RE: [Q] Accessing struts-tiles attribute in a bean?

2003-03-17 Thread Hue Holleran

Ted (Husted) has created a 'tiles for Velocity'. He did qualify that by
saying it was not as fully-featured as Cedric's - as I think original tiles
took a good while to develop - but Ted's was designed in the shower (or
bath - I don't recall) and then developed quickly afterwards.

However, that said - I'd be really interested in taking a look at that
code - maybe his new book could be 'Struts on Speed' (not the author as he'd
never get on those stilts - but Struts with Velocity).

Ted - what's the chance of posting your views (or pointing us to a link) on
how you're using Velocity with Struts. I did have another look at Velocity
after your presentation but I still don't think I can do without tiles -
even with the promise of 'cross platform' Velocity.NET/NVelocity it doesn't
do it for me?

 be more to discover with tiles and so many ways it can be extended to suit

 Subject: [Q] Accessing struts-tiles attribute in a bean?


 James and Dan turned me on to tiles. I love them - as I love any tool that
 simplifies what I was already doing via brute force. :-)

 I feel I'm on the verge of a new level of understanding, but sadly,
haven't
 quite crossed over.

 In my tiles structure, I want to have my pages get their titles from the
 application resource.

 So I dutifully created a titleKey attribute in my tile-description.xml,
like
 so:
 definition name=StandardLayout path=/Jsps/Templates/TemplateMain.jsp
   put name=titleKey value=some.resource.key/
   put name=header value=/Jsps/Tiles/TileHeader.jsp/
   put name=content value=/Jsps/Tiles/TileWelcome.jsp/
   put name=menu value=/Jsps/Tiles/TileMenu.jsp/
 /definition

 In my TemplateMain.jsp, I want to take that titleKey and look up the
proper
 title string from my application resource file.

 But I can't figure out how to access the value of the titleKey attribute
 into the key field of the bean:message tag.

 Is this possible?

 One day a light will go on in my head, and I won't feel so confused by all
 this. :-)

Re: Strutsaction on different WebApps

2003-03-17 Thread Kjellaug Johansen

Maybe I didn't explain my problem good enough...

The name of my application is WebApp. This name is similar for both the
production server and the test server. The servername (if you understand
what I mean by that term) on the testserver is www.mycomp.com/test, and the
servername on the productionserver is www.mycomp.com.

You suggested to deploy the test-application under a different name (i.e.
test-WebApp), but the problem is that I can't have the same servername for
the test- and production server. See? It's ok to have different
application-names, but the servername have to be different, because there
are in fact two different servers on two different machines.

It seems like Struts thinks the servername is www.mycomp.com even if I'm
working on the testserver with the servername www.mycomp.com/test. Why is
this a problem in Struts?

I hope this explanation was clear to you... I appreciate any response on
this problem :-)

Subject: Re: Strutsaction on different WebApps


 Sorry that no one helped you, but let's take this back to the list.

 How are you planning to do this?
 What is the name of your application?  test or WebApp

 Are you familiar with Request Path Elements?
 You should read the servlet spec (section 4.4).  That will give you a good
 understanding of why the approach you've described is giving the results
you
 didn't expect.

 My only suggestion to you is to deploy your WebApp under a different name
 rather that trying to nest it under some directory.

 I wouldn't recommend running your test server as your production box, but
if
 you have no choice, try naming your test application as test-WebApp and
 deploy it right beside WebApp.

 That would give you this:
 www.mycomp.com/WebApp
 www.mycomp.com/test-WebApp

 ...I think you'll start seeing the behavior you expect.

 Subject: Strutsaction on different WebApps


 I've posted this on struts-user mail archive, but there haven't been any
 response, so I hope you could help me! I hope you have some time to look
at
 my problem. Thanks! :-)

 I have two servers running webapps, one for production:
 www.mycomp.com/WebApp and one for testing: www.mycomp.com/test/WebApp

 When I work on the production server there are no problems, but when I
work
 on the test-server and try to call a Struts-action (i.e.
 www.mycomp.com/test/WebApp/user/saveUser.do), I'm getting redirected to
the
 production-server. The 'test' part in the URL for the test-server is
ignored
 and I'm getting redirected to www.mycomp.com/WebApp/user/saveUser.do.

