Jetty 9: No Spring WebApplicationInitializer types detected on classpath

Question

I am trying to switch from jetty 7.6 to jetty-9.2.1. I made the required configuration changes. But I am continuously getting "No Spring WebApplicationInitializer types detected on classpath" message while initializing the jetty server.

My deployment manager was:

New class="org.eclipse.jetty.deploy.providers.WebAppProvider">

<Set name="monitoredDirName">
  <Property name="cometd.deploy.dir" default="/u/khandela/cometD/webapps_dev/" />
</Set>
<Set name="defaultsDescriptor">
  <Property name="jetty.home" default="."/>/etc/webdefault.xml
</Set>
<Set name="scanInterval">1</Set>
<Set name="extractWars">true</Set>
<Set name="contextXmlDir">
 <Property name="jetty.home" default="." />/contexts
</Set>

In new version "contextXmlDir" is removed. So I also removed from the config. When i run i keep getting the message shown above. Should I add it back, if yes than how ?

And while running I am using: --module=server,jsp,deploy,jmx,resources,websocket,ext,plus,annotations

Below is the detailed messages I get when I run the server:

And that message is a problem because? It is just an info message if your application runs ignore it. — M. Deinum, Jul 08 '14 at 10:03
The info message is not a problem, but why it is saying "No Spring WebApplicationInitializer types detected on classpath" and My question is where and how should I specify "contextXmlDir" ? — Anuj Khandelwal, Jul 08 '14 at 12:39
Because they aren't found hence it is informing you about that. Servlet 3.0 has a `ServletContainerInitializer` for which spring has a `SpringServletContainerInitializer` which looks for `WebApplicationInitializer` instances. Of none found that message appears. Please modify the question to reflect your actual question as currently it is misleading. — M. Deinum, Jul 08 '14 at 12:42
Thanks for the explanation.But if I check the war I can see WebApplicationInitializer in "./WEB-INF/lib/spring-web-4.0.5.RELEASE.jar". Can you please also let me know about "contextXmlDir", How should I configure this in jetty-9.2 — Anuj Khandelwal, Jul 08 '14 at 14:28
That is the interface it doesn't find any implementations of that interface. How to configure the contextXmlDIr no idea, also that wasn't the question you initially asked. Maybe create a new one for that. — M. Deinum, Jul 09 '14 at 05:42

If you configure the org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern attribute in your jetty.xml is going to work. You can find more information about this parameter on the Jetty Documentation: This is a context attribute that can be set on an org.eclipse.jetty.webapp.WebAppContext to control which parts of the container’s classpath should be processed for things like annotation.

<Call name="setAttribute">
  <Arg>org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern</Arg>
  <Arg>.*/foo-[^/]*\.jar$|.*/bar-[^/]*\.jar$|.*/bin/.*|.*/classes/.*|.*/target/.</Arg>
</Call>
