I may be wrong, but I remember encountering an issue with my maven overlay, which defined an additional servlet that to fix I had to explicitly load propertyFileConfigurer.xml even though all the other beans defined in deployerConfigContext were present.
I believe it is related to how bean contexts are layered on top of each other for servlets and how PropertyPlaceholderConfigurer works. PropertyPlaceholderConfigurer works via the BeanFactoryPostProcessor interface, which only applies to the bean context it is directly loaded in and not to any children context that inherit from the parent context. This matters with servlets because there is a global context that the majority of the cas beans are loaded in, and then there is the servlet context which inherits from the global context and defines some additional local beans. So, merging propertyFileConfigurer.xml into deployerConfigContext.xml would mean 1 of 2 things, 1. cas-servlet.xml would have to explicitly load deployerConfigContext even though all the beans were already loaded in the global scope. or 2. cas-servlet.xml could no longer use property placeholders (There are currently several placeholders in cas-servlet.xml) -Daniel On Jan 11, 2012, at 4:45 PM, Scott Battaglia wrote: On Wed, Jan 11, 2012 at 4:39 PM, Andrew Petro <ape...@unicon.net<mailto:ape...@unicon.net>> wrote: Deliberately forking this thread, since I don't want this detail to distract from discussion about the general approach. Bill, I have a (possibly irrational) fear of this bit: > * Move the propertyFileConfigurer configuration block into > deployerConfigContext.xml (minimize config files) I vaguely remember having found it handy that the property file configurer *isn't* in deployerConfigContext.xml. I'll either figure out where I tripped over this and report back, or please ignore my hand wringing with my apologies for the thrash. I don't know if it really breaks anything so much as you want to keep things in there that you really expect deployers to modify (because otherwise if you have to change/adjust it, people have to then do it in their file which they are pretty much guaranteed to have changed).