 The struts-config on the testserver looks like this:
 action path=/user/saveUser
 type=com.mycomp.web.user.SaveUserAction
 name=user
 scope=request
 input=/jsp/user/editUser.jsp
  /action

 The action call in the jsp file on the testserver looks like this:
 ... action = /user/saveUser.do

 My questions are:
 Doesn't Struts manage an extra level (test) between the serverroot
 (www.mycomp.com) and the webapp name (WebApp)? Are there any
config-settings
 I can do to solve this?

[Q] Scaffolding question in relation to multiple possible forwards

2003-03-17 Thread Ted Husted

There's a dispatch method on the ProcessResult that you can use for 
that. In this case, you would set it to age70. The ProcessAction woudl 
then look for an age70 ActionForward.

The idea is that the concept of success, failure, age70, and any 
other of these tokens belongs to the business layer, and Struts inherits 
them.

This is a great example since the idea of doing one thing or another 
because of an arbitrary age group is what business logic is all about. 
The business logic says age70. The presentation logic maps that to 
/pages/age70.jsp.

In other words, the business controller (Process*) says jump and the 
presentation controller (Struts) responds with /how/high.jsp.

HTH, Ted.

I should probably do a how-to, but here's a clip from a Tiles Support
thread on the Velocity User list:

Mark de Reeper wrote:

/tr
tr
td#if($footer)#parse($footer)#end/td
/tr
/table
#parse(/WEB-INF/templates/vm/htmlfooter.vm)
Then define a template to set the layout and the various bits, this is
what is loaded as the main template to parse:

#set ($body = /WEB-INF/templates/vm/templatebody.vm)
#set ($footer = /WEB-INF/templates/vm/templatefooter.vm)
#set ($header = /WEB-INF/templates/vm/templateheader.vm)
#parse(/WEB-INF/templates/layouts/layoutHBF.vm)
Ted Husted wrote:
This is just how the original Struts Template library worked. (Great
minds and all that.) You defined a second file to administer the
template. This works well enough but it tends to generate a lot of
meta-templates that are just used to call other templates.

As Slavik pointed out, Tiles extended the template library so that you
could express the meta-templates in XML. Instead of forwarding to the
glockenspiel.vm template, you can foward to make a reference to say
/vm/Glockenspiel and Struts will automatically look for a
vmGlockenspiel element, do whatever sets you need, and the forward to
the layout.

A very neat aspect of Tiles, that we need to adopt for the other Struts
configurations, is that one element can extend another. So if you just
needed to replace the title on a page, you can extend one element and
just override that one set. This makes a *huge* difference in
maintenance when you pass the thirty page mark.

Until one of us gets around to writing a Tiles tool, I've prototyped
what you can do in the Struts config. I've a ViewAction that does the
setting. You create the variables to set as Struts ActionForwards and
pass their names to ViewAction as ActionMapping parameter. So I have
something like this to describe a page:

action path=/vm/main/permit/View
type=us_ok_deq_wqdata.http.ViewAction
validate=false
name=permit_select_id
parameter=vmTitle,vmChoice,vmMenu,vmBody,vmAction,vmButtonBar
forward name=vmTitle path=Permit Detail /
forward name=vmChoice path=View /
forward name=vmMenu path=/cpu/menu/main.vm /
forward name=vmBody path=/cpu/permit/view.vm /
forward name=vmAction redirect=false path=/Main /
forward name=vmButtonBar path=/cpu/permit/viewMain.vm /
/action
To render the same page but with a different button bar, I'd just
change that forward to include some other template instead.

Besides URI's for parse statements, you can also pass any variable you
need to create. For example, vmChoice tells the menu which item we are
on, so it can dim that one (and leave the rest linked).

While we can't extend struts-config elements (yet), the ActionForwards
do have a local and global scope. So you can do things like create a
global default forward and let that pass through when it doesn't need to
be changed. This is done for the Layout. There's a default vmLayout
forward which can be overridden by an element if you need to use a
different layout.

This works fine inside of Struts and will work even better when we get
the Struts config to support extended elements like the Tiles config.
But, it seems to me that it's something that could also be done outside
of Struts and made available to anyone using Velocity.

For programmers, this sort of thing makes the templates feel
object-orientated. You can define a base element and then extend it to
say what changes. For designers, they can use Velocity templates seem
more like fill-in-the-blank Dreamweaver templates. A GUI, like Struts
Console, can even save you from mucking about with XML.
