[Hibernate-JIRA] Created: (HHH-2222) SpringFramework 2.0 uses ASM.JAR versions 2.2.2. This is incompatible with Hibernate 3.2 as it uses and "unknown" previous version of ASM.JAR

by Greg McGregor (JIRA)

SpringFramework 2.0 uses ASM.JAR versions 2.2.2. This is incompatible with Hibernate 3.2 as it uses and "unknown" previous version of ASM.JAR ---------------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-2222 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2222 Project: Hibernate3 Type: Improvement Versions: 3.2.0.ga Environment: Hibernate 3.2.0ga Reporter: Greg McGregor SpringFramework 2.0 uses ASM.JAR from ObjectWeb version 2.2.2. However, Hibernate 3.2.0ga utilizes an "unknown" previous version of the ASM.JAR. The issue is that the method signatures and classes have changed between the two versions. Therefore, Hibernate 3.2.0ga won't run with the new ASM.JAR and Spring 2.0 won't run with the previous ASM.JAR. Mushing the two JARs together in an attempt to get something going results in a NoSuchMethodError (which would make sense). Although this isn't a direct Hibernate3 bug, it does preclude stable use with Spring 2.0/ -- 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-2159) Query that previously worked in 3.2.0CR2 does not work anymore

by Andy Dale (JIRA)

Query that previously worked in 3.2.0CR2 does not work anymore --------------------------------------------------------------- Key: HHH-2159 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2159 Project: Hibernate3 Type: Bug Versions: 3.2.0.ga Environment: hibernate 3.2.0GA, PostgreSQL 8.1.4 (using build 407 of the JDBC driver). JDK 1.5.0_06, JBoss 4.0.4GA, Operating system is Fedora Core 5 Reporter: Andy Dale Attachments: hibernate_testcase.tar.gz First off i do not know if this bug belongs to the Hibernate3(core) or Hibernate EntityManger branch, but have entered it against core because that is where the exception occurs (in org.hibernate.hql.ast.tree.FromClause.findIntendedAliasedFromElementBasedOnCrazyJPARequirements). I have a relativley simple entity setup up to test a proof of concept. Persisting the data to the database is not a problem in the new version 3.2.0.GA, but the problems occurs when trying to perform a query on the persisted data, the very same query works with 3.2.0CR2 but gives a nullPointException in 3.2.0GA. I have attached the java source for the entities + session bean (in hibernate_testcase.tar.gz/entities file) and the java class (in hibernate_testcase.tar.gz/service file) that is used to persist and query the data, and because this was only meant to be a proof of concept i have also included the .ear archive as apart from the entity definitions and session bean the only other thing it contains is a JBoss .sar archive which calls the static persist and query methods in the session bean (service test.testcase). Please note to use the .ear archive you need a datasource called Postgres_Test -- 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-2211) A createQuery() caused ORA-00904 error

by sodia (JIRA)

A createQuery() caused ORA-00904 error -------------------------------------- Key: HHH-2211 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2211 Project: Hibernate3 Type: Bug Components: query-hql Versions: 3.2.0.ga Environment: JDK1.5.0+Eclipse3.2.1+Hibernate3.2.0.ga+Oracle9.2.0+WinXp(Prof)Sp2 Reporter: sodia Priority: Trivial Attachments: hiber-grammar-sql-and-errlog.zip, hiber-grammar-test.zip I want to try the following sql under hibernate,it failed. (The project is build on the basis of hibernate3.2's tutorial) String hqlAlias = "insert into EventHistory ( id, date, title )" + " select id, date, title from Event e" + " where e.title like 'BUY%'" + " and exists" + " ( select 1 from PersonEvent p" + " where p.id=e.id)"; int resultAlias = session.createQuery(hqlAlias).executeUpdate(); But it works nice under sqlplus.

[Hibernate-JIRA] Created: (HHH-2110) Proxied object causes ClassCastException when method returns 'this' in a composite hierarchy

by Philip Nightingale (JIRA)

Proxied object causes ClassCastException when method returns 'this' in a composite hierarchy -------------------------------------------------------------------------------------------- Key: HHH-2110 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2110 Project: Hibernate3 Type: Bug Components: core Versions: 3.0.5 Environment: Hibernate 3, any database (test case uses HSQL, issue found using Oracle) Reporter: Philip Nightingale Attachments: HibernateClassCastExceptionTest.zip If a proxied object has a method that returns 'this' and the proxy type extends the same base class as the target object and the return type of the method is the target class type then a ClassCastException is thrown. The error can be tracked down to the method CGLibLazyInitializer::intercept(Object, Method, Object[], MethodProxy). In this method, if the object returned from the method call on the target object is the same as the target object, then instead of returning the object itself the proxy is returned. This is fine in most cases, but in the special case described, in which the proxy extends a base class that is also extended by the target class, then the CCE occurs. In the submitted test case I have a simple composite hierarchy with an abstract base type and two concrete subtypes. Either type can contain children, but only one can be the root of the hierarchy (and cannot itslef be a child). There is a many-to-one relationship defined from the sub-type that may be a child to the base class. The submitted test case is configured to use Hypersonic DB so hsqldb.jar is required on the classpath. Further details and code snippets from the original code that caused the exception are posted on the Hibernate user forum (topic "ClassCastException with CGLIB Lazy Initialization") -- 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: (EJB-255) Remoting capabilities

by Dimitry Voytenko (JIRA)

Remoting capabilities --------------------- Key: EJB-255 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-255 Project: Hibernate Entity Manager Type: New Feature Reporter: Dimitry Voytenko I came across Kodo's implementation of remote persistent managers for both JPA and JDO: http://www.solarmetric.com/Software/Documentation/3.2.0RC2/docs/ref_guide... http://www.solarmetric.com/Software/Documentation/3.2.0RC2/docs/ref_guide... The solution looks pretty ellegant. The main idea behind it is that server and client communicate b/w each other using object graphs (no proxies and no object serialization required) and thus working with JDO/JPA objects on client looks exactly the same as on the server, removing necessity of DTO objects in the majority of cases. Have you ever thought about including similar functionality for Hibernate? I do believe it could be a great peformance booster for many types of applications. -- 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-733) Updated DAO code generation as discussed over the email

by Alex Kalinovsky (JIRA)

Updated DAO code generation as discussed over the email ------------------------------------------------------- Key: HBX-733 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-733 Project: Hibernate Tools Type: Patch Components: hbm2java, ant Versions: 3.1alpha5 Environment: I have tested the patch on the latest version of Hibernate Tools I got from SVN 2 weeks ago. Reporter: Alex Kalinovsky Attachments: dao_generation.patch This should be a complete implementation of DAO generation according to the design we have discussed over the email. I've tested this on our project so the DAOs should be good to go, but of course a more diverse testing would be needed before releasing it to public. I'm open for recommendations and suggestions, so I see this as the first draft. Below is a list of files and comments. Contact me at kalinovsky(a)yahoo.com. src/java/org/hibernate/tool/hbm2x DAONewExporter.java This class is coded mainly to accept additional parameters such as dao package name and provide flexible file naming that is used by Ant task.
