Hi,

you'll find plenty of samples at the Pax-Web GitHub project. [1]
If you want to use the HttpService as you've done before, you'll just need
to register a compression filter as I've send you before. [2]
You'll find a sample on how to register filters with Pax-Web at [3].
Another way of using filters is to use a WAB [4]. There you need to
register your compression filter also, as JB mentioned first.
There is nothing directly to be configured for Jetty.

regards, Achim

I created 'jetty-web.xml' and 'webdefault.xml' in dsp-k-1.5.0\etc folder

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC &quot;-//Jetty//Configure//EN&quot;
&quot;http://www.eclipse.org/jetty/configure.dtd&quot;>

<Configure class="org.eclipse.jetty.webapp.WebAppContext">	
	<Set name="defaultsDescriptor">webdefault.xml</Set> 
</Configure>

and 'webdefault.xml'

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">
	
	<filter>

I checked the Jetty documentation, it's quite simple to support gzip
compression,
you just need a filter for it. So add a filter to your Application
according to the documentation of jetty [1].

Hi,

You might try to add a general rule to the jetty.xml. Or move your project
into a wab project.

Hi,

You have to use the GzipFilter.

You have to provide a web.xml including something like:

   <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>

Regards
JB
