JBossWorld conference has started at Berlin. Rooms were already full of people with good energy when first sessions started at 12:00. Laptop workshop sessions provided introduction to new JBoss components through practical hands-on examples. CDs with pre written code examples were given to the audience and the participants made needed changes to the code to make their first applications using e.g. JBoss SEAM. The exercise consisted of adding the necessary annotations and class inclusions to make the applications to include advanced properties such as object persistence. The session was held by Mark Spritzler.
Tom Baeyens gave three presentations about business processes. The first was introduction to JBoss jBPM, describing all relevant terminologies and most common specifications. The next presentations were more about JBoss implementation of BPM and how it works with SOA. Interesting talks with lots of information.
Service Oriented Architecture is the current way of doing things. The JBossWorld conference has a special SOA track lasting the whole three-day event. Today started with introductions to the SOA concept and relevant building blocks: web services and JBoss Enteprise Service Bus (ESB). The next days are going to give much more intense look into SOA.
The use of annotations seemed to be characteristics for many new Java components that were introduced. Usually using the annotations remove the need to do configurations through hand editing the XML-files. Complex functionality can then be included to the applications with introducing only small changes to the application code.
JBoss Messaging library was presented by Tim Fox and the new architecture comprises performance-improving design as well as removes many limitations that were present in the preceding MQ component. The messaging incorporates state of the art design including the use of NIO and SEDA for performance and architecture which leverages functionality of other JBoss libraries, such as transactions and group communication.
More information here tomorrow…
