In this virtual panel, the editors of InfoQ.com (Floyd Marinescu) and ODBMS.org (Roberto V. Zicari) asked a group of leading persistence solution architects their views on the current state of the union in persistence in the Java community.
In this article, Eelco Visser summarizes his approach to design WebDSL, a domain-specific language for developing dynamic web applications with a rich data model with a target architecture based on JBoss's Seam. He discusses paradigms and challenges of Language Engineering while sharing some of the lessons he learned along the way.
The open source Java persistence platform JPOX has become DataNucleus for its future direction, due to the significant changes in scope of the project since its initiation. The baseline product DataNucleus AccessPlatform, provides persistence to RDBMS, db4o, XML, LDAP and Excel datastores via JDO or JPA APIs.
java.net is hosting an article written by Sharad Acharya titled "Java Persistence Framework: Which, When, and What?" that compares four popular persistence frameworks: CMP Entity EJBs, JPA, Hibernate, and TopLink. Acharya discusses each technology and summarizes his findings in a matrix.
Srini & Kavitha Penchikala provide an overview of the support provided by Spring framework in the areas of unit and integration testing. I will use a sample loan processing web application to help the readers in implementing an Agile Testing framework in a typical Java EE application and how to use Spring test classes to test the application functionality.
Spring 2.0 was initially supposed to come out in June/July, why the delay? InfoQ interviewed the Spring team - based on massive community feedback, the team has chosen to delay the launch to Sept 26th in order work on asynchronous JMS capabilities, JPA, the new JSP form tag library, OSGi integration, documentation, and backwards compatibility.
At The Spring Experience conference, InfoQ caught up with Patrick Linskey of BEA to discuss the current status of the Apache OpenJPA project. Linskey explains where OpenJPA came from, how it fits into the Object\Relational Mapping space, the differentiating features that OpenJPA provides, the JPA specification, and future plans for OpenJPA.
In this interview co spec lead Mike Keith discusses the current state of EJB 3. He covers how the community has drove the development of the EJB 3 spec as well as the praises and criticisms that have developed along the way. Keith also comments on the evolution of the specification to be work better with pojo's and embrace newer ideas such as dependency injection.
This talk covers the key aspects of the Java Persistence API and its role in the development of EJB 3 app, including use of the EntityManager API, persistence units and persistence contexts, queries, object/relational mapping, and how the combination of EJB 3 and Java Persistence facilitates the development of Java EE applications.
