Re: Servlet call from JSP/HTML - Need help
I am looking to do just what you have proposed. How do you preload the action.

RE: Servlet call from JSP/HTML - Need help
Nathan, What I am going to do is A) Create a servlet that does nothing but queries the data (I know which all tables are going to be used for Query), and load these data as application scoped. This will be set in the web.xml as load on startup. B) Now in my JSP, I just build up the select list using core:foreach (I use mix of JSTL and struts taglib) on the application scoped variable . C) Wherever I need a dynamic loading, I am going to show only one select in one page, so that when the user does a continue on the previous page, the action is forwarded to Action wherein I query the data and load it as request scoped or session scoped and then forward to this JSP. If you don't want the servlet in the as a load on startup, then you can create an Action component and move the same logic to this Action Component and forward to this Action component directly from the index.jsp (to get into struts framework) and then from there forward to your Login screen or whatever is your entry screen. Hope I am making sense :). -Original Message- From: Nathan Maves [mailto:[EMAIL PROTECTED] Sent: Thursday, October 23, 2003 10:00 AM To: Struts Users Mailing List Subject: Re: Servlet call from JSP/HTML - Need help I am looking to do just what you have proposed.

RE: Servlet call from JSP/HTML - Need help
Well, if the values to show dont need to be dynamically loaded based on other user input on that page then of course best practice is to load them in the action before forwarding to the view. (If the values dont change at all while the app is running then it would be even more efficient to load them into servlet context with a plugin at startup) We thought you needed to do some really complex db lookup based on other fields in the same form that was too dynamic to effectively preload results for. -Original Message- From: Shishir K.

RE: Servlet call from JSP/HTML - Need help
I like the idea of loading most of the selects type as servlet context. There are a couple of select types that may change when the user is in the web form. I can load them as session scope. However, If I had to do the dynamic stuff, how would I implement it. Are there ay code snippets that could help ?
