This article discusses an implementation strategy that illustrates how organizations can use JMS and J2EE Connector technologies to reuse their infrastructure and lay a foundation that will let them reap the business and agility benefits of SOA. For a Service Oriented Architecture (SOA) to be truly resilient, asynchrony must be built into its fabric. Most large organizations, however, have already invested in a back-end messaging infrastructure using products such as MQ Series, Tibco JMS, Oracle Advanced Queuing, Sonic JMS, or SwiftMQ. They don't want to replace that infrastructure to get to SOA; they want to reuse it. Enter J2EE 1.4 with two key technologies to enable Web Services and messaging infrastructure reuse: JAX-RPC, the built-in interoperability-tested J2EE API for building SOAP-based Web Services; and the J2EE Connector Architecture, now designed to supp...

Bringing Advanced Transaction Capabilities to Spring Applications

The Spring Framework provides a consistent abstraction for transaction management that delivers the following benefits: •  A consistent programming model across different transaction APIs such as JTA, JDBC, Toplink, Hibernate, JPA, and JDO •  Declarative transaction management •  A simple API for programmatic transaction management rather than a number of complex transaction APIs such as JTA •  Integration with Spring's various data access abstractions. This article discusses Spring's transaction management facilities and the common use cases in Spring where an ex... (more)
