[ http://jira.jboss.com/jira/browse/JBREM-93?page=comments#action_12316828 ] Tom Elrod commented on JBREM-93: ---------------------------------
I don't think this is documented anywhere. The real problem lies in that there can be many exceptions that are raised that have nothing to do with the actual callback handler receiving the callback (i.e. network connection problem). Another major issue is that the client may get the callbacks by polling, so even if the client has a problem processing the callback, there is no way to provide this feedback to server (and is up to client if is push or pull, so no way for server side to rely on this behavior). I would prefer to change the HandleCallbackException than return an Object from the handleCallback() method because of the forementioned problem of not knowing if is push or pull (as would always have to return some default value if was pull, like null, since would not be able to get it from the client till sometime later). So if I added something to HandleCallbackException like getUserException() which would return original exception thrown by client (if there was one, otherwise return null), would that work? Also, would it be useful to provide a way of knowing if CallbackHandler is using pull or push model? Maybe a use case would help me understand what you are after a little better. > Callback handler returning a generic Object > ------------------------------------------- > > Key: JBREM-93 > URL: http://jira.jboss.com/jira/browse/JBREM-93 > Project: JBoss Remoting > Type: Feature Request > Components: callbacks > Reporter: Ovidiu Feodorov > Assignee: Tom Elrod > Priority: Optional > > > InvokerCallbackHandler.handleCallback() returns void.
