Hibernate EntityManager implements the programming interfaces and lifecycle rules as defined by the EJB3 persistence specification. Together with Hibernate Annotations, this wrapper implements a complete (and standalone) EJB3 persistence solution on top of the mature Hibernate core. In this post I will describe how map native queries (plain SQL) using Hibernate Annotations. Hibernate Annotations supports the use of Native queries through the @NamedNativeQuery and the @SqlResultSetMapping annotations.... more »

The Spring framework provides extensive support for data access through the use of support classes (JdbcDaoSupport, JdbcTemplate etc.), and extensive exception hierarchy to wrap any platform specific SQLException into an exception in the spring exception hierarchy. Additionally Spring framework also provides good support for integrating with ORM technologies like Hibernate and iBatis etc. This post will show how to integrate Spring framework with Hibernate ORM.

Hibernate, in the end, is all about dispatching SQL statements. SQL is at the heart of communication with an RDBMS system, and it is extremely important when struggling through performance problems or other bugs, that you know what is going on. After all, knowing the executed SQL allows you to determine the number of queries to complete an O/R mapping task, not to mention that seeing SQL queries is critical to understanding how to optimize the queries via indices and other database settings.... more »

We have some queries that can potentially return a large set of data. The first pass at this put all of the data into HttpSession and allowed a non-standard h:dataGrid like component automatically do the pagination. This works fairly well for small results sets but not so well for larger result sets as it consumes too much memory and takes a while for the first page to load. (The fancy h:dataGrid like component also automatically does sorting.)... more »
