I've been running across quite a few blogs lately speaking about Glassfish. It appears that this great application server is being used by more people and gaining some real popularity. I've been using Glassfish since version one. Actually, prior to Project Glassfish, I used the Sun Java Application Server version 8.
I have nothing bad to say about Glassfish. It is an excellent choice for a JavaEE application server. Powerful and easy to use, this application server should not be overlooked if you are in the business of Java web development.
I have not yet tried out version 3, but I plan to do so very soon. I've been working primarily with Glassfish version 2 for the past few months. I've found it very easy to deploy JBOSS Seam applications to Glassfish even though there is no direct IDE deployment option for this setup as yet.
I will post any issues or concerns with using Glassfish V3 and JBOSS Seam...
