Re: multiple modules cannot retrieve mapping not fun!
Use this /author/loginAuthor.do in html-el:form HTH Manish Singla Matt Pease wrote: Hi all -- I'm trying to move to struts 1.1 multiple application modules am getting a very frustrating error that I can't seem to move around. I've searched the archives haven't found a solution. Bummer! When I try to access a very simple JSP (/author/login.jsp) with a html:form, Struts gives an error saying Cannot retrieve mapping for action /loginAuthor. What is strange though is that I can go to /author/loginAuthor.do struts finds the mapping then. It seems like the login.jsp page doesn't realize that it is in the author sub-application. How do I make the JSP know which sub-app it is part of?

What are the advantages of having multiple struts-config modules defined in web.xml vs comma separated struts-config.xml from design point of view. I am ok with slight overhead of multiple struts-config file (in web.xml approach). Again, what design problem multiple struts-config problem is solving.

RE: Multiple modules - Please help
It wouldn't be (easily) possible to change ForwardAction to be configurable
between context and module relative because the ActionMapping only has one
parameter which is already being used to provide the path.
A couple of options would be to create a second version of ForwardAction
(ModuleForwardAction ?) that returns a module relative ActionForward, or to
create a simple action that returns an ActionForward which is configured in
struts-config with a well-known name (success, in my example).
I prefer the latter approach because it is more flexible and uses the
standard method of configuring the ActionForward via struts-config. You'd
have to create your own for now, but I hope to add this as a standard
action.
The action (SuccessAction):
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
return mapping.findForward(success);
}
struts-config.xml:
!-- Module relative mapping --
action path=/showEdit
type=com.ninsky.struts.actions.SuccessAction
forward name=success path=/edit.jsp/
/action
-or-
!-- Context relative mapping --
action path=/showEdit
type=com.ninsky.struts.actions.SuccessAction
forward name=success path=/admin/edit.jsp contextRelative=true/
/action

Dear Steve,
Thanks for finding the problem in the configuration file. I had
not realized it. ** sorry for the typo in bug report **
So, now I have an enhancement request.. :)
Would it be possible to enhance ForwardAction so that it also
requires a MODULE relative path ?
It would be then very intuitive and convenient.
Also, splitting into modules will be easier as you simply have to
chop off the module path globally. Changing module names will be
even easier.
If you think the above is ok and it doesnt conflict with the current
implementation, I shall re-open the bug as an enhancement request.
Please let me know,
Thanks a bunch,
Ajay

RE: Subject RE: Multiple modules - Please help
Ajay, I've closed this bug. It seems to be a configuration problem... I'm assuming that your add.jsp and edit.jsp files are in the /admin directory. The problem is with your configuration. ForwardAction requires a CONTEXT relative path which, in this case would be: action path=/showEdit type=org.apache.struts.actions.ForwardAction parameter=/admin/edit.jsp /action (Note also, you had your parameter in a separate tag, but it should be an attribute of the action tag. Not sure if that's what you actually had in your source or it's just a typo in the bug report, but it wouldn't help!) The reason it worked when you used your own custom action is that by default ActionFoward paths are MODULE relative, so your configuration entry /edit.jsp would be translated by the RequestProcessor to a context relative path of /admin/edit.jsp ... if you still have problems after this, please post back to the user list.
