RE: session trakking in jsp or in Bean
Thanks I know all about java session.What I mean is implementing session in jsp or in bean which one is advisable Fredrik Rubensson [EMAIL PROTECTED] wrote: Marju wrote: I want to track a session of an input a user enter in my jsp page.The jsp page is using a bean to execute sql queries.That works wel. My question is it advisable to track the session in the jsp page or in the Bean.Which is better I am not sure I follow you here. There is a session object you can get from the request that makes it possible tostore data through several request in the same session. request.getSession().setAttribute(akey, anObject) to set session attributes. request.getSession().getAttribute(akey) to get attributes. If you have users that log in and out you probably should set some user identifying info in the session and a filter to makes sure that the user is logged in for certain requests.

Sebastian Funk [EMAIL PROTECTED] wrote: Hi,
I got the same error a few weeks ago. in my case, the URL was wrong.
you use:
jdbc:mysql://l/AdressBook
Are you sure it's right? Is 'l' really the right host? Did you tried
it with the ip-address?
Best Regards,
Sebastian

I made it Thanks everyone especially jan and Kirthik Byfour Jan Behrens [EMAIL PROTECTED] wrote:String userName = root; String password = ; String URL = jdbc:mysql://l/AdressBook; Are you sure this is correct? You are connecting to a MySQL server at URL 1 and db AdressBook as root without a password... you should: - secure MySQL root with a password - create a new user with rights limited to db AdressBook and allow this user to connect from % for now - set a password for that user - reload user table! - change your url to the correct server, e.g. jdbc:mysql//localhost:3306/AdressBook - try again HTH, jan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - Yahoo!

Communication between Apache an Tomcat
Hi everyone, I cannot access my servlet from Apache but I can access my jsp.I am using Apache 1.3.33, jk_mod1.3 en Tomcat 4.1.27 on Linux (Debian Serge).Tomcat is running and I can access all my servlets and jsp via port 8080.Apache is also running.I can access all my jsp via Apache which proves thst my jk_mod is working but I can`t access my servlet.I got 404 error Can anyone help me Thanks in advance Byfour - Yahoo!

Re: Communication between Apache an Tomcat
Sorry for the long Httpd.conf file.This is the jk_mod section in the Httpd.config file IfModule mod_jk.c JkWorkersFile /etc/tomcat4/jk/workers.properties JkLogFile /var/log/apache/mod_jk.log JkLogLevel info JkMount /*.jsp ajp13 JkMount /servlet/* ajp13 Directory `/var/www` Options Indexes FollowSymLinks /Directory /IfModule Mirek Kopriva [EMAIL PROTECTED] wrote: Hi, Looks like it's the configuration of mod_jk in apache. Not sure what is wrong (If you'd atach the configuration files it would be easier to help you). But my guess is the problem is setting of JkMount directive. looks like you have: 'JkMount /*.jsp worker' only while you should have: JkMount /your_context or /* worker or something like that.
