Tomcat uses commons-beanutils to set all the parameters of
org.apache.commons.dbcp.BasicDataSource (or actually tomcat's own
refactored copy of it) with the attributes found in the Resource element
in server.xml or one of the context.xml files.
I think Johnny is right ... set up your own db pool. You could even
pull the same trick with commons-beanutils that tomcat does, just catch
where it gets to the password and handle that separately. It's easier
and then your webapp can be more self contained and container independent.

Jevin, my curiousity got the better of me, and I tried to find it for
you....
Can see TC loading up the resource in the ResourceFactory, but it just
seems that nowhere does it actually read the password and pass it into
DBCP....
I havnt checked, but I have a feeling that the DBCP module gets the
password directly from the configuration..... I dont have the source
for DBCP, so couldnt check.
Anyway, I think its just a really bad idea.... think it will be easier
just to setup your own dB pool, and put the passwords where ever you
want, thats how I do it....
Good Luck...

Subject: How internally does a jndi resource get created?
Big picture: Trying to hide the password from the server.xml file and
instead have it in byte code in a compile version of tomcat.
I'm trying to figure out when the jndi resource is being created by
tomcat so I can change the password for a given resource. It may not
be super clean or OO style but it will work.
Tomcat is kind of overwhelming so I'm looking for help. It looks like
the HostConfig class parses the server.xml (where my database and
password is defined) and parses it from there but I'm totally lost
where it adds the Resource to JNDI lookup table.
Could someone point me in the right direction?
Cheers!
Jevin
