Glassfish Clustering Setup
I'm a complete novice to clustering so would like some tips in its architecture and how to configure a simple setup with Glassfish (preferably using the nice admin interface).
From what I've read, the bit that really baffles me is why the Sun Java Web Server is required when Glassfish can service HTTP requests on its own. Why is, what is effectively a third party bit of software, required? Why can't you just create, for example, three instances of glassfish then link them together to as one logical cluster.
Any infomation you could give would really help a confused individual!
