I think that is covered below in the application.xml file excerpt
for the Resource. Otherwise I am not sure what you are asking?

It appears we have problems getting connections from the pool sometimes.
I am working on getting more information about that (log files). No
special exceptions occur. The problems start to occur after running a
couple of minutes. In case, I did not say this - this application was
fully running before we converted DB and application to UTF-8 for French
(et al) characters.

All JSP files start with:

<%@page contentType="text/html; charset=UTF-8" language="java"%>

No changes made to Java files for UTF-8
- some of these are directly in the web.xml file as servlets, not just
usage beans
web.xml also has it's first line as
<?xml version="1.0" encoding="UTF-8"?>
