Should I use Glassfish as an open source app server in the Enterprise to use with Spring or look at other options?

What is the best choice for an open source Enterprise-level application server when using Java 6 and Spring 3.1? Glassfish or JBOSS? Looking for good support e.g. online documentation, features, ease 开发者_StackOverflow中文版of use and set up, good performance, security, scalability, high availability features etc. that an enterprise would require. Enterprise being a large commercial or government client.

Are you using EJBs? If not, I would recommend jetty. jetty is a very light-weight container for doing most of the exploration/testing you would want to do in a project. Another plus that jetty delivers is that it is configured with only the most basic features enabled/configured by default.

Are you using Maven? If so, I would also recommend jetty-maven-plugin. In the past, I've had some success with using the jetty-maven-plugin for local testing on a previous project.
