Are there any news on the subject? Is it possible to use SEAM with Websphere already?
Maybe someone in the Seam community who uses websphere should try it and report back. I can't speak for any of the other Seam guys, but I don't recall getting a websphere license sent to me by IBM. :)
WebSphere does not yet support EJB3, and we did not yet do the (small) amount of work required to integrate JBoss Embeddable EJB3 in WebSphere so no, not yet.
If someone wants to contribute WebSphere support for E-EJB3, that is a fairly easy task, and I can give guidance.
