also whats going to happen if you have a textfield that its value is "03/17/1990"
also I think a CoolUrlTag would make sense to have aswell to write out the Urls just like <ww:url> does now but in the new Cool format

Hi Cameron,
The more I think about the CoolURIServletDispatcher, the more I think it is too much limited. For example I changed the abbreviation syntax from: http://myhost.com/article/paramValue1 to http://myhost.com/article/articleID/paramValue1 instead of http://myhost.com/article/article/paramValue1 .
Why?
Simply because most of the time your action are written that way:
public class LoadArticleAction extends ActionSupport { long articleID;
Article article;
// getter & setter for the above members
// other methods omitted...
}
If you use a parameter named "article" (by using the same parameter name as the one from the action) then you will need to use weird method names in order to retreive the real object linked to this id.
Anyway, I think we should write a custom ServletDispatcher that reads advanced mapping configuration from another xml file (or perhaps extends webwork.xml?).
This file could allow to use the sheme explained above but also deal with URL including dates (like http://myhost.com/2003/10/02).
What do you think about this?
Jérôme.
Selon Cameron Braid <[EMAIL PROTECTED]>:
I have madea patch to the servlet dispatcher to allow for extensability :
the methods that can be overriden are
protected void sendError(HttpServletRequest request, HttpServletResponse response, int code, Exception e) protected Map getParameterMap(HttpServletRequest request) protected Map getSessionMap(HttpServletRequest request) protected Map getApplicationMap() protected String getActionName(HttpServletRequest request) protected String getNameSpace(HttpServletRequest request)
this will allow for the core logic in the service method to be re-used from custom servlet based dispatchers, allowing a custom URL and parameter mapping scheme to be implemented.
Pat / Jason / Others : do we want to include the CoolUriServletDispatcher in the core ?
If so, I will modify it to extend the new ServletDispatcher.

Hum... I should have a closer look at IDEA then :-) Jérôme.

Eclispe can automatically create delegator calls for you,

Cool idea :)
Though, for the implementaion, wouldn't you have been better
to use the
wrapper pattern, rather than dynamic proxies :)
Sure. I thought about it, but it's quite painful: you have to
override so many methods :-(
I'll do it tomorrow and update the attachment in the JIRA issue.

I have created a new issue in JIRA
(http://jira.opensymphony.com/secure/ViewIssue.jspa?key=WW-326
) and submitted a new servlet that extends ServletDispatcher
and provides such a functionality. I also provided a way to shorten even more the URL by assuming that if the first parameter name is not specified then it is supposed to be the name of the action.
This allows to replace the following URL http://myhost.com/article/article/123
with this URL http://myhost.com/article/123.
Any code review welcomed! :-p

Robert Douglass <[EMAIL PROTECTED]>:
I think this is the relevant code, from org.apache.turbine.util.parser.DefaultParameterParser. As I
understand
it, Turbine folks avoid URLs like foo/bar?id=1812 in favor of foo/bar/id/1812. I've never used this, and I can't remember
right off
exactly how the servlet container knows which part is the
path info,
but essentially, they assume that the path info follows
the pattern
name_1/value_1/...name_n/value_n. The advantage is
supposed to be
search-engine friendly URLs from completely dynamic
applications. This
gets touted by the Turbine community as a great feature
(and it may
be). I'd love to have this available, but as you can see
below, it is
easy enough to implement that anyone can do it as soon
as they want
it. I don't really need it at the moment, so I'll let
someone else do
it.

handle URLs? Any
