[Hibernate-JIRA] Created: (HBX-1086) Support SpringJPAConfiguration

by John Turner (JIRA)

Support SpringJPAConfiguration ------------------------------ Key: HBX-1086 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1086 Project: Hibernate Tools Issue Type: New Feature Components: ant Affects Versions: 3.2.0.GA Reporter: John Turner I'm working on a module based approach to developing a persistence layer for a web application. One of the things I want to be able to do is deploy each module in its own jar file with a corresponding persistence.xml file. Having done this spring's PersistenceUnitManager detects the persistence.xml files at runtime and merges the persistence configuration files into a single persistence configuration. Problem is, at build time, I use hibernate tools and jpa configuration to build drop and create schema ddl. This just picks up the first persistence.xml on the classpath and uses it to provide the jpa configuration. I would like to see a SpringJPAConfiguration that operates in the same way as the PersistenceUnitManager. -- 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-2592) force hibernate to generate use offset qeury when offset is zero

force hibernate to generate use offset qeury when offset is zero ---------------------------------------------------------------- Key: HHH-2592 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2592 Project: Hibernate3 Issue Type: Improvement Components: query-criteria, query-hql, query-sql Affects Versions: 3.2.3 Environment: Hibernate Core 3.2.3 + Hibernate Annotations 3.3.0 JDK 5.0 Oracle 10g r2 Reporter: Amir Pashazadeh Attachments: patch.zip I know this is mostly an Oracle issue, but believe me it is harder to fix it in Oracle! when the offset of a paged query is zero, Hibernate does not append offset part to query, but the result which is returned by oracle without the offset part, and result returned when offset is zero is different. so some records are retrieved in different pages, and some records (which must be in first page) are not retrieved at all. ---- the patch is included.

[Hibernate-JIRA] Created: (HHH-3450) Include SingletonEhCacheProvider as an additional caching provider

by Greg Luck (JIRA)

Include SingletonEhCacheProvider as an additional caching provider ------------------------------------------------------------------ Key: HHH-3450 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3450 Project: Hibernate3 Issue Type: Improvement Components: caching (L2) Affects Versions: 3.3.0.GA Environment: Any Reporter: Greg Luck Attachments: SingletonEhCacheProvider.java The SingletonEhCacheProvider complements the existing EhCacheProvider in that it is a singleton. This matches the way the provider used to work in older versions of Hibernate/Ehcache. It is preferable to use the SingletonEhCacheProvider unless a user is running multiple versions of Hibernate (a use case we had at wotif) or multiple instances of SessionFactory. This provider is distributed with Ehcache but not with Hibernate. It would be preferable it we added it to Hibernate and it is frequently overlooked by users. This code is in production use on many systems, including those of the author. The attached class is the one from the Ehcache project. It will need some minor tweaking to match the conventions of Hibernate project. -- 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-3392) Query Cache entries are not distributable

On 14/06/2008, at 2:40 PM, Steve Ebersole wrote: Considering that RootEntityResultTransformer is not performing an kind of data uniqueing (singleton, etc) then yes that would be an issue. There is nothing wrong with caching a query which uses a ResultTransformer per-se. As simple test would be to add an equals() override to RootEntityResultTransformer where the class of the operands are evaluated: public boolean equals(Object other) { // all RootEntityResultTransformers are considered equal return other != null && RootEntityResultTransformer.class.isInstance( other ) } On Tue, 2008-06-10 at 14:35 +1000, Greg Luck wrote: Steve I have a question from a Hibernate/Ehcache user. When he replicates a cached Query it does not get hit on the second box.

How does this work for any distributed cache? Begin forwarded message: From: alvins <alvins1982(a)hotmail.com> Date: 9 June 2008 9:26:38 PM To: ehcache-list(a)lists.sourceforge.net Subject: [ehcache-list] Distributed ehcache - queries I am having some problems with ehcache in distributed mode and queries. I have a simple spring+hibernate+ehcache webapp running on two tomcat servers. I have enabled second level caching and I can see my simple pojo gets replicated back and forth fine between the two servers. The query caching seems to work fine if I have a single server started. I can see that is using the cached query and not hitting the db. However what I am trying to test is if I have two boxes - box1 does query and populates cache which gets replicated to box2 - then box2 doesn't need to do query since its in cache. My problem is that the query from box1 is not recognized as being the same as on box2 - it seems to get cached multiple times. Below is a log snippet of the two objects which are in my query cache - there should only be one. The first debug line is showing a query object which was replicated over from another box - the second line is showing a query object which was populated locally. This should not happen since they are the same query. 21:03:39,763 DEBUG net.sf.ehcache.store.MemoryStore - findTopXCache: findTopXMemoryStore hit for sql: select this_.emp_id as emp1_2_0_, this_.emp_firstname as emp2_2_0_, this_.emp_surname as emp3_2_0_ from Employee this_; parameters: ; first row: 0; max rows: 10; transformer: org.hibernate.transform.RootEntityResultTransformer@a725aa LOCAL: [ key = sql: select this_.emp_id as emp1_2_0_, this_.emp_firstname as emp2_2_0_, this_.emp_surname as emp3_2_0_ from Employee this_; parameters: ; first row: 0; max rows: 10; transformer: org.hibernate.transform.RootEntityResultTransformer@a725aa, value=[4968486262001664, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10], version=1, hitCount=0, CreationTime = 1213009341528, LastAccessTime = 0 ] 21:03:39,763 DEBUG net.sf.ehcache.store.MemoryStore - findTopXCache: findTopXMemoryStore hit for sql: select this_.emp_id as emp1_2_0_, this_.emp_firstname as emp2_2_0_, this_.emp_surname as emp3_2_0_ from Employee this_; parameters: ; first row: 0; max rows: 10; transformer: org.hibernate.transform.RootEntityResultTransformer@aa11a6 LOCAL: [ key = sql: select this_.emp_id as emp1_2_0_, this_.emp_firstname as emp2_2_0_, this_.emp_surname as emp3_2_0_ from Employee this_; parameters: ; first row: 0; max rows: 10; transformer: org.hibernate.transform.RootEntityResultTransformer@aa11a6, value=[4968486194896896, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10], version=1, hitCount=5, CreationTime = 1213009325003, LastAccessTime = 1213009415332 ] Does anybody have any ideas? -- View this message in context: http://www.nabble.com/Distributed-ehcache---queries-tp17730904p17730904.html Sent from the Ehcache mailing list archive at Nabble.com. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
