Session Question

[Su...@epamail.epa.gov]

I am currently writing a pretty complex data entry HTML page for an
application.  The HTML has 7 different frames where data is input, one
represents the master table and the others detail tables.  I am trying to
come up with a way to keep all of the data entered into each frame for
updating the database (I want to update all the records in one
transaction).  There some obvious ways of doing this as with invisible
fields on the master frame, and URL rewriting (cookies are out in this
case) but I have also been looking into using the Session object.  I know
the object is used for shopping carts on commercial web sites but would it
be a good to use it to keep all the input values for various input forms?
There will be from 40 - 50 items of data stored in the session object and a
user will only be able to one form at a time?

Thanks in advance

Yes, sessions are provided for this kind of thing. Note that Tomcat uses
cookies to maintain the session if it can. It will use URL rewriting if
cookies are disabled but you may have to amend your pages to support that.

It may be worth looking at a web application framework such as Jakarta
Struts that can run within Tomcat and help with some of this.

web-based version of mailing list?

Hi

This is probably a silly question, but ever since I subscribed to tomcat-user
I've been bombarded with emails (200 a day). Is there a web-based searchable
version of this forum available? How is everyone else coping? 
The best I can do is filter tomcat-user posts to a special mail folder.

Cheers

W2K + isapi_redirect.dll + Tomcat, 2-byte chars

[derhong <de...@sinomovie.com>]

My server config is as follow:
IIS	port 80
Tomcat	8080
ajp12	8007
and the request is sent from IIS to Tomcat via isapi_redirect.dll.

The problem is that when I have Chinese characters in my query string the params got lost if I make the request to port 80. It works fine if I make the request to port 8080 directly.

I would guess that's something wrong with ajp12 or isapi_redirect.dll. Is it a configuration issue? or is is the implementation? What's the solution?

Thanks.

The session is usually used to persist objects between
tranactions with the client (browser).
If you are gathering several input fields to write to
the database towards the end of the "session" then
using the session is the way to go.

Or, you could use Java Script to gather all of the
input fields from the frames you mentioned into hidden
fields of the form being submitted and write to the
database when the form is submitted.
