[Springframework-developer] themes

[JP P. <jp....@ti...>]

Hi Everybody,

As I have the need for using themes, I made the job.
But I don't know about your feeling on this. As many central files had
to be touched, despite of the fact than no test was broken and a "real"
test run well, I committed it in a new branch "theme" for now.

The javadoc and the test suite are to be made. I'm waiting on reactions
to know if I can make the change in the main repository and finish the
doc and testsuite.

For users that will not handle themes nothing new is required in the
configuration. This implementation is mainly a map (themes) of new
messages sources and the user is able to choose the theme to use for
display. Changing the theme is close to the locale handling and using a
theme is close to the message source handling, but depending on the
chose theme. Accessing to the themes messages is done via a new tag
"theme" which runs like the "message" tag. For be able to change theme,
only a ThemeResolver bean (provided) has to be added (cookies or
session).

What is preferably to put in theme's resources instead of the standard
message source?
Obviously, stylesheets and images paths which can vary both on locale
and on theme.

I have changed the pagedlist demo to demonstrate also the theme
handling.
As I have some trouble to access on logged ftp at the official site, the
demo is visible at http://tech.jppawlak.info/spring/samples/pagedlist/
The war file (renamed as zip) with sources is available at
http://tech.jppawlak.info/spring/pagedlist.zip
The modified spring library is on the repository under "theme" branch.

The user can toggle between "theme" and "metal" themes.
Note: a little bug with JSTL handling makes some links don't work as
long as the session-id is added on the url. For testing, the best is to
change locale first.
I will fix this starting next week.

For each theme, the css file is defined in the no-localized file and the
images in localized since they depend on locale.

The modified and added (with +) files are:
context/ApplicationContext
+ context/NestingThemeSource
+ context/ThemeSource
context/support/AbstractApplicationContext
+ context/support/ResourceBundleThemeSource
web/servlet/DispatcherServlet
+ web/servlet/ThemeResolver
web/servlet/support/RequestContextUtils
+ web/servlet/theme/CookieThemeResolver
+ web/servlet/theme/FixedThemeResolver
+ web/servlet/theme/SessionThemeResolver
web/tags/i21.tld
web/tags/TagInWebApplicationContext
+ web/tags/ThemeTag
