[jetty-user] Jetty threadpool help

Hi,

   I'm new to Jetty, currently trying to understand different configuration
parameters. One thing I'm interested to understand is how the threadpool
option works for Jetty. Tomcat provides the flexibility to define a
threadpool which will listen to a specific port. For e.g. in Tomcat
server.xml, we can define:

 <Executor name="tomcatThreadPool-dispatch" namePrefix="dispatch-exec-"
        maxThreads="35" minSpareThreads="4"/>

<Connector executor="tomcatThreadPool-dispatch"
               port="19090" protocol="HTTP/1.1"
               connectionTimeout="20000"
               maxPostSize="20971520"
               redirectPort="8443" />

In Jetty, the standard configuration I've seen so far is :

<Set name="ThreadPool">
      <New class="org.mortbay.thread.QueuedThreadPool">
        <Set name="minThreads">10</Set>
        <Set name="maxThreads">40</Set>
        <Set name="lowThreads">5</Set>
        <Set name="SpawnOrShrinkAt">2</Set>
      </New>
    </Set>

Just wanted to know if there's a way to create a threadpool dedicated to a
port ?

Any pointers will be appreciated.

- Thanks
