, the JBoss Netbeans IDE is available with support for EJB3/JPA. The announcement
is on the JBoss site, downloads
are on the Netbeans site.
So now there are two easy ways to get started with EJB3/JPA and both are based on Netbeans: 1) JBoss Netbeans IDE and 2) Netbeans 5.5 plus the Enterprise Pack, which includes Glassfish/Sun Java App Server. Currently, both IDEs are based on Netbeans 5.5 beta 2 but don't let that scare you away.
I've been using Netbeans 5.5 beta 2 on my Solaris box for a week or so
now and it's quite stable. On my Mac, not so much -- beta 2 worked fine
until I installed the Enterprise Pack and then I started to get all
sorts of slow downs and very strange repaint problems in the tree-view.
I upgraded to a Q-Build (the 20060818 one) and now it's quite usable --
still a little sluggish but then again everything seems sluggish on my
Powerbook these days.
