Interesting, I hadn't thought of that. However a problem I see here with
this approach is that it implies that there would be different versions
or a different mapping for every view whereas in reality, if a page
looks / works fine on say iphone, htc, windows mobile but doesn't on an
old blackberry then I want to be able to create a tweaked page for one
device, but all others would use the same page and mapping.

How about using different packages/namespaces for the views?
<package name="package_blackberry" namespace="/bb">
<action name="login" class="mypackage.LoginAction">
<result name="success">/bb/index.jsp</result>
</action>
</package>
<package name="package_winmob" namespace="/wm">
<action name="login" class="mypackage.LoginAction">
<result name="success">/wm/index.jsp</result>
</action>
</package>

Hi,
I am wanting to implement a site such that some actions may have a different
mapping depending upon the device used (e.g. regular browser / mobile device
etc.) but what I don't want to do is have to litter my actions with this
type of logic. It could be at the result mapping level (i.e. in struts.xml)
such that say a result of success would map to a jsp of somePage.jsp for
regular browsers and somePageMobile.jsp for a mobile device (there will be
more complications to this as I'd like to be able to have fine grained
control based on the user agent so there may be many versions of a jsp such
as somePageWinMobile6_5_htc.jsp).
There are couple of ways I can think of to do this, but they're ugly:
- JSP level logic to render the page differently - dont want it, I'd rather
individual jsp's for each supported device (or family) as this allows
developers who are working on targeting a site to a specific device to
concentrate on that device.
- Tiles template level logic - again not ideal as I would like to be able to
use specific templates for device types.
Better but not perfect would be some sort of post action result modifying
interceptor such that in the struts.xml I could define a number of different
result mappings such as success, success_winmob, success_blackberry_storm
and have the result string that has been returned from the action (success)
modified by some sort of interceptor (e.g. appending the suffix prior to
struts mapping it off to a view) - the filter itself could be configured as
to whether or not to alter result strings based on the action and the user
device. - Is it possible to modify the result string post action but prior
to struts resolving the mapping? And if so would I have access to the the
name of the action?
Any suggestions here are greatly appreciated!
Web technologies being used are Struts2, Tiles2 and JSP.
Regards,
Marcus
