The Java Persistence API (JPA) is fast becoming the popular choice for object-relational persistence not only in Java EE environments but also in enterprise applications that make use of other technologies, such as Spring. Since the JPA standard has taken hold, the developer base has gotten more experienced with the persistence model, and the questions that arise are now more of an intermediate or advanced nature.
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.
While attendees that have some experience using JPA will profit from this talk, even those who are interested in JPA, but who have not yet started writing applications with it, could also enjoy it. Some kind of experience with Java persistence would be beneficial, though.
Mike Keith was the co-specification lead for EJB 3.0 (JSR 220) and a member of the Java EE 5 expert group (JSR 244). He co-authored the premier JPA reference book called Pro EJB 3: Java Persistence API and has over 15 years of teaching, research and development experience in object-oriented and distributed systems, specializing in object persistence. He is currently a Java and persistence architect for Oracle and is a popular speaker at numerous conferences and events around the world.
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.
Writing JPA applications— 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.
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.
Enterprise Development with JPA— Standardization of persistence inside of the Java EE platform, as well as in the SE environment, will finally provide enterprise applications with the ability to write to one API and be able to run on the vendor of their choice. This talk covers best practices and common usage patterns of the Java Persistence API in conjunction with a Java EE application server.
Using the Java Persistence API— Standardization of persistence inside of the Java EE platform, as well as in the SE environment, will finally provide enterprise applications with the ability to write to one API and be able to run on the vendor of their choice.
