Application.xml vs sun-application.xml

I'm developing a JSF2 application using Glassfish which contains some EJB's; is there a reason I should use sun-application.xml versus the standard application.xml file?

I would like to deploy my application as an exploded EAR. D开发者_StackOverflow中文版o I need to do anything special with the application xml configuration?

Thanks in advance!

Use application.xml for standard j2ee configuration, sun-application.xml is the vendor specific descriptor. You'll find that other containers have vendor specific descriptors -- like jboss-application.xml.
