Subject RE: Resource Bundle per session
Date Tue, 18 Nov 2008 04:29:36 GMT
Hi Peter,

I also have same kind of requirement and facing issues in this area.

Can you please send me your code for custom AnnotationValidationInterceptor and related files.

Also will it be a optimized way to override the getText method for initializing our resource
bundle? I tried to use my custom TextProvider for this purpose, but struts 2.0 has some issues
in this area. It is fixed in struts2.1 but it's a beta version, so can't go with that. Can
we do this by creating another custom interceptor?

Thanks,
Manish

Subject: RE: Resource Bundle per session

I've implemented something like this using Struts 2.0.12, although it
was quite a bit of work to get running.

I implemented a database-backed TextProvider (DatabaseTextProvider)
which reads resources from the database instead of from resource
bundles. It caches the text so as not to load the database too heavily.
In the getText() methods I use ActionContext.getContext().getSession()
to get the current session, then use session attributes to figure out
which text to display for the current user. Our application is used by
several different companies so we need to customise the text based on
which company the user is logged into.

I then created an extension of ActionSupport which overrides all the
getText() methods, delegating to DatabaseTextProvider which is injected
using Spring. This means that text supplied by DatabaseTextProvider is
available in actions and JSPs, and will be used by any struts tags.

This worked OK but Struts does not make it easy to override TextProvider
in the validation interceptor. To get this working I had to extend
DelegatingValidatorContext, AnnotationActionValidatorManager and use
them in a custom AnnotationValidationInterceptor and configure the
interceptor stack to use this instead of the default validation
interceptor. A bit of a kludge (and some copy-and-pasted code) but it
works OK. If you don't need to customise validation text then you won't
need to do this.

Hope this helps.

Peter

Thanx for the prompt Nuwan. However, this will cause overlapping in
users
different resource bundles. As LocalizedTextUtils store the default
bundle
list in a static map in static member variable.

Instead of this ServletContextListener  you can  have a
 HttpSessionListener, just a suggestion, i haven't tried it.

Thanks,
