[Hibernate-JIRA] Created: (HHH-3333) build Documentation has a typo and includes a lie re:jdk version

by Andrew C. Oliver (JIRA)

build Documentation has a typo and includes a lie re:jdk version ---------------------------------------------------------------- Key: HHH-3333 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3333 Project: Hibernate3 Issue Type: Bug Components: build, documentation Affects Versions: 3.2.4.sp1 Reporter: Andrew C. Oliver Priority: Minor See here: http://hibernate.org/6.html#A6 "Compiling Hibernate Run build.xml with Ant under JDK 1.2 or later (JKD 1.4 required" Should be JDK 1.4 required However actually "or later" is an error http://opensource.atlassian.com/projects/hibernate/browse/HHH-2446 as JDK 6+ cannot be used to build. "You need to use JDK 5.0 or later" is said for Hibernate Annotations, but I cannot evaluate the statement by itself nor would it likely be very fun to have H3 compiled into JDK5 classes and H3A in JDK6... It should be corrected to prevent lots of duplicate JIRA bugs saying "I followed the instructions but H3 doesn't compile!" -- 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-3285) Cast function invoking another function with two arguments.

by Pedro Gonçalves (JIRA)

Cast function invoking another function with two arguments. ----------------------------------------------------------- Key: HHH-3285 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3285 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.6 Environment: 3.2.6, Oracle 9i Reporter: Pedro Gonçalves Hi. I think that i found a bug. In my hql, in select clause if i put something like this: "select cast(myfunction(table.field1,anotherfunction(table.field2)) as string) ) as myresult, table.field1, table.field2 from MyClass " i have this error: Caused by: org.hibernate.QueryException: cast() requires two arguments ... I think that the second comma after field1 is making hibernate crazy, because when i try another function like this: "select cast(myfunction(table.field) as string) ) as myresult, table.field1, table.field2 from MyClass " everything works fine. Thanks! -- 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: (HBX-974) Unable to recreate tables using Hibernate

by sridhar negi (JIRA)

Unable to recreate tables using Hibernate ------------------------------------------ Key: HBX-974 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-974 Project: Hibernate Tools Issue Type: Task Environment: Oracle 9i. Reporter: sridhar negi i m using SchemaUpdate tool of Hibernate.The problem which i m facing is that i had some tables in the database ,now i needed to delete some of the columns from some of the tables. Since UpdateSchema does not allow to delete columns ,i decided to manually drop the those tables from oracle database and recreate those tables. But i m not able to do the same. It tries to fire alter table command, even when there is no such table present in the database..The error whcih i m getting is some thing like this.. [java] alter table POOL_DETAILS add POOL_WEIGHT DOUBLE PRECISION [java] 52085 DEBUG [main] hbm2ddl.SchemaUpdate - execute alter table POOL_DETAILS add POOL_WEIGHT DOUBLE PRECISION [java] 52147 ERROR [main] hbm2ddl.SchemaUpdate - execute Unsuccessful: alter table POOL_DETAILS add POOL_WEIGHT DOUBLE PRECISION [java] 52147 ERROR [main] hbm2ddl.SchemaUpdate - execute ORA-00942: table or view does not exist -- 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: (HBX-954) Failing detection of Sequences?

by Vincent Latombe (JIRA)

Failing detection of Sequences? ------------------------------- Key: HBX-954 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-954 Project: Hibernate Tools Issue Type: Bug Environment: Hibernate3 as provided by Seam 1.2.1GA (dunno which subversion) Oracle 10g Reporter: Vincent Latombe Here is my problem : I used reverse engineering to get an entity from a table in a database. I got my entity then I wanted to add a generation for the Id. Fine, I add HIBERNATE_SEQUENCE which is needed then I add the annotation to my entity. I get this : @Id @Column(name = "ID", precision = 22, scale = 0) @GeneratedValue(strategy=GenerationType.SEQUENCE) @NotNull public long getId() { return this.id; } Nothing really difficult. Then I try to deploy my ejb using the validate strategy of hbm2ddl. And it fails because it can't find the sequence ([DatabaseMetadata] table not found: TESTSEAM.hibernate_sequence)... Ok strange. Then I switch to the update strategy... Now I get something interesting. 14:40:12,843 INFO [DatabaseMetadata] table not found: TESTSEAM.hibernate_sequence 14:40:12,843 INFO [DatabaseMetadata] table not found: hibernate_sequence 14:40:12,875 ERROR [SchemaUpdate] Unsuccessful: create sequence TESTSEAM.hibernate_sequence 14:40:12,875 ERROR [SchemaUpdate] ORA-00955: ce nom d'objet existe dÚjÓ 14:40:12,875 INFO [SchemaUpdate] schema update complete It seems that DatabaseMetadata try to lookup a table instead of a sequence, so it can't detect the already existing sequence. So then it tries to create the sequence but it already exists. Any clue? -- 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-3293) Event System is poorly document

