I primarily use Tomcat and Glassfish for Java EE development at work, but was wondering if anyone knew of any small application servers like Cassini for ASP.NET that would make building and testing faster? I would still eventually deploy to one of our production tomcat/glassfish servers, but would prefer something that is simpler and quicker.
I am probably going to take jetty and geronimo for a spin, any others I should check out?
