Reg. community, the list cannot be complete without the SO tag - http://stackoverflow.com/questions/tagged/java

Cool. What about java related IRC channels?

[mindcrime]

On Freenode:

##java

#spring

#eclipse

#jboss

#hibernate

#lucene

are ones I sometimes lurk in, that are fairly active. The Triangle (NC) Java User's Group also have a channel, but it's not terribly active most of the time.

#trijug (again, on Freenode)

Also, if you're not already in #startups, it's a channel full of HN users... might be of interest to ya.

Sweet! Thanks for the great list.

I would like to put in a plug for EFNet #java - idle there long enough and you may learn some things.
