[Hibernate-JIRA] Created: (JPA-15) Criteria API based on MapKeyColumn is not working

by Edwin Dalorzo (JIRA)

Criteria API based on MapKeyColumn is not working ------------------------------------------------- Key: JPA-15 URL: http://opensource.atlassian.com/projects/hibernate/browse/JPA-15 Project: Java Persistence API Issue Type: Bug Environment: Hibernate 3.6.1 MySQL 5.0 Reporter: Edwin Dalorzo Attachments: log.txt, src.zip I defined an Employee entity having a map of phone numbers, where the key is the type of phone (home, office, mobile) and the value is the phone number as a String. @ElementCollection(fetch=FetchType.LAZY) @CollectionTable(name="emp_phone") @MapKeyColumn(name="phone_type") @Column(name="phone_num") private Map<String, String> phoneNumbers; Then I tried to write a Criteria API query using a map join, like this: CriteriaBuilder builder = entityManager.getCriteriaBuilder(); CriteriaQuery<Employee> criteria = builder.createQuery(Employee.class); Root<Employee> employeeRoot = criteria.from(Employee.class); criteria.select(employeeRoot); MapJoin<Employee, String, String> phoneRoot = employeeRoot.joinMap("phoneNumbers"); criteria.where(builder.equal(phoneRoot.key(), "HOME")); System.out.println(entityManager.createQuery(criteria).getResultList()); You get an NullPointerException java.lang.NullPointerException at org.hibernate.ejb.criteria.path.AbstractPathImpl.prepareAlias(AbstractPathImpl.java:246) at org.hibernate.ejb.criteria.path.AbstractPathImpl.render(AbstractPathImpl.java:253) at org.hibernate.ejb.criteria.predicate.ComparisonPredicate.render(ComparisonPredicate.java:173) at org.hibernate.ejb.criteria.QueryStructure.render(QueryStructure.java:258) at org.hibernate.ejb.criteria.CriteriaQueryImpl.render(CriteriaQueryImpl.java:340) at org.hibernate.ejb.criteria.CriteriaQueryCompiler.compile(CriteriaQueryCompiler.java:223) at org.hibernate.ejb.AbstractEntityManagerImpl.createQuery(AbstractEntityManagerImpl.java:441) at com.dalorzo.Main.main(Main.java:57) Exception in thread "main" java.lang.RuntimeException: java.lang.NullPointerException at com.dalorzo.Main.main(Main.java:64) Caused by: java.lang.NullPointerException at org.hibernate.ejb.criteria.path.AbstractPathImpl.prepareAlias(AbstractPathImpl.java:246) at org.hibernate.ejb.criteria.path.AbstractPathImpl.render(AbstractPathImpl.java:253) at org.hibernate.ejb.criteria.predicate.ComparisonPredicate.render(ComparisonPredicate.java:173) at org.hibernate.ejb.criteria.QueryStructure.render(QueryStructure.java:258) at org.hibernate.ejb.criteria.CriteriaQueryImpl.render(CriteriaQueryImpl.java:340) at org.hibernate.ejb.criteria.CriteriaQueryCompiler.compile(CriteriaQueryCompiler.java:223) at org.hibernate.ejb.AbstractEntityManagerImpl.createQuery(AbstractEntityManagerImpl.java:441) at com.dalorzo.Main.main(Main.java:57) If you change the query to filter on value instead of key, it works just fine criteria.where(builder.equal(phoneRoot.value(), "88750372")); I have attached a log with exceptions as well as the Employee entity and the Main class containing a main method. Also, the code in question runs perfectly fine in EclipseLink. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-6608) @JoinColumns doesn't work inside an @Embedded member

by Joeri Hendrickx (JIRA)

