HA Singleton Missing Dependencies

[michaelcivicom]

I am running Wildfly 8.2.1 and I have followed the Red Hat guide to create an HA Singleton.

After starting two server nodes from the domain and deploying the HA Singleton, the following errors occur for both nodes:

[Server:server-one]	service jboss.cluster.singleton (missing) dependents: [service jboss.test.ha.singleton.timer]
[Server:server-one]	service jboss.cluster.singleton.registry (missing) dependents: [service jboss.test.ha.singleton.timer]

I am using the HA profile.

Any ideas?

Not sure what happen from your description.

Could you add more information or even your project?

Here is my project https://github.com/michaelpetruzzellocivicom/jboss-javaee-webapp . I am trying to get it to work in a small demo app before I get it into the production application.

I've tried a lot to get this to work, but I'm just not figuring it out. Thank you for the assistance.

You should have a look to Clustering Changes in WildFly 8 topic "Nwe Singleton Service Builder API"

Your code for the Activator seems wrong.

The SingletonService is not public API.  There is a public API for creating singleton service here:

wildfly/clustering/singleton/src/main/java/org/wildfly/clustering/singleton at 8.2.1.Final · wildfly/wildfly · GitHub

The requisite modules will automatically be made available to your application classpath.  This API is further simplified in the latest release (i.e. WildFly 10.0.0.Final), which I strongly encourage you to use.

Thank you Paul and Wolf-Dieter. This is definitely pushing me in the right direction. I am still having issues with container/cache, but I need to spend more time researching before I bring it up here. Thanks again!
