In this session Patrick explores the new Java Persistence API, and examine some common practices for how to write Spring applications that use JPA. Patrick will focus more on API usage than on mapping configuration, and will look at the bootstrapping and runtime behavior of JPA applications. You will learn about JPA's optimistic locking semantics, including the benefits of optimistic read locks. Patrick looks at when it's appropriate to use the different facilities of the Java Persistence Query Language (JPQL), and also discusses common extensions to the spec, including performance caching, pessimistic locking, and fetch strategies.
Patrick Linskey has been involved in object/relational mapping for 6+ years. As the founder and CTO of SolarMetric, Patrick drove the technical direction of the company and oversaw the development of Kodo. Now at BEA, he leads the EJB team in designing and implementation of the WebLogic Server EJB solution. Patrick is one of the leaders on the EJB3 and the JDO specification teams, and is BEA's representative on the EJB3 expert group. Patrick is involved in several industry consortia, serving as a luminary on JDOcentral and as the moderator on forthcoming JavaPersistence.com. He has been the face of standards-based persistence, having evangelized JDO and EJB Persistence in hundreds of talks throughout the world. Patrick is co-author of Bitter EJB, and is on the JAOO Conference Program Committee. Patrick has also worked for TechTrader, MIT's Media Lab and Bank One in various technical roles. Under Patrick's leadership, Kodo has become the market leading JDO implementation with over 450 customers throughout the world spanning all industries.
Java Persistence 2.0— One of the key outcomes of Java EE 5 / EJB 3.0 was the introduction of the Java Persistence API. JPA is a new standard API for Java persistence and object/relational mapping that supports use in both Java EE and Java SE environments.
JSR 318 - Enterprise JavaBeans 3.1— Enterprise JavaBeans is an architecture for the development and deployment of component-based business applications. Applications written using the Enterprise JavaBeans architecture are scalable, transactional, and multi-user secure.
Advanced Topics in JPA— In this talk we will introduce a few of the common features and use them as a platform on which we can discuss some of the higher order JPA topics. As part of this discussion we will show how to use multiple persistence units, define and tune identifier generators, create and invoke native queries, and use XML mapping files for overriding annotation metadata. We will also show how JPA can be used in Java SE and Spring environments.
Java EE 5 Blueprints (JPA)— The Java BluePrints projects presents the programming model, guidelines and examples for designing enterprise quality applications and web services using Java technologies. Some of the areas covered are Ajax-enabled Web 2.0 applications, Persistence, JavaServer Faces, SOA with BPEL, and WS-Security. This talk will focus on the Java Persistence API.
EJB3 Interceptors— The EJB 3.0 spec defines the ability to apply custom made interceptors to the business methods of your session and message driven beans (and of course to the JBoss @Service and @Consumer beans). EJB 3.0 interceptors take the form of methods annotated with the @javax.ejb.AroundInvoke annotation. This JavaPolis talk by Bill Burke covers this part of the EJB3 spec.
