Devoxx Day Three - part 1

In the keynote I learned:

• Oracle is committed to Java (or at least wants to give us that message).
• Java EE 6 will be great, as will GlassFish v3 and it's coming 10/12/2009.
• Adobe wants developers to switch to their platform which has great tools to benefit the interaction between designers and developers. Definitely something to consider if you want a cool client app.

Then I followed the "ESB's & web services in practice" because I liked the previous talk of Nicolai Josuttis. Learned some things but still the talk looked a bit too much too the one of yesterday. SOA is a solution to a problem (how to connect heterogeneous systems) but not one without its own issues. It was a bit more in depth, discussing problems with ESB and WSDL instead of SOA in general. This showed to me that it is complicated and for example if you only have 5 systems, point to point could be preferable to an intermediate ESB. A pragmatic approach is probably the best. I remember doing routing of messages from and to different systems using just a plain appllication server without any other framework/tool/product. Using an ESB for just that would have been too much overhead.
