Subject org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null'
Date Mon, 31 Jul 2006 18:46:06 GMT
Hi there:
I am using tomcat 5.5.17 and SQL Server 2000 database with SQL Server 2005 JDBC Driver.  OS
is Windows XP professional.  I have configured web.xml in WEB-INF directory and context.xml
in META-INF directory of my application. Both are attached below with this email. I have a
login.jsp page that asks for username and password... and when submit is hit, it gives the
following error.
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for
connect URL 'null' 
I tried to google and tried the suggestion given but any of them doesn't seem to work. Is
there anything wrong with my configuration? PLEASE HELP...it is higly appreciated. If something
is not clear, please get back to me.  Thank you so much.
context.xml file looks like this...
<?xml version="1.0" encoding="UTF-8"?>
