  Creating a Web Application with Ant and Tomcat 4
Subject:   Name jdbc is not bound in this Context
Date:   2003-01-26 14:40:00
From:   anonymous2
I am getting this error in my log file. I built the app from Ant with no problems. Do I need to reference the context.xml in the web.xml?


This is the full error:


2003-01-26 16:29:33 Couldn't create addressesDB sttribute: Couldn't open connection to Public database: Name jdbc is not bound in this Context


I also get this error that may be related.

    Tom,

    If you have not put your database's JDBC driver file in Tomcat's common/lib directory, as instructed, you get the message "Couldn't create addressesDB sttribute: Couldn't open connection to Public database: Cannot load JDBC driver class 'org.gjt.mm.mysql.Driver'". So I don't think this is your problem, but please check it anyway.

    Otherwise, you can view your Tomcat configuration by pointing your browser at http://localhost:8080/admin and looking at AddressBook's Context and Data Source Panels [see figures 8 & 9]. Do these panels look correct?

    You do not need to reference the context.xml in the web.xml. The information in context.xml gets put in Tomcat's conf/server.xml file automatically by the Ant/Tomcat admin process. Check server.xml out with your favourite text editor. Does this look correct?

    Finally, what versions of OS, MySQL, JDBC driver, Tomcat and Ant are you using?

    Cheers,
    Paul
