Alas, I do not have code to the JDBCRealm =( I figured that this would be a cut-and-dried problem -- either the JDBCRealm implementation or perhaps my driver behaving poorly. In either case, I figured someone would be able to tell right off my my description, but perhaps I described the circumstance poorly.
It happens when I visit a page that has a security constraint. I'm never offered a login dialog. I'm using BASIC authentication - no SSL -- transport-guarantee is NONE. I'm just trying to get the BASIC auth down and then move on to configuring SSL and doing it properly via form-based login.