by Alberto A. Flores (JIRA)

Event System is poorly document ------------------------------- Key: HHH-3293 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3293 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.6 Reporter: Alberto A. Flores In reading interceptor vs. event listeners, it appears that documentation on "event systems" is very poor. Further more, there is no documentation as to how and when evenlisteners are called (which can be relevant depending on the constraints specified in the hbm file and/or db schema. I encountered a problem where the PreInsertEventListener is not only poorly documented in the javadoc (see HHH-1942 and HHH-3237) but also, the DefaultSaveOrUpdateEventListener is ran first after which the Nullability engine checks for constraints in the hbm file and *then* the defined PreInsertEventListener code is executed. This had to be learned by painful debugging when clear documentation could avoid this. The intent was to run the PreInsertEventListener to avoid the not-null constraint, but obviously this is not possible with the current design. -- 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-2958) Incomplete/non-informative javadocs for events system

by Jacob L E Blain Christen (JIRA)

Incomplete/non-informative javadocs for events system ----------------------------------------------------- Key: HHH-2958 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2958 Project: Hibernate3 Issue Type: Task Components: documentation Affects Versions: 3.2.5, 3.2.4.sp1, 3.2.4, 3.2.3, 3.2.2, 3.2.1, 3.2.0.ga, 3.2.0.cr5, 3.2.0.cr4, 3.2.0.cr3, 3.2.0.cr2, 3.2.0 cr1, 3.1.3, 3.2.0.alpha2, 3.2.0.alpha1, 3.1.2, 3.1.1, 3.1, 3.1 rc3, 3.1 rc2, 3.1 rc 1, 3.1 beta 2, 3.1 beta 1, 3.0.5 Reporter: Jacob L E Blain Christen Priority: Minor See also HHH-1942. As per the documentation at http://www.hibernate.org/hib_docs/v3/api/org/hibernate/event/PreUpdateEve... (as an example) and HHH-1942 I most definately do not consider <pre><code>org.hibernate.event Interface PreUpdateEventListener All Superinterfaces: Serializable All Known Implementing Classes: JACCPreUpdateEventListener public interface PreUpdateEventListener extends Serializable Called before updating the datastore Author: Gavin King Method Summary boolean onPreUpdate(PreUpdateEvent event) Method Detail onPreUpdate public boolean onPreUpdate(PreUpdateEvent event)</code></pre> to be "documented" in any meaningful sense. It would be terrific if the event system javadocs as a whole were on par with the quality of the core hibernate javadocs. -- 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-2463) ClassCastException when Hibernate tries to cache results using ResultTransformer

by Peak user (JIRA)

