RE: requery db for select lists?

[Paul Bienick]

This would work but if the lists are the same for all users, then it would
be more efficient to store them in the servlet context. I worked on a
application that had many lists of this nature, and I built a simple
LookupManager class which encapsulated a Hashtable of Vectors, keyed by a
string. In my base servlet class (from which all my application servlets
were derived), I instantiated the LookupManager in the init() method, and
stored it in the servlet context. Then, whenever I needed to populate a list
on a JSP, I could simply retrieve the LookupManager from the servlet context
and retrieve the desired list.

If you know in advance that this page needs Database access and the data in
the database will not change between sessions, the best thing is to make a
database access and store the data as a session variable.

Hi,

When a JSP is posted in struts, the entered values get copied to an
ActionForm object so that the JSP can be redisplayed if necessary and the
data survives across the request.

Is this also true for the data in a select list?

On initial creation of the JSP, I will be accessing the database for data
to
populate a select list. But do I have to requery the database if the JSP
needs to be redisplayed?

Thanks in advance.
Andy

RE: Struts Dreamweaver extension

[Paul Bienick]

Hello,

This is great, but I couldn't get any of the .JSP files from the Struts
example app to open without multiple parsing errors. (Dreamweaver/Ultradev
4).

Subject: Struts Dreamweaver extension


Hello,

Some time ago we at Compuware Amsterdam lab announced a project to integrate
the Struts taglibs in MacroMedia Dreamweaver. The project has finished, and
as promised the Dreamweaver extension can be freely downloaded. Goto
http://javacentral.compuware.com and download OptimalJ Dreamweaver
Integration Kit 1.0.9

With this extension, it becomes possible to view and edit JSP files with
Struts tags in Dreamweaver. This extension supports the MVC (or Model2)
paradigm where JSP files provide the view of the application.
It is based on the Struts 1.0 tag libraries. Any comments, etc are
appreciated.

Regards, Marjon Luites and Arjan Kok.
