[seam-issues] [JBoss JIRA] Commented: (JBSEAM-2286) MDB activated too early to use Seam components as a standard EJB

    [ https://jira.jboss.org/browse/JBSEAM-2286?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12539445#action_12539445 ] 

Marcel Sebek commented on JBSEAM-2286:
--------------------------------------

On jboss 5 and ear type of deployment, I have been successful with the following workaround: each MDB annotate with @org.jboss.ejb3.annotation.Depends({"jboss.web.deployment:war=/my-war-name"}).

> As specified in the forum reference I have an MDB which uses a SLSB (also declared as Seam component) with business logic. If I deploy the application and there are already messages in the queue I get the following exception:
> javax.ejb.EJBTransactionRolledbackException: java.lang.IllegalStateException: Attempted to invoke a 
> Seam component outside the an initialized application

>         at $Proxy111.onMessage(Unknown Source)
> Looks like the MDB processing the message before Seam is initialized? 
> This forces me to undeclare the SLSB as a Seam component and (potentially) duplicate business logic if I want to re-use the same functionality of the SLSB in Seam.
> I could use the solution from http://www.jboss.org/?module=bb&op=viewtopic&t=100946 but then it would force me to use vendor-specific API.
