Re: [struts-menu] how to use URL rewriting ?
I wrote a MenuDispalyer that can be configured in a properties file. It will not solve your problem but it show how you can write your own MenuDisplayer to add replacement variable you need. It will require you to retrieve the session id from the pageContext and then pass it as a parameter for message resource replacement. If you are interested by my code look at the patch section of the sourceforge account of Struts-Menu where I posted it as RecursiveMenuDisplayer. Then look at RecusrsiveMenuDisplayer.getDisplayString(String key, String content, MenuComponent menu) to see how the variable are prepared. Malik.

Re: Multiple struts-config files without Modules
Tuesday, February 04, 2003 8:12 PM , Ted Husted [EMAIL PROTECTED] a écrit : Is it dumb ? Or may it be an advance of the feature promised in 1.2 that will allow inheritence of configs ? Just to be precise, no one is able to make any promises about any features for any possible future release. No need to be so defensive. My english (and myself) is not very accurate, so I correct : of the feature that some rumors whispered that will maybe allow a form of ineritence of configs in a forward version. At this point, 1.2 may just be the patches for minor enhancements that came in while 1.1 was in never-ending beta, along with the Commons Resources migration. I'd like to see the same type of element inheritance in all the configs that we have in the tiles-config, but someone will have to create and commit the patches for this before it gets slated for a release. I agree with the tiles-like solution. It's efficent and simple. There's no need to make a complete object-c++-like type of ineritence. Template, default values, and overloading is enought. But if I can give my opinion, one interest of inheritence in config files is not only the factorization of declarations (that multiple files yet allow) but also the ability for third party to deliver some ready-to-use applications that the final user will just need to customise (if he want to) by overloading some configuration such as data sources for exemple. (actualy maybe a final feature will be usefull to). Malik. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I started using this for organizational purposes mainly, but I am curious if there are any pitfalls that I should be aware of. Any comments are appreciated. If the contentes of your three files are constructed correctly (i.e. you don't try to declare the same action path more than once, for example), then order does not matter at all -- Struts simply processes all of the files at initialization time. The ability to split is simply for the convenience of the application developer (particularly when you might have different subteams responsible for different parts of a single large single-module app).

I don't understand your response. The code I propose below does in
fact use delegation to factorize the functions.
I'm ok with that.
However, by
utilizing an interface, all code that works with MyAction and
MyDispatchAction objects now has a contract that says that both
objects support the CommonFunction methods. Thus that code can deal
with both objects as CommonFunction objects if it wants to.
I was just pointing out is that probably no client code will use the
CommonFunction interface of MyAction and the MyDispatchAction but themselve
so it's maybe not usefull to implement it. And even if a client need
CommonFunction why should they use a MyAction or MyDispatchAction instance
rather than a CommonFunctionImpl instance ?
If there is a need for a contract here, it's also a contract for a behavior
not just for an interface. When you multi-inherite you take the interface
and the behavior of each parent classes. It's not garanteed here for the
clients of CommonFunction interface that they will have the behavior of
CommonFounctionImpl. If you implement a function of CommonFonction another
way than delgating to CommonFunctionImpl nothing will warn you about. So it
is not quite like if you extends Action and CommonFunctionImpl.
Java does not support multiple inhereteance and so there is *no way* to
replace it exactly. This said, and Ashish warned, your code is very clean, I
have nothing about that.
This is
what I understood that Ashish wanted to do. IOW, what's your beef?
--Cory
[EMAIL PROTECTED] 01/31/03 09:17AM
I don't agree with the interface solution. As the name sugest
CommonFunction
seems to be only factorization of code and not a real type. MyAction
and
MyDispatchAction will never be called from outside as some
'CommonFunction'.
Interfaces are meant to be externals contracts not a way to replace
inheritance.
IMHO when you want to factorize functions in sevral Classes of
different
types you only need to delegate. But maybe I missunderstood what
Ashish

Re: JSP's under WEB-INF and Struts modules
Hi, I've got the same problem. The solution is to use forwardPattern and inputForward options to have complex, pattern based, repalcement of the uri : http://jakarta.apache.org/struts/userGuide/configuration.html#controller_con fig But after few tests and a look at the source code of struts b3 and nigthly builds, it seems to me that there is two kinds of uri replacement. For forwards and input the RequestProcessor use the given forwardPattern to replace uri. But for the forward attribute of actions a trivial appending of the name of the module is performed. So all path are not replaced the same way witch gives me unresolvable errors. So I posted a bug report here : http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16603 As you are, I'm still waiting for the witness of a sucessfull configuration of a multi-modules app with pages and tiles under WEB-INF.

Friday, January 31, 2003 9:18 PM , Moyer, Alan L [EMAIL PROTECTED] a écrit : I just read Chuck Cavaness' article Jakarta Struts: Seven Lessons from the Trenches In it he recommends putting the JSP pages underneath WEB-INF. In the article he shows how to write an action as action path=/logoff type=org.apache.struts.webapp.example.LogoffAction forward name=success path=/WEB-INF/jsp/index.jsp/ /action However, if the application uses multiple Struts modules, I don't see how this would work. If the application is foo and the module is bar, wouldn't the address of the JSP be expanded to ../foo/bar/WEB-INF/jsp/index.jsp but WEB-INF isn't under bar, so this won't work. If, however, index.jsp is in directory foo/bar/jsp/ above WEB-INF then path=/jsp/index.jsp expands to ../foo/bar/jsp/index.jsp which works. Any idea how to make the URL expansion work when the JSP's are under WEB-INF.

Modularization
Hi to all, Does somebody finaly have been able to set à modularized app with pages, tiles and stuf in another place than the root of the webApp ? For exemple under the /WEB-INF/ folder ? I yes how does it use forwardPattern and pagePattern ? Witch paths does he set contexte-relative and witch module-relative ? Can he give us his config files and a vue of is folders tree ? Because I think module-shifting of URI is bugged when one not place files right under /TheWebApp/ or at leat it's fuzzy. I found it is not the same behaviour for all given paths : action.forward, action.input, forward.path, ForwardAction.parameter, tiles, etc. Malik. -- N'envoyez jamais à tout votre carnet les mails qui vous disent de le faire.

The siglton does'nt need the *Class* to be static but the *instance* attribute. So as soon as you do .getInstance(), the instance attribute of TemplateCache is affected to a new TemplatesCache and will stay as long as the app live if you don't don't re-affect 'instance' to another object (but you must not). By the way and to come back to the true subject of the list , I coded such a cache for xslt Templates, but I don't make it a singleton as I want severals caches for each struts module context. So the unicity of each instance is managed via a hashtable referenced in the ServletContext by a key like TemplatesCaches.

You could create a CommonFunctionsFactory, with a
method:
CommonFunctions getCommonFunctionsByClass(Class)
Your action could pass itself to this call to
retrieve a CommonFunctions
implementation, determined by the Factory, which
could look up in a
properties file which implementation to create for
the specified class. You
wouldn't really need to have your action implement

Make your
