How to get mbean-based SAR that deployed in EAP 5.2 to deploy on EAP 6.x?

Solution Unverified - Updated

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP)
    • 6.x

Issue

A SAR project was created with 2 mbean classes configured in the jboss-service.xml. The attached project is test.sar.

The 2 mbean classes (TestValueFactory & OtherValueFactory) are configured in the jboss-service.xml file. In accordance with our wishes, the TestValueFactory mbean is configured in this file such that it gets configuration information information from the OtherValueFactory mbean (done using the tag). Please note that the attribute is used in the TestValueFactory mbean specification to mark the dependency.

Deployment of test.sar worked in JBoss EAP 5.2 but failed in JBoss EAP 6.4.0 with the following error:

The attached test.sar file (called test_sar.tar should be renamed to test.sar before extracting) includes the jboss-service.xml used along with jboss-service.xml files for EAP5 and EAP6.

Resolution

The configuration in test.sar for EAP6 appears to be correct. There is a bug in EAP 6.x which prevents the successful deployment of this mbean test case. This bug was addressed and resolved in This content is not included.Bugzilla 1329314

To resolve this issue, download the attached Patch.zip file which contains the patch so that test.sar deploys in EAP 6.x.

To apply this individual patch, follow the steps outlined in How do I apply individual or cumulative patches in JBoss EAP 6.2 and beyond [1]?

To rollback this individual patch if installation has unexpected consequences, follow the steps outlined in How do I rollback individual or cumulative patches in JBoss EAP 6.2 and beyond [2]?
