eclipselink

This is a standalone java application, not web application. So when I persist the object like this public <T> T create(T t) { em.getTransaction().begin(); em.persist(t); em.flush(); em.getTransaction().commit(); return t; } The id inside the T t object is still null, even though a new row with correct data and id is created correctly inside the database. Usually in my web app that utilize @EJB , the id available right after I persist, since it persist the entity object into my persistence context, I am not sure if I have my persistence context here? This is how I mapped my id inside my @Entity

I'm getting exception when trying to execute test Please help . Thank you in advance I'm using : Java 7 , EclipseLink 2.5.0-SNAPSHOT, Spring 3.2.4 Test configuration file : <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" p:location="classpath:jdbc.properties" /> <bean id="tttDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" p:driverClassName="${jdbc.driverClassName}" p:url="${jdbc.url}" p:username="${jdbc.username}" p:password="${jdbc.password}" /> <bean id="loadTimeWeaver" class="org.springframework

I have an entity named User which has the following field called roles : @ManyToMany @JoinTable( name = "user_role", joinColumns = {@JoinColumn(name = "user_id", nullable = false)}, inverseJoinColumns = {@JoinColumn(name = "role_id", nullable = false)} ) private List<Role> roles; I load the User via the use of a service method and the service method is wrapped in a transaction (JTA). After calling the service method and retrieving the User , I access this role field outside of the transaction that was used to load the User entity. I was expecting to get an error because the eclipselink

I would like to have the following returned to the browser (view source) <content> <![CDATA[Please show this inside a unescaped CDATA tag]]> </content> But I acutally get <content> Please show this inside a unescaped CDATA tag </content> If, I change the value of content to be &lt ;![CDATA[Please show this inside a unescaped CDATA tag]]&gt ; , the less than and the greater than for the tag are escaped.

I am using the Netbeans IDE 8.0.2 and eclipselink 2.5.2. This occurring exception below when opening a connection, the problem is that this does not happen every time. The entity described in exception "Departmento" exactly follows the pattern of the other classes being that our system already contain approximately 500 entity classes and only in the new classes are taking place this exception. This entity was generated by that option "Entity Classes from Database" of Netbeans and added to the persistense XML ... Caused by: javax.persistence.PersistenceException: Exception [EclipseLink-28018]

I have class named AbstractEntity, which is annotated with @MappedSuperclass. Then I have a class named User (@Entity) which extends AbstractEntity. Both of these exist in a package named foo.bar.framework. When I use these two classes, everything works just fine. But now I've imported a jar containing these files to another project. I'd like to reuse the User class and expand it with a few additional fields. I thought that @Entity public class User extends foo.bar.framework.User would do the trick, but I found out that this implementation of the User only inherits the fields from

In my application, when user logs in to the system the system reads some setting from DB and stores them on user's session. The system is performing this action by a JPA query using EclipseLink (JPA 2.0). When I change some settings in DB, and sign in again, the query returns the previous results. It seems that EclipseLink is caching the results. I have used this to correct this behavior but it does not work : query.setHint(QueryHints.cache_usage,cacheUsage.no_cache); If you want to set query hints, the docs recommend doing: query.setHint("javax.persistence.cache.storeMode", "REFRESH"); You
