This blog will look at building Glassfish 4.0.1 from source and configuring NetBeans 8.0 to then use, modify, and debug it.

GlassFish 4.1 was released a couple of months ago now, bringing with it a large number of welcome bug fixes and improvements. As the Payara Open Source project was born from it, it would be remiss of us not give all of you who maintain an interest in GlassFish a brief overview of some of the things that have changed or been updated since 4.0.
