Hello tomcats !! :) A quick question as I tackle configuring jndi resource 
for first time: I was referred to using jndi in production environmrnt snd 
hsve noted through documentation found in  test server that there are 3 
possible places to define jndi resources:
1)the server .xml(for every webapp in server if I am correct.

As I am planning on only using this resource for multiple webapps in same 
domain, am I right in asuming server.xml is correct choice to define jndi 

In addition I am to define jndi used in server.xml again in web.xml?

I now need to know how / where to configure parameters for mysql connections 
or are the defaults acceptable for production?
