    Migration of jboss-4.2.3.GA MBean wrapping Dumpster SMTP service to wildfly-8.1, Best Practices / Tips

    Juergen H Newbie

      Hi, I'm currently in the process of migrating a simple web-application from jboss-4.2.3.GA to wildfly-8.1 (basically used as a servlet container)


      I have a production and test environments.


      I'm using Dumpster SMTP http://quintanasoft.com/dumbster/ to catch emails sent in test environments


      To this end, I created a DumpsterSimpleSmtpServerService extends ServiceMBeanSupport in jboss-4.2.3.GA. The class is available via <jboss-4.2.3.GA>/server/<config>/lib/MyDumpsterService.jar

      I also deploy - in test environments only - a <jboss-4.2.3.GA>/server/<config>/deploy/com.dumbster.smtp-service.xml:


              <attribute name="port">8625</attribute>
              <depends optional-attribute-name="threadPoolMBean" proxy-type="attribute">jboss.system:service=ThreadPool</depends>

      It's basically a service start / stop with a port number and a Thread resource.


      Now my question is how to best mirgrate this setup to wildfly-8.1?


      I read that jboss-service deployments still work:


      So I could put my jar and service.xml into a .sar and deploy it in test environments. Seems the easiest thing to do with least changes needed.

      But I'd like to get rid of legacy stuff if possible. Also I don't know where to get a "jboss.system:service=ThreadPool" from. I don't want to simply do "new Thead" but use some server managed factory instead.


      I thought about extending wildfly-8.1 subsystems with my own custom dumpster-smtp subsystem


      Though on first read this seems to involve lots of stuff to do for a simply thing as my service.


      I also thought to create a dumpster-smtp server application ear, using JAVAEE concurrency support to have it run in background listening to it's socket.

      But again, seems a bit of overkill creating a fully blown app.


      Any recommendations for migrating my jboss-4.2.3.GA single class MBean service + deployment descriptor service.xml to wildfly-8.1 ?
