Themes question

[phantom]

Good day,

How can I realise such functionality:

I have 2 themes on my site:
1) Default - with images, CSS etc.
2) Printable - plain text - suitable for printing

I want: for human show Default theme, but for crawles (Google, Yahoo etc.) show by default Printable version. How can I do that? May be some filter?

Basically I have a similar requirement. Not on request.agent but on request.servername.

How can I automagically make the shown skin dependent on facesContext.externalContext.request.serverName without any user interaction?

I'm currently developing a multi-user, multi-domain site with seam - seam is unbelievable. Thanks guys for this great piece of software!

I guess you could install a custom filter using @Filter:
http://docs.jboss.com/seam/2.0.0.B1/reference/en/html/configuration.html#d0e12795

Detect the spider. (Chris has given some clues on how to do that)

Change the theme accordingly, using the themeSelector component. Example:

@In
ThemeSelector themeSelector;
...
themeSelector.selectTheme(...);

HTH

I installed a custom filter (@Filter(within = "org.jboss.seam.web.contextFilter")) and the filter is called as expected.

I can also get and access the ThemeSelector via
Context ctx = new SessionContext(new ServletRequestSessionMap(sreq));
ThemeSelector ts = (ThemeSelector) ctx.get(ThemeSelector.class);

Problem is that I get a NPE when setting a theme. selectTheme throws

java.lang.NullPointerException
 at org.jboss.seam.theme.ThemeSelector.select(ThemeSelector.java:87)

The annotations in my custom filter class are:
@Startup
@Scope(ScopeType.APPLICATION)
@Name("de.dvdb.generic.seam.ThemeFilter")
@Intercept(InterceptionType.NEVER)
@Filter(within = "org.jboss.seam.web.contextFilter")

Is this ok?
