Disabling EclipseLink cache

由 余生长醉 提交于 2019-12-07 06:50:45
问题 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); 回答1: If you want to set

Is there a way to suppress FindBugs from generating warnings on code generated by static weaving?

由 时间秒杀一切 提交于 2019-12-07 05:41:36
问题 I'm getting what I think are false positives from FindBugs (2.0.2) and Sonar (3.7.3) on code that is being generated via static weaving of EclipseLink (2.5.1) JPA entities. Specifically, I am seeing multiple occurrences of ES_COMPARING_PARAMETER_STRING_WITH_EQ Comparison of String parameter using == or != in com.test.domain.MyEntity._persistence_set(String, Object) and URV_INHERITED_METHOD_WITH_RELATED_TYPES Inherited method com.test.domain.MyEntity._persistence_get(String) returns more

Extending an entity

由 随声附和 提交于 2019-12-07 05:11:06
问题 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

Spring managed transactions, EclipseLink JPA, custom isolation level

由 你。 提交于 2019-12-07 04:01:00
问题 I suspect this one is embarrassing an I am doing it wrong in a terrible way, but please bear with me. I have a Spring application with Spring-managed transactions. It uses EclipseLink JPA. I have a method which does a findByNativeQuery() followed by a merge() . I need this to happen in a real SERIAL transaction isolation level. I tried adding @Transactional(isolation=Isolation.SERIALIZABLE) This doesn't work because org.springframework.orm.jpa.vendor.EclipseLinkJpaDialect#beginTransaction

Glassfish: Unable to map datasource JNDI name to portable name using glassfish-web.xml

由 北城余情 提交于 2019-12-07 02:11:57
问题 I'm going slightly insane trying to make a Java EE 6 webapp portable between Glassfish AS 3.x and JBoss AS 6 (and 7 when released). Because each server maps JNDI names for datasources differently, I need to specify an application-private internal name for the datasource in persistence.xml then use glassfish-web.xml or jboss-web.xml (as appropriate) to map that to a real datasource name in the server. The theory is simple (well, for EE): Use internal name in persistence.xml, eg "my-datasource"

EclipseLink MOXy: Override rules of binding files

由 落爺英雄遲暮 提交于 2019-12-07 01:53:28
I would, in the scenario below, like the binding of java-type name="SubClass" to be applied to set the text field on SuperClass. However it is not. Is there a problem with overriding the bindingsA.xml? According to the Overriding rules documentation : If the same java-type occurs in multiple files, any values that are set in the later file, will override values from the previous file What do I need to do to make it work? Input: <?xml version="1.0" encoding="UTF-8"?> <a text="A text">B text</a> Bindings A: <?xml version="1.0"?> <xml-bindings xmlns="http://www.eclipse.org/eclipselink/xsds
