Its yr choice waht u want to choose.
Both seems to work..
With JBoss-4.o i would say that use JBOSS-IDE if u are using new web services stack as lomboz doesn't have the support for that yet only for Axis style webs services.
But you can get Eclipse "wtp - web tools project" plugin for new webe services stack in JBoss 4.0.
I normally have both of them in my Eclipse.. as JBoss-IDE provides content help for xdoclet tags.
I haven't tried new version of JBoss-IDE, should be good.
Thanks for your help, and your time!.
According what you say, I will prove JBOSS-IDE.
I rely on this config and I expect that allows me to develop EJB, compile and deploy on JBOSS server.
