Nathan, I am using Spring MVC, but the problem appears to be somwhat similar. The blank screen was caused by some exception, I have no idea why I could not find any signes of the exception until I turned off the GZIP filter. Once I did that I could see the error page and find the problem. My issue was that for an application generated using appfuse:gen. The generated web app has a footer.jsp which uses the following tag:
<authz:authentication operation="fullName"/> which if the principal implements UserDetails, will call the "getFullName" on it. Problem is when we use LDAP authentication, the UserDetails are in org.acegisecurity.userdetails.ldap.LdapUserDetailsImpl, which doesn't have a getFullName method, which thru a JspException which for some unknown reason resulted in a zero size response... So I changed the footer.jsp to reference the "Username" operation which is part of the UserDetails interface and should therefore work no matter what the implementation is...
