I am not defining any default action.
I would get the below exception if I set the ActionMapping to null. For some
reason the object doesn't go away, if I set it to null. After setting it to
null using
request.setAttribute("struts.actionMapping", null); I can get it using
getAttribute. The object remains even if I do removeAttribute.

Below is what I see by displaying the
request.getAttribute("struts.actionMapping") after removeAttribute or after
setting it to null.
ActionMapping{name='Login', namespace='/', method='null', extension='action',
params={}, result=null}
In StrutsPrepareAndExecuteFilter below is the line that gets the action
mapping, since the forceLookup is set to true the PrepareOperations class might
be creating it again.
ActionMapping mapping = prepare.findActionMapping(request, response, true);
---------------PrepareOperations-------------------------------
public ActionMapping findActionMapping(HttpServletRequest request,
HttpServletResponse response, boolean forceLookup) {
ActionMapping mapping = (ActionMapping)
request.getAttribute(STRUTS_ACTION_MAPPING_KEY);
if (mapping == null || forceLookup) {
try {
mapping =
dispatcher.getContainer().getInstance(ActionMapper.class).getMapping(request,
dispatcher.getConfigurationManager());
if (mapping != null) {
request.setAttribute(STRUTS_ACTION_MAPPING_KEY, mapping);
}
} catch (Exception ex) {
if (dispatcher.isHandleException() || dispatcher.isDevMode()) {
dispatcher.sendError(request, response,
HttpServletResponse.SC_INTERNAL_SERVER_ERROR, ex);
}
}
}
return mapping;
}
