Consider: @Entity public class M { @ManyToMany private List<E> es = new ArrayList<E>(); private E newE;
I have a method that builds and runs a Criteria query. The query does what I want it to, specifically it filters (and sorts) records based on user input.
I have two online-systems running. Both of them are using eclipselink. The first system is a administration-system, where the prices for the second application are managed.
Obviously, there is plenty out there about MyISAM vs InnoDB engine selection, but I couldn\'t find anything specific to JPA2.
I need to bind at maximum 8 variables. Each one of them could be null. Is there any recommended way to achieve this? I know that开发者_如何转开发 I could simply check for null, but this seems tedious.
I have been developing my web-app using JPA 2.0 implementation EclipseLink 2.2.0.I finally got around to running multi-threaded code and I got this exception:
Let say you have a class with a java.util.Date field. Maybe a To do class or an Event planner class. @Temporal(TemporalType.TIMESTAMP)
I am looking for a template project a tutorial of how to build Spring 3 + EJB 3.1 + JPA 2 application. Any references or advices warmly appricated.
I have a query that I have been trying to turn into a CriteraQuery, but I don\'t get how to code the \"IN\" term of the query.
I\'m not even sure this is possible but I figured it\'s worth asking.I\'ve been using native query\'s for this for a long time.
