On JNDI connection problems: We'll need to see more. Specifically the
jsp code calling for the sql connection and the web.xml. A full stack
trace of the error you get would be excellent as well. Lastly, confirm
the mysql jdbc driver is in common/lib of the tomcat directory, not
WEB-INF/lib of your webapp.
On configuring in server.xml, this is fast becoming a file that should
be left alone for all but general server configuration. JNDI resources
should be defined either in your [webapp_name].xml file in
conf/Catalina/localhost or a context.xml file placed in the META-INF
directory of a .war file unless you really want the resource available
to all web applications in tomcat.
On the admin webapp problems: I don't use it, so I can't help. Maybe
someone else could comment?

hai david,
thank for sending those help files.now we are using tomcat 5.0.x.
our database is mysql and the Driver is com.sql.jdbc.Driver.
when i am calling the jsp pages in my project its working fine,if i am
trying to communicate with database errorpage is thrown.
******************
i had tried to create new *jndi* name through tomcat admin page.but the
changes are not reflecting in the usr/j-tomcat5.0/config/server.xml
instead linux is creating a new xml file named as server.xml(plus date
and
time of creation) inthe same directory Even in that xml file also i
cont
see the jndi name and other changes, which i had done through admin page.
i want to know how to configure the jndi name in the server.xml file
since i am new to linux with tomcat i cont proceed with things, please
guide
me in the right direction
bye
with regards

This is well documented on the tomcat site. What you've included below
works on tomcat 5.0, but not 5.5. See the online docs:
Tomcat 5.5 --
http://tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html
Tomcat 5.0 --
http://tomcat.apache.org/tomcat-5.0-doc/jndi-datasource-examples-howto.html
What version of tomcat are you working with?
