Re: Multiple struts-config.xml files?
I asked a similar question re potential problems with multiple action servlet instances(no reply). I think the issues may have something to do with the actionservlet resources but I'm not sure and would be **very** interested in finding out as I'm using this approach using struts 1.0.

Re: Multiple struts-config.xml files?
The Struts 1.0 ActionServlet stores a number of elements in Application scope. // Publish our internal collections as necessary getServletContext().setAttribute(Action.FORM_BEANS_KEY, formBeans); getServletContext().setAttribute(Action.FORWARDS_KEY, forwards); getServletContext().setAttribute(Action.MAPPINGS_KEY, mappings); So, it's really not really threading issues (mispoke), but the last ActionServlet would win when it came to the Application scope elements. The custom tag extensions look to these to retrieving the ActionForwards and what not. Check for these statics in utils.RequestUtils, and you will see what I mean. Of course, if you are not using the custom tags, then it may not matter. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Java Web Development with Struts. -- Tel +1 585 737-3463. -- Web http://www.husted.com/struts/ Struts Newsgroup (@Basebeans.com) wrote: Subject: Re: Multiple struts-config.xml files?

RE: Multiple struts-config.xml files?
For the record, to create multiple ActionServlets, I just extended ActionServlet with an empty class body - basically creating an identical servlet with a different name, for each role. This is working fine with each ActionServlet reading a different struts-config file. Could there be some other problem with resources? -Original Message- From: Struts Newsgroup [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 14, 2002 3:55 AM To: [EMAIL PROTECTED] Subject: Re: Multiple struts-config.xml files?

Re: Multiple struts-config.xml files?
I just had one ActionServlet, and for each action defined in it's struts-config.xml, there is a separate forward defined per role (prefixed by role name). role1_success role2_success etc. All forward name strings (e.g. success) get intercepted essentially by a super class Action and then the user's role is added to the forward name. The actual ActionForward is then looked up in the action mapping and returned to the Struts ActionServlet.

Re: Multiple struts-config.xml files?
Struts 1.0 isn't designed to permit multiple ActionServlets. Unless
you've made some alterations, there may be threading problems.
Struts 1.1 does speak to the issues you raise, but we are all still
getting our heads around it, and trying to put some documentation
together.
I was also just thinking about trying something like what Nick
describes, but in the context of localization or browserization, but
it could work the same as roles. But I'm thinking along the lines of
getting the ActionMapping and ActionForwards do the work.
What I'm thinking about is using an ActionMapping subclass as an
ActionForward factory. When calling findMapping, you could also pass the
request. It would then return a new ActionForward, that would know how
to amend the path according to something in the request or session. Like
the locale, or maybe a role object.
It would then work like Nick described. Instead of just going to
/pages/some.jsp, it could go to /pages/fr/some.jsp or pages/zh/some.jsp.
Or in your case /pages/manager/some.jsp or /pages/clerk/some.jsp. If
some paths could be changed, and others couldn't, there might be a
marker in the path, like /pages/{0}some.jsp, for the ones that could be
merged.
Still at the thinking stage though.
