Sebastian,
Thanks for your reply. I did know about environment variables. I would be
concerned about someone doing a “ps -ef” on the box and getting the password
from the command line arguments. I will keep looking.
Regards,

You can use environment variables (and setenv.sh/.bat). Example:
Set your environment variable:
> export USER_NAME=user1
Modify / create setenv.sh:
JAVA_OPTS=-Dcustom_user_name=${USER_NAME}
Modify your context.xml:
[...] <Resource … " type="javax.sql.DataSource" …
username="${custom_user_name}" [...]
I didn't test it, but it should work like this.
