findActionMapping

public ActionMapping findActionMapping(javax.servlet.http.HttpServletRequest request,
                                       javax.servlet.http.HttpServletResponse response)

Finds and optionally creates an ActionMapping. It first looks in the current request to see if one has already been found, otherwise, it creates it and stores it in the request. No mapping will be created in the case of static resource requests or unidentifiable requests for other servlets, for example.

findActionMapping

public ActionMapping findActionMapping(javax.servlet.http.HttpServletRequest request,
                                       javax.servlet.http.HttpServletResponse response,
                                       boolean forceLookup)

Finds and optionally creates an ActionMapping. if forceLookup is false, it first looks in the current request to see if one has already been found, otherwise, it creates it and stores it in the request. No mapping will be created in the case of static resource requests or unidentifiable requests for other servlets, for example.
