I am now of the opinion that Toplink will become yet another sales driven technology (like Oracle? ) Then, we'll take a look at how Hibernate and EclipseLink fit into the picture. The main reason for this was that Hibernate depends on so many core open source libraries that other open source projects also use, that there are all kinds of version problems when the application is deployed in a JEE container, such as Tomcat or Glassfish, that uses different versions internally. However, Hibernate was also the JPA implementation that executed the lowest number of queries, although the differences in this value (3080 for Hibernate vs 3740 for Toplink Essentials) are not so extreme as for the number of inserts. In many respects Toplink is inferior to Hibernate's query implementation. JavaTpoint offers too many high quality services.
