Subject: Re: Struts2 with Authentication & Security
Personally, I used to prefer container managed security, like what
Tomcat provides ->
http://tomcat.apache.org/tomcat-6.0-doc/realm-howto.html
But found that I didn't like being forced into their database schema,
so I started using ACEGI, which is now called Spring Security.
There are some that don't like it, but I actually sort of like it.
It's a very serious learning curve, but things have gotten quite a bit
better than they used to be. I am even overriding more than a few of
their stock services with my own so that I can provide a security
system quite a bit more complex than what you normally get out of the
box. In addition, Spring Security has annotations and custom tags so
that you can really get granular with your setup. If you feel like you
have a need for a sophisticated security framework, check it out. If
you just want to protect a few pages/requests, then Spring Security is
probably overkill.
