Migration of jboss-4.2.3.GA MBean wrapping Dumpster SMTP service to wildfly-8.1, Best Practices / Tips
work_registries Jul 3, 2014 9:27 AMHi, 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:
<server> <mbean name="dumpster:service=SmtpServer" code=DumpsterSimpleSmtpServerService" xmbean-dd="xmdesc/DumpsterSimpleSmtpServerService-xmbean.xml" > <attribute name="port">8625</attribute> <depends optional-attribute-name="threadPoolMBean" proxy-type="attribute">jboss.system:service=ThreadPool</depends> </mbean> </server>
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
https://docs.jboss.org/author/display/WFLY8/Extending+WildFly+8
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 ?
