how to configure jetty to listen to multiple ports

问题

I just want to configure jetty to listen to more than one port. I don't want multiple instances nor multiple webapps, just one jetty, one webapp, but listening to 2 or more ports.

The default way does not support multiple entries:

<Set name="port"><SystemProperty name="jetty.port" default="8080"/></Set>

Thank you for your help!

In your jetty.xml file, add a new connector:

<!-- original connector on port 8080 -->
<Call name="addConnector">
  <Arg>
      <New class="org.eclipse.jetty.server.nio.SelectChannelConnector">
        <Set name="host"><Property name="jetty.host" /></Set>
        <Set name="port"><Property name="jetty.port" default="8080"/></Set>
        <Set name="maxIdleTime">300000</Set>
        <Set name="Acceptors">2</Set>
        <Set name="statsOn">false</Set>
        <Set name="confidentialPort">8443</Set>
    <Set name="lowResourcesConnections">20000</Set>
    <Set name="lowResourcesMaxIdleTime">5000</Set>
      </New>
  </Arg>
</Call>

<!-- new connector on port 8081 --> 
<Call name="addConnector">
  <Arg>
      <New class="org.eclipse.jetty.server.nio.SelectChannelConnector">
        <Set name="host"><Property name="jetty.host" /></Set>
        <Set name="port"><Property name="jetty.port" default="8081"/></Set>
        <Set name="maxIdleTime">300000</Set>
        <Set name="Acceptors">2</Set>
        <Set name="statsOn">false</Set>
    <Set name="lowResourcesConnections">20000</Set>
    <Set name="lowResourcesMaxIdleTime">5000</Set>
      </New>
  </Arg>
</Call>

Then start jetty

java -jar start.jar etc\jetty.xml

Should do what you want.

And if using Jetty in embedded mode, you can open multiple ports in your Java code:

Server server = new Server();
Connector c1 = new SelectChannelConnector();
c1.setPort(8080);
Connector c2 = new SelectChannelConnector();
c2.setPort(8081);
/* ... even more ports ... */
Connector[] ports = {c1, c2 /* ... */};
server.setConnectors(ports);
