So I'm pretty much sold on migrating from Struts/JSPs to JSF at this
point, with one remaining caveat I've yet to figure out. I've brought
this up before, but haven't found a good solution yet. I think the
easiest way to get what I want is to use struts-faces, but then I can't
get the benefits of Shale... So, I'd like to revisit the base
requirements to see if anyone can see a way to do what I want w/out
Struts Action / struts-faces in the mix...
My base requirement is that everything be directly addressable by a
bookmark-able URL. So, for example, I'd like to have a URL like
http://.../users to be rendered by /users.jsp as a list of users and,
when you click on an entry in the list, you'd get taken to
http://.../users/bob which would be rendered by /userInfo.jsp. For any
X, the URL http://.../users/X would be rendered by /userInfo.jsp, with X
being made available to the JSP (or backing bean) as a request
parameter, request attribute or whatever.
Using struts-faces, I can get what I want by using wild-card action
mappings to map logical URLs to physical JSPs, passing wild-card matched
parts of the request URL on to the view in the action; something like,
roughly:
<action path="/users/*" type="myaction" forward="/user.jsp">
<set-property name="user" value="{1}"/>
I need a way to get the same mapping from logical URLs to actual JSPs
with vanilla JSF / Shale. Sean suggested I could try writing a custom
navigation handler, but that doesn't seem to work since a navigation
handler only gets to influence how from-view-id/from-outcome pairs get
mapped to views.
I tried setting up a front controller servlet that encapsulates the
URL-to-view mapping logic, but that doesn't work because to-view-id in a
navigation-rule is not a context relative path, so my navigation rules
can't route through my controller servlet...
I'm really hoping I can find a way to do this that doesn't involve
deploying Struts + struts-faces as a front controller to Shale ;-) My
requirements can't be *that* weird can they?
