Re: [jetty-users] The Development LifeCycle
Joakim, many thanks!
 
Your samples are fine!
 
My Program is working fine with Jetty 9 now thanks!
 
You are the best of the best support team! :)

Ah, ok (premature send?).
 
org.mortbay.component.LifeCycle was part of the component lifecycle.
NOT the deployment lifecycle.
 
To add your own component to the lifecycle of the server, just use addBean(mycomponent) against the level you want in the component tree.
 
Example:
 
https://github.com/eclipse/jetty.project/blob/master/jetty-server/src/main/java/org/eclipse/jetty/server/LowResourceMonitor.java#L65
 
import org.eclipse.jetty.util.component.AbstractLifeCycle;
@ManagedObject ("Monitor for low resource conditions and activate a low resource mode if detected")
public class LowResourceMonitor extends AbstractLifeCycle
{
 
 
and the associated XML
 
 
<Configure id="Server" class="org.eclipse.jetty.server.Server">
  <Call name="addBean">
    <Arg>
      <New class="org.eclipse.jetty.server.LowResourceMonitor">

Yes, in Jetty 6 was not AppLifeCycle (deploy based). This is my custom class with name 'AppLifeCycle' (some code from eclipse):

package app.jls;

import java.util.ArrayList;
import java.util.HashMap;

import org.mortbay.component.LifeCycle;

import app.jls.producers.ActionsProducer;
import app.jls.producers.DataProducer;
import app.jls.producers.IncommingsProducer;
import app.jls.producers.LifeCycleLogMessage;
import app.jls.producers.OutgoingProducer;

public class AppLifeCycle implements LifeCycle,NotifiedByMessage {
   // some fields
   // some methods
}

In jetty.xml file:

     <Call name="addLifeCycle">
      <Arg>
        <New class="app.jls.AppLifeCycle">
        </New>
      </Arg>
    </Call>
    <Call name="addLifeCycle">
      <Arg>
        <New class="org.mortbay.jetty.deployer.ContextDeployer">
          <Set name="contexts"><Ref id="Contexts"/></Set>
          <Set name="configurationDir"><SystemProperty name="jetty.home" default="."/>/contexts</Set>
          <Set name="scanInterval">5</Set>
        </New>
      </Arg>
    </Call>

Now, in Jetty 9, can some Isses appear because I use this name (AppLifeCycle) for my custom class ?

Many thanks for answers!
