Introducing EclipseLink--the Eclipse Persistence Services Project (Full Monty)
The creation of EclipseLink, the Eclipse Persistence Services Project, signals the inauguration of a new generation of Java persistence where all of the dominant persistence standards are implemented and accessible from a single source. EclipseLink is composed of a set of separate runtime components that can be used in both clients and servers, and is the first open source project to offer a full suite of persistence technologies. By supporting all of the popular standards, including object-relational mapping using the Java Persistence API (JPA), object-to-XML mapping through the Java API for XML Binding (JAXB), and loosely bound Service Data Objects (SDO) that bridge the relational and XML worlds, EclipseLink will provide the most comprehensive persistence platform available. Equally compelling is the fact that these technologies are offered with a rich array of feature extensions and high-end performance options.
In this session, attendees will learn what EclipseLink is, the standard technologies it implements, and how these technologies can be used separately or together to meet advanced and diverse application requirements. We will show examples of how to use EclipseLink to map Java objects in object-relational and object-XML contexts, and how it can be used in any runtime environment, including Eclipse RCP, Java SE, Java EE, Spring and Tomcat.
Developing with JPA and JAXB
Two important Java persistence standards that are relevant in modern enterprise applications are the Java Persistence API (JPA), which is part of Java EE, and the Java Architecture for XML Binding (JAXB), available separately in Java SE 5 and included within Java SE 6. Each of these standards has solved a similar problem that exists in different data domains. JPA offers developers a standard persistence solution for mapping and accessing relational data within a Java object model. JAXB offers them the ability to bind their Java model to XML documents based on XML schema mappings. Both of these solutions enable using Java domain objects to define and maintain business logic. Combining JPA usage with JAXB is an important domain-driven design solution where the mapping to an underlying relational schema and the ability to render the model in XML is very natural for today's service-based development.
This session will demonstrate how these two persistence standards can be combined effectively to leverage a common domain model, while still offering the flexibility necessary to handle diverse data representation requirements. The shared domain model and the flexible mapping solutions eliminate costly transformation logic and embrace the rich domain model where application state and behaviour can be developed and shared across multiple application components and services.
Eclipse JPA: Getting Chocolate in the Peanut Butter
Eclipse has lived most of its life as an IDE, and most will agree that it has achieved a great deal of success along the way. However, Eclipse is now all grown up and has decided to establish itself in runtime-land as well. Counted in its runtime component arsenal is its Equinox OSGi layer, its Rich Client Platform (RCP) API, and now a full Java Persistence Platform that includes a deluxe Java Persistence API (JPA) implementation. In this talk we will learn how to use the Eclipse JPA runtime layer both inside and outside Eclipse. We will see how the Eclipse Dali tooling assists in developing a JPA application, and also see what configuration metadata might be needed to get the application running. As part of the discussion we will examine the difference between writing applications targeted for a full Java EE 5 container and those built to run in a standalone Java SE environment.
Attendees are not required to have experience with JPA, but having some kind of Java persistence knowledge or object-relational mapping experience will help.
Building JPA Applications with EclipseLink and Dali
With the release of Dali JPA Tools 1.0 and the availability of Eclipse JPA from the EclipseLink project, a complete JPA development platform and runtime environment are now available from Eclipse. In this talk we'll learn how to use the Eclipse JPA runtime but also see how the Dali tooling provides a platform for developing portable persistence applications across all compliant JPA providers. We'll look at JPA object-relational mappings and what configuration metadata is needed to get an application up and running. As part of the discussion we'll examine the difference between writing applications targeted for a full Java EE 5 container and those built to run in a standalone Java SE environment and how Dali's integration with the Web Tools Platform supports development for a variety of runtime environments.
TUTORIAL: JPA Development with Dali and EclipseLink
With the release of Dali Java Persistence Tools 1.0 and the availability of Eclipse Java Persistence API (JPA) implementation from the EclipseLink project, a complete JPA development platform and runtime environment are now available from Eclipse. In this tutorial attendees will learn how to productively develop and maintain high performance Java applications leveraging a relational database. Project Dali's JPA tooling included in WTP (Europa) offers an excellent environment for defining and managed the object-relational mappings and additional runtime metadata. This rich development environment coupled with the Eclipse Persistence Services Project (EclipseLink)'s JPA implementation and rich extensions to address performance, scalability, legacy databases, and leverage advanced features of the underlying database gives developers a winning combination.
This tutorial will walk through the development of a sample application illustrating the design-time features of Dali and the runtime capabilities of EclipseLink. Attendees will leave with a fully functioning example they can use to better understand these important technologies.
Developing JPA Applications with NetBeans and EclipseLink
The NetBeans IDE offers developers a productive and feature-rich development environment for developing and maintaining enterprise Java applications and includes support for developing with the Java Persistence API (JPA). The Eclipse Persistence Services Project (EclipseLink) is a comprehensive open-source persistence solution including implementations of the Java Persistence API (JPA), Java Architecture for XML Binding (JAXB), and Service Data Objects (SDO)--all built on a common core infrastructure. Bringing together a powerful runtime solution with a productive development environment enables developers to rapidly build and maintain their applications and services. This session will introduce developers to standard JPA development techniques and the ability to leverage provider specific extensions as illustrated through demonstrations using NetBeans.
Understanding your JPA provider's solution with respect to mapping, caching, querying, and transaction optimizations in a single node and a cluster is critical to harnessing its full capabilities. The many advanced capabilities of EclipseLink JPA will be discussed giving concrete examples of how these can be applied to address performance, scalability, and flexibility concerns. The ability to build and test EclipseLink JPA solutions in a variety of Java architectures (Java EE, Java SE, Web Containers, and Spring) will also be discussed along with their corresponding usage within the NetBeans environment.
Attendees are not required to have experience with JPA, but some knowledge of Java persistence or experience with object-relational mapping will be beneficial.
EclipseLink MOXy: The Power of XML Binding
The use of XML in Java applications is extensive and continues to grow. It's used everywhere from configuration files, JMS messaging, Web Services, and Ajax applications. Developers are faced with a number of options when dealing with XML in their Java applications. The most important question is whether to work directly with the XML DOM or to use Object-XML Mapping (OXM, a.k.a. XML Binding). Mapping XML to a domain object model simplifies Java development by allowing developers to work with rich objects instead of generic DOM elements. OXM is gaining popularity in the Java community but not all OXM frameworks are equal. When selecting an OXM framework for a project it is important to consider performance, standards compliance, usability and flexibility. In this session attendees will be introduced to OXM and to how these issues are addressed by EclipseLink MOXy, a component of the the Eclipse Java Persistence Platform. EclipseLink provides a rich OXM solution that addresses a wide range of application requirements while also providing the benefit of integration with other EclipseLink persistence capabilities.
