If you forget the fact that JBoss is free and open source, would you choose it over BEA's Weblogic and IBM's Websphere? If you'd do, why ? (from a technical standpoint).
As an extra question, what is the worst problem you see for a company adopting JBoss today? What do you thing is its worst flaw(s). To be a real answer, it needs to be sincere
In my company we decided to migrate to JBOSS because the great support that it offers us. We were having very specific issues and when we were asking support for a specific vendor, we always were answered by help desk with people that know only about business, not about development. Using JBOSS�s support, we could talk directly with some developers whose could solve our specific issues. The costs with support were a little bit fewer than if we used an no free Application Server, but the quality of the service supplied was infinitely superior.
