BEA is holding a series of half-day developer seminars in a number of cities in Europe and the Americas, focussed on building enterprise mashups with their new/rebranded en.terpri.se platform. I was excited to see that one will be in Toronto, since it seems like vendors always skip my hometown; however, I’m less excited to see that it’s the only one of the seminars to be held at the same time as their own user conference, which means that I have to miss it.
