The AssemblerTools.defaultContentItemToRendererPath property specifies the default component that should be used to map a response ContentItem to its correct renderer. Having this default ensures that the same mapping component is used across all web sites:

# Our default service for mapping from a ContentItem to the path of
# its corresponding JSP rendering page
defaultContentItemToRendererPath=cartridge/renderer/ContentItemToRendererPath

You can override this setting on a web application-specific basis by specifying a context-param in your application’s web.xml file. The name of the parameter must be contentItemToRendererPath and the value must specify the Nucleus path of the mapping component you want to use:

  <context-param>
    <param-name>contentItemToRendererPath</param-name>
    <param-value>Nucleus-path-to-mapper</param-value>
  </context-param>
