-name>GzipFilter</filter-name>
<filter-class>org.eclipse.jetty.servlets.GzipFilter</filter-class>
<init-param>
  <param-name>mimeTypes</param-name>
  <param-value>text/html,text/plain,text/xml,application/xhtml+xml,text/css,application/javascript,image/svg+xml</param-value>
</init-param>
</filter>
<filter-mapping>
  <filter-name>GzipFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

However, during startup, I am getting the following exception:

Solr server is starting up and I am also able to query Solr normally. But the results are not getting gzipped. Can someone tell me what's going wrong here?

Answer 1

I suspect you need to add the jetty-servlets artifact to the startup configuration for solr. I don't know how Solr starts up but if they use the start.ini file then you should be able to add something like:

OPTIONS=jetty-servlets
