hi ,
In our application we are giving permissions to user to select backgroud themes, 4 themes with different 4 .css files, and in the database we are storing the name of the file, after user created his profile and if he wants to see his profile and checked on view profile, then we need to display the theme as he selected when he registered.

How can we display the background theme? actually our jsp is design according to the .css file and each theme's .css file have the same with different colors, images, etc...

we just gathering the name of .css file from the database and we need to display jsp according to the theme.

Could some one help me about this. if possible send a simple code

thanks,
Sumant K

Just use JSP mechanisms to generate the right theme CSS file name in the <link> tag.

E.g.


(Assumes that themeName has been set as a scoped variable at some point.)

The notation I used, ${themeName}, uses the EL (Expression language), available as of JSP 2.0. It is the modern-day equivalent to your old-fashioned scriptlets. If you are using JSP 2.0, or even plan to continue to use JSP in the future, this is a topic you should investigate very very soon.
