Subject [jira] Created: (CXF-2838) CXFServlet ignores proper ApplicationContext combination loading.

CXFServlet ignores proper ApplicationContext combination loading.

                 Key: CXF-2838
             Project: CXF
          Issue Type: Bug
    Affects Versions: 2.2.8
         Environment: Windows using Tomcat 5.5/Tomcat 6
            Reporter: Carl Holmes

CXFServlet allows you to specify an init-param element specifying the location of an application-context
file to be used in combination with the root application context (loaded via a ContextLoader(Listener/Servlet)
to use to construct beans for web services.  However, this loading process is not done properly.

Say that a user wished to use the root application context, loaded in the ContextLoader(Listener/Servlet)
to provide common functionality (database beans, cache, email services, etc) between different
servlets, but wanted to separate out two different sets of web services (that used these common
beans) and also had another servlet that used these common beans but did not expose web services.
 Normally, that would be done as so:

context loader listener:
   common application context files

Servlet#1(CXF servlet #1)
   only web service beans, including the imports for CXF from its META-INF directories as

Servlet#2(CXF servlet #2, exposing different web services under a different url-pattern than
   only CXF Servlet #2 web service beans, including the imports for CXF from its META_INF
directories as desired

    Gets the root application context and any additional beans it needs

Each servlet would then be mapped on different url-patterns, for example, /services/*, /securedServices/*,
and /.

However, this doesn't work as expected.

I traced this down - and it seems that before the context is refreshed, the bus is read and
a controller is constructed before the servlet gets a chance to even read its initialization
parameter and append these beans to the Root application context to construct a new application
context for it to use.

This isn't a problem for any web application just using an "all beans in the context loader
listener" or "just web services" approach - but it makes the CXFServlet much less useful than
it should be.  The Root application context should be merged with the user-injected specific
application context before any configuration is attempted.
