The biggest disadvantage of bpel is the missing feature of human interaction integration. BPEL itself, according to the current standard WS-BPEL 2.0, is designed for fully automated processes only. But as real world projects show, most business processes have the need to do some activities non-automated - e.g. to get some decision from a real person. Therefore we have a whitepaper, BPEL4People, since several years now. Most vendors of bpel engines implemented custom solutions to handle human task stuff - like the BPEL4People whitepaper describes.
Now the scene is moving on: We will get a spec called WS-HT (Human Task), which describes a service interface for a human task workflow service, basically. Then we get WS-B4P (BPEL4People) which describes how to integrate WS-HT in WS-BPEL 2.0.
That's great news. So we have one more useful component for our SOA world.

Hopefully, we will see these ideas at the OASIS site soon...

IDE Shoot-out at JUG Cologne
This was a very interesting event yesterday in the rooms of the university of cologne. Michael Hüttermann organized this special JUG Cologne event, where four of the major IDEs were presented. Participants:
1) NetBeans
Roman Strobl focused on the RichClient plattform, Java EE development support and Ruby integration.
2) Eclipse
Wayne Beaton presented on Ubuntu with OpenOffice, which didn't work too well. But no problem, the coolness factor made him go. He focused on the whole Eclipse eco system. Eclipse is not only an IDE, but used for lot's of other things, too. A highlight was the Europa release which bundels about 20 subproject in on e new release. If that's a "feature"? I think it's the only way to address the "plugin hell" Eclipse is facing more and more with stuff being not compatible with each other.
3) JDeveloper
Frank Nimphius concentrated on the "one-tool-for-all-tasks" message. JDeveloper today covers the whole lifecycle needed in development. Further focus was on Java EE development (EJB3, JPA) and on the integrated Application Development Framework (ADF).
4) IntelliJ
IntelliJ was the only commercial IDE presented on this event. Why is this product different? Well, JetBrains is very proud of its innovation (they had a lot of the cool IDE features at first, all others copied them), they have a brilliant code editor and what was interesting: they have a team of only 16 software engineers doing all the feature stuff and for that, they can react very fast on new ideas.
So, was there a winner? In my opinion: no. Every developer can take the tool he likes and gets all the features he needs in every case. Good, to have the choice... Outstanding features? Well, perhaps the editor of IntelliJ and the drag-and-drop development feeling of the JDeveloper ADF stuff for JSF development. Both worth a look.