@JoinColumns doesn't work inside an @Embedded member ---------------------------------------------------- Key: HHH-6608 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6608 Project: Hibernate Core Issue Type: Bug Components: annotations, metamodel Affects Versions: 4.0.0.CR1, 3.5.6 Environment: Version 3.5.6 and up, no DB Reporter: Joeri Hendrickx Attachments: hibernate-embedded-joincolumns.zip If you use multiple joincolumns on a @ManyToOne or @OneToOne field in an @Embedded class, hibernate will fail when building its metamodel with the following exception: Exception in thread "main" org.hibernate.MappingException: property [_model_MainEntity_embeddedEntity.referencedEntity] not found on entity [model.ReferencedEntity] at org.hibernate.mapping.PersistentClass.getRecursiveProperty(PersistentClass.java:379) at org.hibernate.cfg.annotations.TableBinder.bindFk(TableBinder.java:406) at org.hibernate.cfg.ToOneFkSecondPass.doSecondPass(ToOneFkSecondPass.java:111) at org.hibernate.cfg.AnnotationConfiguration.processEndOfQueue(AnnotationConfiguration.java:541) at org.hibernate.cfg.AnnotationConfiguration.processFkSecondPassInOrder(AnnotationConfiguration.java:523) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:380) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1377) at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:954) at model.Test.main(Test.java:12) Caused by: org.hibernate.MappingException: property [_model_MainEntity_embeddedEntity.referencedEntity] not found on entity [model.ReferencedEntity] at org.hibernate.mapping.PersistentClass.getRecursiveProperty(PersistentClass.java:425) at org.hibernate.mapping.PersistentClass.getRecursiveProperty(PersistentClass.java:376) ... 8 more A test case is included. Just run model. Test with the hibernate libraries in the classpath. I get the impression this is because of the dot in the generated property name. Hibernate generates a synthetic property, named after the FQN of the owning entity (with dots replaces by underscores) appended by and underscore and the name of the property. But properties inside of embedded objects are represented with a dot; when Hibernate later tries to retrieve the same property, it incorrectly interprets this dot as a delimiter, and will look for `_model_MainEntity_embeddedEntity` (in the example above) instead; which it will not find. -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-2808) CLONE -Impossible to define caching for a subclass's collection in hibernate.cgf.xml

by Sebastien Blind (JIRA)

CLONE -Impossible to define caching for a subclass's collection in hibernate.cgf.xml ------------------------------------------------------------------------------------- Key: HHH-2808 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2808 Project: Hibernate3 Issue Type: Bug Components: caching (L2) Affects Versions: 3.2.5 Environment: Hibernate 3.2.5 Sybase Reporter: Sebastien Blind Basically, hibernate allows to define <cache usage="transactional"/> inside the subclass mapping, i.e. <subclass name="SubClass" extends="BaseClass" discriminator-value="xxx"> <bag name="subClassLinks" lazy="false" inverse="true" batch-size="100"> <cache usage="transactional" region="xxx"/> <key column="xxx" not-null="true"/> <one-to-many class="xxx"/> </bag> <join table="xxx"> </join> </subclass> but it's not allowed to do the same using <collection-cache collection="subClass.myCollection" region="xxx" usage="transactional"/>.

[Hibernate-JIRA] Created: (HHH-4959) Concurrent HQL parsing blocks on ReflectHelper.classForName()

by Jarl Totland (JIRA)

Concurrent HQL parsing blocks on ReflectHelper.classForName() ------------------------------------------------------------- Key: HHH-4959 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4959 Project: Hibernate Core Issue Type: Improvement Components: query-hql Affects Versions: 3.3.2 Environment: DB2 Reporter: Jarl Totland Priority: Minor Attachments: ReflectHelper.java For particularly HQL-heavy applications, concurrency is lost as ReflectHelper.classForName() blithely runs loadClass() for tokens again and again, many of which are not even classes. As loadClass() is synchronized it end up blocking while it generates stacktraces for its exceptions. This goes for both classic and AST parsers. Because of this blocking our regression tests took over 20 minutes, regardless of number of threads. Implementing a simple cache from String to Class in ReflectHelper.classForName() reduced this to 3 minutes for eight threads on a dual-core cpu; the bottleneck is now the database as it should be, not lock contention. The issue was reported earlier in HHH-1810, but dismissed as related to the classic parser only. We might use HQL in inappropriate ways, but still wouldn't hurt for Hibernate to support this. Attached is our modified ReflectHelper; modified code is in the classForName()-methods, classForNameInternal(), and the static HashMap<String, Object> classes. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-5274) HQL-Insert with Select and Sub-Select fails

by Björn Moritz (JIRA)

HQL-Insert with Select and Sub-Select fails ------------------------------------------- Key: HHH-5274 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5274 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.2 Environment: Hibernate 3.5.2, Oracle 10 (using org.hibernate.dialect.Oracle10gDialect) Reporter: Björn Moritz Attachments: Testcase.zip In Hibernate 3.5.2 a HQL-Insert statement doing a select using a subselect is failing. This is due to a wrong replacement of the table name in the generated SQL-Statement. The following statement will work: {code:sql}select a.id from A a where exists (select 1 from B b where b.id = a.id){code} but an insert statement embedding the same statement does not work: {code:sql}insert into C (id) select a.id from A a where exists (select 1 from B b where b.id = a.id){code} The latter statement will thrown an SqlSyntaxErrorException as the second 'a.id' will get replaced with 'AAA.id' (which is the real table name and not the alias used in the generated sql statement). In Hibernate 3.1.3 both statements worked fine. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
