Hello,
I have read a lot of articles and several topics in this forum about how to choose a
java application server, but I still have some doubts. In the real world I have only used GlassFish and I really like it so far.
The main requirements of my application server are: flexible configuration, support for a extremely high number of concurrent users. It will be a system for the mobile communications industry, so it must have high availability as well.
Open Source Applications Servers are my only option.
Thank you very much for your advise.
