Re: [jetty-users] Start up order of contexthandlers / jetty maven plugin app?
Hi Jan,

Thank you for the quick reply, that was exactly what I was looking for! :)

The portal app still does not pick up my own portlets, but now I can cross the jetty config off the list and figure out the next piece of the puzzle.

Chris,

If you use a jetty xml file and set up the handler structure in there,
and add in the webapp you want started first, the webapp that is the
subject of the jetty:run command will always be appended to the
context handler collection last. The context handler collection starts
up the contexts serially, in the order they appear in the collection.

Testing with jetty-9.1, here's an example jetty.xml file:

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN"
"http://www.eclipse.org/jetty/configure_9_0.dtd">
<Configure id="Server" class="org.eclipse.jetty.server.Server">

    <Set name="handler">
      <New id="Handlers"
class="org.eclipse.jetty.server.handler.HandlerCollection">
        <Set name="handlers">
         <Array type="org.eclipse.jetty.server.Handler">
           <Item>
             <New id="Contexts"
class="org.eclipse.jetty.server.handler.ContextHandlerCollection"/>
           </Item>
           <Item>
             <New id="DefaultHandler"
class="org.eclipse.jetty.server.handler.DefaultHandler"/>
           </Item>
         </Array>
        </Set>
      </New>
    </Set>


    <Ref refid="Contexts">
      <Call name="addHandler">
        <Arg>
          <New class="org.eclipse.jetty.webapp.WebAppContext">
            <Set name="contextPath">/other</Set>
            <Set name="war">other.war</Set>
          </New>
        </Arg>
     </Call>
    </Ref>

</Configure>

And here's the pom.xml snippet:
     <plugin>
        <groupId>org.eclipse.jetty</groupId>
        <artifactId>jetty-maven-plugin</artifactId>
        <version>9.1.0.v20131115</version>
        <configuration>
          <jettyXml>jetty-main.xml</jettyXml>
          <webApp>
            <contextPath>/test</contextPath>
          </webApp>
        </configuration>
      </plugin>

I've added ServletContextListeners for both webapps that just prints
out "contextInitialized" along with the ServletContextEvent, and
here's the startup log output  confirming /other was started before
/test:

2013-12-03 10:31:25.537:INFO:oejs.Server:main: jetty-9.1.1-SNAPSHOT

So that confirms things are starting up in the right order.

I think you'll have to dig a bit into the portal application to see
how it completes its startup. Perhaps you could try running it in
maven using the jetty:deploy-war goal (see
http://www.eclipse.org/jetty/documentation/current/jetty-maven-plugin.html#deploy-war-running-pre-assembled-war
for how to configure your pom) to check if it deploys ok by itself.

cheers
