Looks like I misunderstood what themes are doing in CAS. As I understand
it now, the "/WEB-INF/view/jsp/default" directory has nothing to do with
the "default" theme. When you create a new theme, all you have to do is
create a new <theme_name>.properties file inside the /WEB-INF/classes
directory. Then you put name/value pairs in there like "foo=bar". Then
you modify the template at /WEB-INF/view/jsp/mobile/ui/casLoginView.jsp
(for example) and put <spring:theme code="foo"/> in, and this will be
replaced with the word "bar" in the HTML output (you must also create a
"default.properties" file at the same time also with a "foo" defined in
it, or you get an error when someone tries to request a page with the
default theme).
Now, I have two very different styles of web pages depending on the
usage, but most of the changes are separated out into a header file and
a footer file that are currently included via a jsp:directive.include
statement. So if I could do something like <jsp:directive.include
file=<spring:theme code="template_top" /> /> I would be back in
business, but it does not look like you can embed the theme
substitutions in other jsp directives. It also does not look like I can
embed the jsp directive in the .properties files.
I could embed the entire text of the header and footer into the
.properties files, but that's going to be a long and messy bunch of
html, css and javascript.
Does anyone know of a way to do an if/then statement around the value of
a <spring:theme> variable? The differences between the themed pages I
would like to deploy are a lot more complicated than changing a single
CSS include.
Thanks,
Aaron

I'm using CAS 3.3.1 and trying to use two different themes depending
on which website is being passed in as "service". If the user is
coming from our test server, the pages should be rendered using the
"default" theme, but if they come from our "m" server, they should get
a sign-in page that is optimized for viewing on a smartphone.
So far, I have
copied the WEB-INF/view/jsp/default directory to
WEB-INF/view/jsp/mobile.
made some changes to the
WEB-INF/view/jsp/mobile/ui/casLoginView.jsp so I can tell which theme
I am using.
copied the WEB-INF/classes/default_views.properties file to
WEB-INF/classes/mobile.properties and
WEB-INF/classes/mobile_views.properties (the instructions at
https://wiki.jasig.org/display/CASUM/Theme+Control say to "Add another
set of theme properties file, which must be placed to the root of
/WEB-INF/classes folder, name it as theme_name.properties" but there
was no "default.properties" file in that location, only a
"default_views.properties" file, so I created both.
changed the links in these two files to point to the "mobile"
directory instead of the "default" directory.
updated cas-servlet.xml file to add "servicesManager-ref"
<bean id="themeResolver"
class="org.jasig.cas.services.web.ServiceThemeResolver"
p:defaultThemeName="${cas.themeResolver.defaultThemeName}"
p:servicesManager-ref="servicesManager"
p:argumentExtractors-ref="argumentExtractors" />
changed the theme for my "m" server to "mobile" in
deployerConfigContext.xml:
<bean id="serviceRegistryDao"
class="org.jasig.cas.services.InMemoryServiceRegistryDaoImpl">
<property name="registeredServices">
<list>
<bean class="org.jasig.cas.services.RegisteredServiceImpl">
<property name="id" value="0" />
<property name="name" value="m.wvsom.edu" />
<property name="description" value="Allows access via m.wvsom.edu and
uses a non-standard mobile-friendly theme" />
<property name="serviceId" value="http://m.wvsom.edu/**"; />
<property name="evaluationOrder" value="10000001" />
<property name="theme" value="mobile" />
<property name="allowedAttributes">
<list>
<value>UDC_IDENTIFIER</value>
</list>
</property>
</bean>
<bean class="org.jasig.cas.services.RegisteredServiceImpl">
<property name="id" value="1" />
<property name="name" value="WVSOM test" />
<property name="description" value="Allows WVSOM Test Server" />
<property name="serviceId" value="http://test.wvsom.edu/**"; />
<property name="evaluationOrder" value="10000002" />
<property name="allowedAttributes">
<list>
<value>UDC_IDENTIFIER</value>
</list>
</property>
</bean>
Restarted Tomcat, and the default theme continues to come up.
If I edit WEB-INF/cas.properties and change
cas.themeResolver.defaultThemeName=default
cas.viewResolver.basename=default_views
to
cas.themeResolver.defaultThemeName=mobile
cas.viewResolver.basename=mobile_views
then the new mobile theme comes up for everything.
So it seems like the theme is working, but it's either not reading the
theme information from the serviceRegistry, or not getting the
basename from it. Something's not linking up. I also have all the logs
set to DEBUG and the only time the word "mobile" appears in the logs
is when I set mobile to be the default theme and it rendered
correctly. So it does not seem like CAS is even aware that I am trying
to get it to display an alternate theme.
Any help greatly appreciated,
Aaron
