-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi AS developers, I am exploring the behavior of parallel initialization of web application in EAR. More concretely more than one web application in EAR. I know that spec doesn't define the initialization order of EAR submodules, but the parallel initialization of web application is new in AS7 and this breaks the backward compatibility for existing enterprise applications with multiple wars inside. New Java Enterprise application 6 configuration setting <initialize-in-order>true</initialize-in-order> set up in application.xml can enable proper initialization flow, but without it is not possible to deploy. Could somebody shed light on parallel web applicaiton init? Original forum post https://community.jboss.org/message/635123 And details could be seen also at https://issues.jboss.org/browse/JBSEAM-4856?focusedCommentId=12662448&...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Well, I would like a confirmation that this behavior is by design and if application requires specific order you have to do it by configuration in application.xml. So for every such old application you need to do a migration. I haven't found any JBoss AS 7 documentation about it so it was my question that I got it correctly ;-) Dne 30.1.2012 23:10, Stuart Douglas napsal(a): > I'm not really sure what you are asking here, as far as I have see you have answered your own question, just use<initialize-in-order>true</initialize-in-order> to get non-parallel startup. > > Stuart > > > > On 31/01/2012, at 8:59 AM, Marek Novotny wrote: > > Hi AS developers, > > I am exploring the behavior of parallel initialization of web > application in EAR.

I think we owe some Warning or Note in documentation at least in Migration part to our users ;-). On 01/30/2012 11:27 PM, David M.
