    - #### getConfigurationLocation

          public String getConfigurationLocation()

      Returns a non-null location of an XML Cayenne configuration, extracted from the filter or servlet configuration parameters.

    - #### createModules

          public Collection<Module> createModules(Module... standardModules)
                                           throws javax.servlet.ServletException

      Creates and returns a collection of modules made of provided standard modules and extra custom modules specified via an optional "extra-modules" init parameter. The value of the parameter is expected to be a comma or space-separated list of class names, with each class implementing `Module` interface. Each custom module must have a no-arg constructor. If a module of this type is already in the modules collection, such module is skipped.
      Throws:
        `javax.servlet.ServletException`

    - #### getParameters

          public Map<String,String> getParameters()

      Returns a map of all init parameters from the underlying FilterConfig or ServletConfig object.

    - #### getOtherParameters

          public Map<String,String> getOtherParameters()

      Returns servlet or filter init parameters, excluding those recognized by WebConfiguration. Namely 'configuration-location' and 'extra-modules' parameters are removed from the returned map.
