A free Commercial-Use Application server for Java EE? [closed]

Question

Is there a free Commercial-Use Application-Server ?

I found a chart on Wikipedia("Comparison of application servers"), which says that JSAS (now GlassFish) and IBM WebSphere are free.

I am not sure about this, but it seems that:

• GlassFish is no longer free.
• WebSphere is not totally free, because of socket pricing(?).

Am I correct? Is Apache Geronimo is free for commercial use?
