[jboss-jira] [JBoss JIRA] (WFLY-776) Inject POJO to MBean by using <inject bean="XXX"> in jboss-service.xml does not work in SAR

[Romain Pelisse (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13025434#comment-13025434 ] 

Romain Pelisse commented on WFLY-776:
-------------------------------------

Regarding the two technical issues raised by Tomasz (and I've discussed with him over IRC):

1) dependency between the mbean service and the pojo service seems to be OK - it's not far fetch to think that MBean would need to access POJO just for this purpose (looking up dependency)

2) rather than chaning the XML syntax, we could change the content of the bean attribute, by adding a prefix:

{code:xml}
 <mbean code="com.redhat.jboss.support.HelloService"
         name="example:type=HelloService,service=Hello">
     <attribute name="Message">Hello!!</attribute>
     <attribute name="Task"><inject bean="pojo:myTask"/></attribute>
  </mbean>
{code}

Which leads to no prefix, default behavior, prefix load some factories/resolver based on the prefix. On top of not arming the current syntax, it also reuse an usual practice (like URL) to specifiy other mechanism to inject dependency.
