Re: [Springframework-developer] How to getting at an application context

[Colin S. <col...@ex...>]

At that point, you're stuck with using some sort of singleton or 
quasi-singleton, realistically... (which of course is what the servlet 
context variant is anyways)

You can roll your own, or rely on the singleton implementations of 
BeanFactoryLocator, such as SingletonBeanFactoryLocator or 
ContextSingletonBeanFactoryLocator.
http://www.springframework.org/docs/api/org/springframework/beans/factory/access/SingletonBeanFactoryLocator.html
http://www.springframework.org/docs/api/org/springframework/context/access/ContextSingletonBeanFactoryLocator.html

Note that if you do use these, you will want to probably use a slightly 
modified setup where you use a service layer appcontext, and the web-app 
context is just a child of that, and still loaded normally via the 
context loader listener. This loading is easily achieved with a subclass 
of ContextLoader and ContextLoaderListener, like here:
http://cvs.sourceforge.net/viewcvs.py/springframework/spring/autobuilds/apps/ejbtest/src/java/org/springframework/autobuilds/ejbtest/util/context/ContextLoader.java?view=markup
http://cvs.sourceforge.net/viewcvs.py/springframework/spring/autobuilds/apps/ejbtest/src/java/org/springframework/autobuilds/ejbtest/util/context/ContextLoaderListener.java?view=markup
