Subject RE: Is it possible: get DB fields with a taglib, process with a form bean
Date Thu, 17 Jul 2003 02:05:19 GMT

Thank you

I am using struts, and am relatively new to java, I have never dealt with a
map??, and don't know what JSTL is, but I am reading up on it now. If there
is a resource that shows something like this it would be appreciated.

i'm guessing that you are using Struts...so, why don't you just get those
fields out of the database in an Action class and set them as a request
attribute? maybe you could store them in a Map with constants in your JSP
as your keys and then use JSTL to retreive those values? If you're doing
that, I would even go one step further and define those constants in your
application resources file...But try this:

<html:select value="<c:out
value="requestScope.selectMap['MY_FIELD_NAME']"/>"> 

I know this has been a big discussion of late, but I would stay away from
a tag library that grabs stuff out of a database. If you're using Struts,
why would you want to give up the benefits of the MVC2 pattern by adding
tags that do logic to your view?
