[Hibernate-JIRA] Created: (HHH-2442) ClassCastException loading from second level cache

by Marcio Moraes (JIRA)

ClassCastException loading from second level cache -------------------------------------------------- Key: HHH-2442 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2442 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.1, 3.2.2, 3.2.0.ga Environment: Linux 2.6.15-27-686 #1 SMP PREEMPT Fri Dec 8 18:00:07 UTC 2006 i686 GNU/Linux Reporter: Marcio Moraes Priority: Blocker I'm getting a error when using hibernate 3.2.2.ga with cache (JBoss-Cache) cluster. When hibernate get a entity from second level cache it confuses the arrays of values against array of types. So in some situations i got ClassCastException ... Looking up CacheEntry code at assemble method i saw: private static Object[] assemble( final Serializable[] values, final Object result, final Serializable id, final EntityPersister persister, final Interceptor interceptor, final EventSource session) throws HibernateException { //assembled state gets put in a new array (we read from cache by value!) Object[] assembledProps = TypeFactory.assemble( values, persister.getPropertyTypes(), session, result ); The issue is values (Serializeble[]) is in wrong order compared with persister.getPropertyTypes() (Type[]). If only one cache instance is running it doesnt occurs ... I am using Linux.

[Hibernate-JIRA] Created: (HHH-3247) Provide more information in TypeMismatchException message

by Szczepan Kuzniarz (JIRA)

Provide more information in TypeMismatchException message --------------------------------------------------------- Key: HHH-3247 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3247 Project: Hibernate3 Issue Type: Improvement Components: core Affects Versions: 3.2.6 Reporter: Szczepan Kuzniarz When DefaultLoadEventListener throws TypeMismatchException it provides information about expected and actual id types: "Provided id of the wrong type. Expected: " + idClass + ", got " + event.getEntityId().getClass() but it says nothing about the offending class. It is not always the class which is loaded by client (it may be one of associated classes) and sometimes it's not easy to track it down. It would be nice if DefaultLoadEventListener would report something like this: "Provided id of the wrong type for class " + persister.getEntityName() + ". Expected: " + idClass + ", got " + event.getEntityId().getClass() -- 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