ClassCastException when Hibernate tries to cache results using ResultTransformer -------------------------------------------------------------------------------- Key: HHH-2463 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2463 Project: Hibernate3 Type: Bug Versions: 3.2.2 Reporter: Peak user When Hibernate executes a cacheable query using a ResultTransformer, it will attempt to cache the results AFTER applying the ResultTransformer. The problem is that the ResultTransformer may modify the data in a way that Hibernate won't understand it anymore, and in this case it will generate a ClassCastException when trying to cache it. This problem could be easily solved if Hibernate cached results before applying the ResultTransformer instead of afterwards. Here's a sample code to reproduce this problem: class ToMapResultTransformer implements ResultTransformer { private String[] properties; public ToMapResultTransformer(String[] properties) { this.properties = properties; } public List transformList(List collection) { return collection; } public Object transformTuple(Object[] tuple, String[] aliases) { Map<String,Object> result = new HashMap<String,Object>(tuple.length); for (int i=0; i<tuple.length; i++) { result.put((properties != null ? properties[i] : aliases[i]), tuple[i]); } return result; } } Criteria sqlCriteria = createSqlCriteria(session); sqlCriteria.setProjection(projections); sqlCriteria.setCacheable(true); sqlCriteria.setResultTransformer(new ToMapResultTransformer(properties)); sqlCriteria.list(); The code above produces the following exception: java.lang.ClassCastException: java.util.HashMap at org.hibernate.cache.StandardQueryCache.put(StandardQueryCache.java:83) at org.hibernate.loader.Loader.putResultInQueryCache(Loader.java:2185) at org.hibernate.loader.Loader.listUsingQueryCache(Loader.java:2129) at org.hibernate.loader.Loader.list(Loader.java:2087) at org.hibernate.loader.criteria.CriteriaLoader.list(CriteriaLoader.java:94) at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1569) at org.hibernate.impl.CriteriaImpl.list(CriteriaImpl.java:283) -- 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-2525) Bug when using a ResultTransformer on a cached query

by Sebastien Cesbron (JIRA)

Bug when using a ResultTransformer on a cached query ---------------------------------------------------- Key: HHH-2525 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2525 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.2 Environment: Firebird 2.0 on Win XP Reporter: Sebastien Cesbron Attachments: testhib.zip Using a distinct result transformer which a cached like this : query = session.createQuery("select obj from ObjetTest obj left outer join fetch obj.children as obj_0 order by obj.id asc"); query.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY); query.setCacheable(true); query.list(); This leads to this exception 2007-03-21 14:28:20,589 ERROR : IllegalArgumentException in class: ObjetTest, getter method of property: oid Exception in thread "main" org.hibernate.PropertyAccessException: IllegalArgumentException occurred calling getter of ObjetTest.oid at org.hibernate.property.BasicPropertyAccessor$BasicGetter.get(BasicPropertyAccessor.java:171) at org.hibernate.tuple.entity.AbstractEntityTuplizer.getIdentifier(AbstractEntityTuplizer.java:183) at org.hibernate.persister.entity.AbstractEntityPersister.getIdentifier(AbstractEntityPersister.java:3524) at org.hibernate.persister.entity.AbstractEntityPersister.isTransient(AbstractEntityPersister.java:3240) at org.hibernate.engine.ForeignKeys.isTransient(ForeignKeys.java:181) at org.hibernate.engine.ForeignKeys.getEntityIdentifierIfNotUnsaved(ForeignKeys.java:218) at org.hibernate.type.ManyToOneType.disassemble(ManyToOneType.java:163) at org.hibernate.cache.StandardQueryCache.put(StandardQueryCache.java:80) at org.hibernate.loader.Loader.putResultInQueryCache(Loader.java:2118) at org.hibernate.loader.Loader.listUsingQueryCache(Loader.java:2062) at org.hibernate.loader.Loader.list(Loader.java:2020) at org.hibernate.loader.hql.QueryLoader.list(QueryLoader.java:393) at org.hibernate.hql.ast.QueryTranslatorImpl.list(QueryTranslatorImpl.java:338) at org.hibernate.engine.query.HQLQueryPlan.performList(HQLQueryPlan.java:172) at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1121) at org.hibernate.impl.QueryImpl.list(QueryImpl.java:79) at Test.main(Test.java:33) Caused by: java.lang.IllegalArgumentException: object is not an instance of declaring class at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.hibernate.property.BasicPropertyAccessor$BasicGetter.get(BasicPropertyAccessor.java:145) ... 16 more It seems this is due to a difference in QueryLoader.getResultColumnOrRow. In this method there is a test : else if ( !hasTransform ) { return row.length == 1 ? row[0] : row; } This causes the method to return an instance of ObjetTest in one case and an instance of ObjetTest[1] in the other one.
