To configure advanced features of Jetty you may use jetty xml style configuration files. To make Pax Web aware of your Jety configuration files you will have to use fragments. Be aware that fragment bundles are not yet fully supported on all OSGi implementations!

As an example, it’s shown enabling JMX in Jetty.

OSGi-Bundle Fragment way

To customize Jetty used by Pax Web Service follow instructions: Create a bundle fragment for Pax Web Service bundle for example:

Manifest-Version: 1.0
Fragment-Host: org.ops4j.pax.web.pax-web-jetty-bundle (1)
Bundle-Version: 0.1
Bundle-Name: My Jetty config
Bundle-ManifestVersion: 2
Bundle-SymbolicName: my.jetty_config
1 the required line in the manifest.
If the version you are using is the non bundled version of jetty bundle you should use org.ops4j.pax.web.pax-web-jetty instead of org.ops4j.pax.web.pax-web-jetty-bundle as value of Fragment-Host.

Put jetty.xml in root directory of fragment. For example, take a look at a simple example fragment bundle from Pax Web that will add an additional connector on port 8383.

Add fragment to your start configuration If you have logging at DEBUG level enabled, when you start, you should see in logs something like this:

DEBUG  pax.web.service.internal.JettyServerImpl  - starting JettyServerImpl{}
DEBUG  pax.web.service.internal.JettyServerImpl  - configure using bundleresource://100/jetty.xml
Note that the url ``bundleresource://100/jetty.xml'' from above is just an example as the url is framework specific

Using external jetty.xml file

Sometimes it’s needed to have a much more easier way of configuring the underlying Jetty server. An external located jetty.xml file can be used for configuring the jetty server. This can be activated by setting the following property for Pax Web


For more details on how to configure the Jetty Server take a look at the official jetty.xml configuring page.

Adding specialized ContextHandlers

If you want to add specialized ContextHandlers to the jetty server you have to be careful not to break the way Pax Web works. So Instead of defining a new Collection of Handlers in the jetty.xml you need to add your specialized ContextHandler to the existing Collection.

Here is an example where the jetty Default Servlet is used to server static content from the file system.

  <Get name="handler">
    <Call name="addHandler">
        <New class="org.eclipse.jetty.servlet.ServletContextHandler">
          <Set name="contextPath">/app</Set>
          <Set name="resourceBase">/path/to/your/share</Set>
          <Call name="addServlet">

Using Handler and Connectors as Services

The Following described way of working is only valid starting with version - 4.1.0

All possible Handler or Connector configurations to Jetty through the jetty.xml file can now be registered as Services. With this it’s possible to register the previously made sample of specialized ContextHandler as service.

ContextHandler ctxtHandler = new ContextHandler();
ResourceHandler resourceHandler = new ResourceHandler();

ServiceRegistration<Handler> registerService = bundleContext.registerService(Handler.class, ctxtHandler, null);
