[Hibernate-JIRA] Created: (ANN-527) reference a target entity (in a collection) by entity name

by Armin Haaf (JIRA)

reference a target entity (in a collection) by entity name ---------------------------------------------------------- Key: ANN-527 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-527 Project: Hibernate Annotations Type: New Feature Components: binder Reporter: Armin Haaf It is only possible to reference a targetEntity by class. @ManyToMany(targetEntity = TestImpl.class) List<Test> myList; This makes it impossible to exchange TestImpl.class implemention by another implemention by the mappings definition. It would be helpful to reference a targetEntity by name. @ManyToMany(targetEntityName = "Test") This would help a lot to implement moduls and frameworks. Another way to support this would be to search for a implementation of the collection elements (which are typically Interfaces) in the mapped entities -- 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

HSQL DB + multi-schema --> raised an exception (Problem to get an increment key [select max(id) from table) ----------------------------------------------------------------------------------------------------------- Key: HHH-2066 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2066 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr4 Environment: HSQL DB 1.8.x Reporter: XOrangOutan When trying to save an object that has an "incremental" primary key, Hibernate API tries to know what the max current id is by executing a "SELECT MAX". Though, in this particular sql query, schema name is not taken into account (in hsqldialect). This cause an error that prevents anyone from carrying out unit tests.

[Hibernate-JIRA] Created: (HHH-2281) CLONE -Calling Session.connection() generates java.lang.IllegalArgumentException: interface org.hibernate.jdbc.ConnectionWrapper is not visible from class loader

by Sergey Polzunov (JIRA)

CLONE -Calling Session.connection() generates java.lang.IllegalArgumentException: interface org.hibernate.jdbc.ConnectionWrapper is not visible from class loader ----------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-2281 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2281 Project: Hibernate3 Type: Bug Versions: 3.2.1 Environment: Hibernate checked out from trunk; revision 10717 Reporter: Sergey Polzunov Calling Session.connection() always generates an exception. Here is the stacktrace I get from the attached test case: Exception in thread "main" java.lang.IllegalArgumentException: interface org.hibernate.jdbc.ConnectionWrapper is not visible from class loader at java.lang.reflect.Proxy.getProxyClass(Proxy.java:353) at java.lang.reflect.Proxy.newProxyInstance(Proxy.java:581) at org.hibernate.jdbc.BorrowedConnectionProxy.generateProxy(BorrowedConnectionProxy.java:56) at org.hibernate.jdbc.ConnectionManager.borrowConnection(ConnectionManager.java:163) at org.hibernate.jdbc.JDBCContext.borrowConnection(JDBCContext.java:111) at org.hibernate.impl.SessionImpl.connection(SessionImpl.java:359) at TestSession.main(TestSession.java:16) Changing the Connection.class.getClassLoader() to BorrowedConnectionProxy.class.getClassLoader() on line 57 in the generateProxy() method solves the problem. I am not very familiar with class loaders so I don't know if this is likeley to cause other problems elsewhere. Removing the ConnectionWrapper.class from the PROXY_INTERFACES array in the org.hibernate.jdbc.BorrowedConnectionProxy also solves the problem, but I guess it was added for a reason. -- 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

by Hernan Liendo (JIRA)

A query validation bug produces QueryException: "Expected positional parameter count: 1, actual parameters: [Parent@bec357b] [from Child this where this.id.parent = ?]" ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Key: HHH-2254 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2254 Project: Hibernate3 Type: Bug Components: query-hql Versions: 3.2.0.ga Environment: Hibernate 3.2 using Sybase. However this is not an environment caused problem. It's supposed to happen in every environment. Reporter: Hernan Liendo -- Short description ============================================================================ -- A query validation bug produces QueryException: "Expected positional parameter count: 1, actual parameters: [Parent@bec357b] [from Child this where this.id.parent = ?].

It resolves the "positionalValueSpan" variable witch in my case gets the value of 2 (One for parent's idField1 and the other for parent's idField2). The method compares positionalValueSpan (2) with parameterMetadata.getOrdinalParameterCount() witch it is 1 (the quantity of "?" signs in the HQL statement". This bug only happens when: 1. composed keys are used (and) 2. having a parent-child relationship (and) 3. resolving children from certain parent. -- Hibernate user workaround ============================================================================ -- Not to use a parent instance variable in the Child class. Hope this helps. If you guys need the source code in order to check the bug, please let me know it. Good luck!

[Hibernate-JIRA] Created: (HHH-2153) Not possible to overwrite System property defaults with hibernate.properties (e.g. use cglib bytecode provider in jboss)

by Armin Haaf (JIRA)

Not possible to overwrite System property defaults with hibernate.properties (e.g. use cglib bytecode provider in jboss) ------------------------------------------------------------------------------------------------------------------------ Key: HHH-2153 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2153 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.ga Environment: JBoss 4.0.4GA, hibernate 3.2.0.ga Reporter: Armin Haaf It is not possible to set the bytecode provider by hibernate.properties, because jboss ejb3.deployer sets it in System.properties. System.properties is added to the GLOBAL_PROPERTIES in Environment.class after hibernate.properties and overwrites the values in hibernate.properties. A solution would be to change the order of adding the properties to GLOBAL_PROPERTIES. First add System.properties, then add hibernate.properties, to be able to overwrite as needed -- 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
