Packt Publishing has published a new book on Java Business Integration, titled, Service Oriented Java Business Integration. 
The book concentrates on leveraging Java Business Integration (JBI) for addressing real world integration problems with examples. Business level integration in Java needs to address integrating multiple flavors of business components including POJO, EJB, Web Services, JMS, etc. The book explains all the above scenarios, using open source Apache ServiceMix as the ESB framework. 
This book discusses:
  • Assemble services and port it across containers using JBI
  • Expose EJB as WSDL compliant service across firewalls
  • Bind remote services onto the ESB to be consumed internally
  • Expose local components in ESB like POJO as WSDL compliant services to be accessible externally.
  • Provide a web service gateway for external consumers
  • Access web services over reliable transport channel like JMS
  • Implement web service versioning using ESB
  • Implement service aggregation at ESB
  • Transactions, Security, Clustering & JMS in ESB
It is aimed at Java developers and integration architects aiming to become proficient with Java Business Integration (JBI) standard, who are expected to have some experience with Java and to have developed and deployed applications in the past, but need no previous knowledge of JBI. The book can also be useful to anyone, who has been having a hard time understanding ESB and how it differs from other architectures and to understand its position in SOA.
