Rafael, do you remember, that it is not a good Struts practice to call jsp directly? It is better to call action, which would forward to jsp. About storing data somewhere in Struts instead of using session or application scope directly. When I started to use Struts, I also wanted to use Struts objects exclusively. I had some sort of fear of using non-Struts structures :) But in reality Struts is a very thin layer on top of JSP/servlets. Struts request processor is a servlet, and each action form that you declare in struts-config.xml is a Java bean, stored in appropriate scope. Only instead of initializing these beans manually Struts does it for you. So, instead of storing stuff in action or in an action form you can store it directly in the session or in application context. Also, read about "servlet lifecycle" and see, maybe you better create a helper servlet and initialize global data when servlet starts. You can set the order in which servlets are initialized. Tax data like yours is better be stored in application scope, not in session scope. Session scope belongs to a client, and you probably do not want to set different tax for every client ;) Michael. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
