JavaOne

Today was my last day at JavaOne. It was an overall very good week.

On the technical side I learned more about the Java Persistence API (JAP) that is the standard API for the management of persistence and object/relational mapping in Java EE 5 platform. JAP should eventually replace JDO.

Service data interaction is also simplified with Service Data Objects SDO. the SDO API lets you work with data from multiple data sources, including relational databases, entity EJB components, XML pages, Web services, etc. SDO also takes care of data change summaries that are used at backend update time to apply the changes back to the data source. This is all cool and better described here and also implemented by this excellent BEA Aqualogic Data Service Platform.

Obviously AJAX was an important theme and I have got the feeling that the trend is to develop Web GUI using AJAX enabled JSF components.

Otherwise, it was also good to get a broad overview of the current product offering. Note that Sonic did not attend JavaOne this year. Hum, I wonder why? This being said, I was not impressed by Fiorano ESB offering.

On the social life side, the JBoss party was excellent and the JavaOne one a bit too big, it is difficult to entertain and feed 14 000 persons.
