    Is there way to ensure that one subsystem is fully initialized before another one?

      I m trying to use JDBC_PING protocol in jgroups on WF10.0.  I use datasource_jndi_name property to refer to our of data sources configured in my standalone.xml file.  It works most of the time... but some times I get exception like this:

      I could be wrong... but the way I interpret this - my data source have not been fully initialized before JGroup's JDBC_PING protocol tried to use it.

       

      Am I correct in my diagnosis? How can I address this issue?

       

      Your help would be highly appreciated,

       

           Cheers, Andrei
