Here’s the default configuration for the version of Jetty I use. Note the element is commented.

<!--
<init-param>
      <param-name>cacheControl</param-name>
      <param-value>max-age=3600,public</param-value>
</init-param>
-->

To enable and configure browser cache control, uncomment and edit the param-value as appropriate. The following example instructs the browser to disable all caching.

<init-param>
      <param-name>cacheControl</param-name>
      <param-value>no-store,no-cache,must-revalidate</param-value>
</init-param>

For information on Cache-Control, see RFC 2616, Section 14.9.

Let’s use an example to discover just how easy embedding Jetty can be.  Say we have two servlets, one should be mapped to /service/one and the other /service/two, served on port 8080.

Server server = new Server();
Connector connector = new SelectChannelConnector();
connector.setPort(8080);
server.addConnector(connector);
 
ContextHandlerCollection contexts = new ContextHandlerCollection();
server.setHandler(contexts);
 
Context context = new Context(contexts, "/service");
context.addServlet(ServiceOne.class, "/one");
context.addServlet(ServiceTwo.class, "/two");
 
server.start();
server.join();

That’s it; easy.  For information and more examples on embedding Jetty in your Java application, read Embedding Jetty.
