Betterway to use global variable in webapplication

Hi All,

I am looking for how to use global variables in my web application.
I have properties file in database and thus whenever required, we retrieve from database. All properties are alomost readonly. Once in a while they get changed in database. Thus server restart is not a problem when any value gets changed.

Inorder to increase the performance, I am planning to use global variables for all properties which will make properties available through out the application and reduce the database interaction.

I have an idea of using Static class to save the values and access these values. This is a webapplication and exists in Websphere server.

Can anybody give me better ways of solving the problem and any flaws of using static class for this purpose.

Thanks & Regards,
Swathi.

You may use Servlet Context initialization parameters for this purpose. They are set up in the web.xml file
 
It is sorta covered in the JavaRanch Style Guide.
