jdbc realm, form-login-config, Tomcat and db connection error

Question

My tomcat 5.5 server has a classic FORM based authentication method with a JDBC-REALM. Everything works fine but I would like to differentiate the login fail (wrong userId or password) from the connection error.

So I've:

<form-login-config>
<form-login-page>/secure/login.jsp</form-login-page>
<form-error-page>/secure/errorPage.jsp</form-error-page>
</form-login-config>

How can I intercept a SQL-Exception rather than an incorrect login in the errorPage.jsp?

Thanks in advance.
