method of implementing a 'login' section in a site
hi,
Thanks a lot for the email guys!! Another question I want to ask. I
want to create a section of my site where I only allow users to use IF
they have logged into my site. Either than using cookies to keep track
if they have logged in or not, what method should I use to keep track
of their status on each page?

Re: method of implementing a 'login' section in a site
Posted by Marco Tedone <mt...@jemos.org>.
Well, what I can tell you what I've done, and then you're free to choose
(what a nice thing freedom...). I authenticated the user against a database;
if the user is authenticated, then I set a session attribute like (type
String): isUserAuthenticated.
Then, I wrote two custom tags (isUserAuthenticated, isNotUserAuthenticated)
which respectively executed the code within a <block></block> depending
whether the session attribute isUser exists (i.e. != null) or not. Then, in
my JSP page, I wrote something like the following:
<isNotUserAuthenticated>
....forward her to the login page
</isNotUserAuthenticated>
<isUserAuthenticated>
<a href="..."></a>
<a href="..."></a>
<a href="..."></a>
</isUserAuthenticated>
I discovered this method is also useful to allow 'Administration'
functionality, so that similarly you may declared <isAdministrator>
<isNotAdministrator>
Hope this will help,
Marco

I would suggest using session tracking to keep track of this state. Place the user in your session and have a small function run in the head of your pages checking for this. If no username is found then call, session.invalidate and redirect the user back to the login screen.

Connector/J or ODBC?
Posted by Christopher Williams <cc...@ntlworld.com>.
Amy,
Always use a native JDBC driver if one is available:
1. The JDBC-ODBC bridge adds another layer of translation and redirection,
slowing down your database operations.
2. The JDBC-ODBC bridge seems kinda flaky. I keep on getting errors staing
that "HRESULT is busy with another operation" when I use the bridge.
Chris.
Re: Connetion between Tomcat & MySQL
Posted by Amy Cheung <ga...@yahoo.com>.
OK. Thanks. It can connects to the database now.
Here is a minor problem. The results I obtained from
the query is a ResultSet, rs. I keyed in this code:
while (rs.next())
{
System.out.print(rs.getString("RoomID");
}
In the Tomcat server, it printed the results that I
wanted. How to incorporate that results into the html
code to show on the web page? I tried but it's give me
error that cannot convert ResultSet into String.
Thanks,
Amy Cheung

Assuming that you aren't using JDBCRealm, then it should be enough to put
the jar file in $TOMCAT_HOME/lib/apps. If you are using JDBCRealm, then
place it in $TOMCAT_HOME/lib/common.
Setting the CLASSPATH is evil ;-).

RE: Connetion between Tomcat & MySQL
Posted by Mike Curwen <gb...@gb-im.com>.
That's just not good advice at all. I don't know where people get the
idea of touching CLASSPATH when they're talking about Tomcat and
web-apps in general.
Drivers should be placed in common/lib or WEB-INF/lib. That's IT.
And mm.mysql.driver?
You mean:
com.mysql.jdbc.Driver
And one last rant, as Chris Williams started to point out... ODBC is a
Microsoft data access abstraction layer.
ODBC = Microsoft Way of doing it
JDBC = Java way of doing it
So you'd only download or use the ODBC driver if you were accessing
MySql from a VB or C# program.

You may want to put the JDBC driver jar file under %TOMCAT_HOME%/common/lib
and try again. This is the location where the classloader loads the classes
which makes available to all Tomcat applications.

I'll assume that you're using Connector /J. Stick the file
mysql-connector-java-x.y.zz-bin.jar (where "x.y.zz" is the version number)
in Tomcat's common/lib directory.
Re: Connetion between Tomcat & MySQL

My apologies (and my tping error), the directory should be "common/lib", not
"lib/common".
Connetion between Tomcat & MySQL

Hi,
I am using Tomcat 3.3.1 and MySQL 4.0 in Window XP.
MySQL engine is running. When I run my jsp, it stated
the error that "import com.mysql.Driver" not found.
Anyone know how to install the driver properly? I read
something about setting the class path. But where to
set? I don't know much about the MSDOS command and
specify the envirnomental variables in Window XP. I
download both the J/Connector & OCBC driver from
MySQL. Where should be the exact location to store?
Thanks,

The way i prefer to do it is use a simple db with the

to check if the user is logged in or not.
one thing i had problems with when i first implemented
this solution is that the cookies are stored in a
browser specific place and you might not be able to
access them easilly. a work round to this is to set
the cookie path yourself from a methid in the API (i
dont have it at the top of my head i will look it up)
and get the cookie reference using the location where

Re: method of implementing a 'login' section in a site
Posted by Billy Kantartzis <bi...@vknet.net>.
The way i prefer to do it is use a simple db with the
user atributes (userid , password , etc), use cookies
to check if the user is logged in or not.
one thing i had problems with when i first implemented
this solution is that the cookies are stored in a
browser specific place and you might not be able to
access them easilly. a work round to this is to set
the cookie path yourself from a methid in the API (i
dont have it at the top of my head i will look it up)
and get the cookie reference using the location where
the cookie is stored
