[Installation, Configuration & DEPLOYMENT] - Looping on Socket Exceptions
by glad01
I have been experiencing socket exceptions that throw the app server into unrecoverable looping. I have been able to recreate this running on 4.2.1.GA with messaging 1.3. I have also seen this on 4.0.5.GA and 4.0.3sp1 that are running different applications. These servers are running on widows XP and Server2003. This does not occur under load it happens when we slow the transaction rate down.

[JBoss Seam] - Re: Semantics of @Name, @DataModelSelection
by djfjboss
Many thanks once again for your help.
I'm finding progress with Seam frustratingly slow. It sounds like a very powerful technology that should be a great productivity aid but, although the examples look straightforward, when I come to try them there are hidden subtleties and inconsistencies that continue to trip me up (perhaps they're not so straightforward!).
In addition there are oddities such as the commented out @RequestParameter annotation that's not even explained in the book. I'm reading Yuan/Heute and Nusairat in parallel, neither is the best text book I've ever encountered - the RoR books put them both to shame.
Do you have any suggestions for better sources of understanding? A clear explanation of the underlying concepts and the semantics of the annotations would hopefully go a long way to dispelling some of my confusion and frustration.

[JBoss jBPM] - Re: what is the difference between swimlane and swimlaneInst

And btw, I did not tell you to RTFM (although source/testcases are imo part of that) but the usage of these fields/methods often really becomes more clear and helps you to understand more of jBPM. And I did not even say it was OBVIOUS, at least it is not to me, but before the I dive into the code to TRY TO HELP YOU, I had hoped that you would provide me with some more INFO, but clearly you do not.

[Beginners Corner] - Re: Rather simple but doesn't work
by woo37830
Did check this and confirmed that I did "default" installation. Uninstalled and reinstalled using EJB3 option. This allowed seam gen to create project and deploy it. It created a login page, but when I did the seam generate-entities, it created new classes for accessing the tables, but upon restarting the server, I get an error during startup of
10:25:57,996 ERROR [URLDeploymentScanner] Incomplete Deployment listing:
--- MBeans waiting for other MBeans ---

And in the browser,
Cannot get value for expression '#{queueList.firstResult}'
How do I "fix" this? For this to be useful, it should handle these automatic generation things correctly.
