[jetty-users] Can jetty have a hook after the server is ready?

[Lin Ren]

Hi all,

 

I’m currently trying my project on Jetty standalone mode.

 

I wrote a BootstrapServerService, which annotated by “@ManagedObject” and extends org.eclipse.jetty.util.component.AbstractLifeCycle.

 

The BootstrapServerService is now added into Server as a bean (in jetty.xml):

 

    <Call name="addBean">

      <Arg>

        <New class="com.bea.wlcp.wlng.core.wls.BootstrapServerService"/>

      </Arg>

    </Call>

 

Then the BootstrapServerService is started before deployed application is activated, just as my expected.

 

However, in the BootstrapServerService, there is logic to get the RMI repository and bind local object:

 

        final Registry registry = LocateRegistry.getRegistry();

        registry.bind(fullJndiName, stub);

 

It fails because the RMI service is NOT started yet. So I tried to single out the bind logic and trying to find a hook from Jetty to execute this logic after the RMI is ready, but so far I’m not able to find it out.

 

Can anyone give advisement?

 

Thanks!

See
https://github.com/eclipse/jetty.project/blob/jetty-9.4.x/jetty-home/src/main/resources/etc/jetty-started.xml

Which sets up a LifeCycle Listener that simply writes a file saying it
started.

The implementation of LifeCycle could also help you.
