[Hibernate-issues] [Hibernate-JIRA] Closed: (HB-214) Deadlock in processing "composite-id -> key-many-to-one"

[<leg...@at...>]

Message:

   The following issue has been closed.

   Resolver: Gavin King
       Date: Tue, 29 Jul 2003 8:36 PM

As per the documentation and FAQ, classes with embedded composite ids must implement equals()/hashCode().

Also, I changed to unsaved-value="any", for your example code.

Description:
I want use multi-primary-key and foriegn-key as primary-key in my project. The insert and update operator can work correctly, but the load operator can not work correctly. After tracing the source code of hibernate, I think problem is the process of the <composition-id> with <key-many-to-one> element. 
I can not sure it is a bug or hibernate can not support my database schema. What can I do?

My Sample is: 
-----------------------DataBase Schema---------------------------------

Description:

Is it legal to map a many-to-one class to an interface. I have done this with
the father property (in the attached example), however, I am receiving errors when I try to load records where
the parent property is not null.

I have attached a set of files that demonstrate the error I am getting.  To use:
1. run the sql script to build files and populate data
   Note: I'm using MySQL so you might have to change for a different DB
2. Change eg.test configuration properites to reflect your DB setup
3. Run eg.test
   Everything should work fine and "Detail B1 - F3" should be printed
   to the output
4. Now in eg.test, change the configuration to use eg.IFather instead of eg.Father
5. In IDetail, change the m-1 father property from eg.Father to eg.IFather
6. Re-run and you will get this error.

Exception in thread "main" java.lang.IllegalArgumentException: No visible constructors in interface eg.IFather

[Hibernate-issues] [Hibernate-JIRA] Closed: (HB-217) Criteria ignores discriminator, instantiates with wrong class

[<leg...@at...>]

Message:

   The following issue has been closed.

   Resolver: Gavin King

This was already fixed in CVS.

---------------------------------------------------------------------
        Key: HB-217
    Summary: Criteria ignores discriminator, instantiates with wrong class
       Type: Bug

     Status: Closed
   Priority: Major
 Resolution: DUPLICATE

    Project: Hibernate2
   Versions:
             2.0.2

   Assignee: 
   Reporter: Anders Bengtsson

    Created: Mon, 28 Jul 2003 11:19 AM
    Updated: Tue, 29 Jul 2003 8:33 PM

Description:
When searching in a subclass with a Criteria, *all* rows in the table are returned, not only those belonging to the subclass.

Example: Base class A, with subclasses B and C. Using session.createSearch(B.class).list() will incorrectly return all rows of both B and C, all of them instantiated as B's.

Searching for A works, both B's and C's get instantiated the right way. It is only when searching for a subclass it seems to ignore the discriminator field.

The corresponding search with session.createQuery("from B") works correctly too.

Description:
The hbm2java BasicRenderer generates an "is" getter method for fields of type java.lang.Boolean.  It should only do this for primitive fields of type boolean, and this breaks some other bean-based frameworks (such as the JSTL EL tags).

    Updated: Tue, 29 Jul 2003 12:03 PM

Description:
Add an 'isDirty(Object)' method to net.sf.hibernate.Session interface, and net.sf.hibernate.impl.SessionImpl.  This method would expose the logic on lines 2175-2200 of SessionImpl.java.  

This would allow applications to check or perform operations on dirty objects before flushing changes.  For example, this would allow an app to validate all dirty entities before flushing, and the validation method could invoke session methods or trigger lazy loads.  All of the validation errors could be collected for reporting to the user.  If there were validation errors, the app would not invoke flush.  This would allow the app to forward back to the input page and display the *current* state (without flushing, since there were errors) of the session / db to the user.  There could be other uses for an 'isDirty' method as well.

Thanks for your consideration.

     Status: Closed
   Priority: Major

    Project: Hibernate2
   Fix Fors:
             2.0.2
   Versions:
             2.0.1

   Assignee: Gavin King
   Reporter: Panagiotis Louridas

    Created: Tue, 22 Jul 2003 8:09 AM
    Updated: Sun, 27 Jul 2003 7:34 PM
Environment: RedHat Linux 9.0, JVM 1.4.2

Description:
Suppose we have a class hierarchy 
A <- B <- C.

In my case the class hierarchy is mapped as a joined-subclass hierarchy, but my observations may hold in general.

I use a Session with the default FlushMode setting (FlushMode.AUTO). I open the session, load an object of class B or C, perform some changes on it, do some queries and flush the session. When the session is flushed, only updates for the table pertaining to class A are issued by hibernate. 

If I manually flush just before the queries hibernate performs fine, issuing the proper updates for tables B and C. The same happens when I manually flush at the end of the transaction, after the queries, but having set the Session's flush mode to FlushMode.NEVER.

Description:
I want use multi-primary-key and foriegn-key as primary-key in my project. The insert and update operator can work correctly, but the load operator can not work correctly. After tracing the source code of hibernate, I think problem is the process of the <composition-id> with <key-many-to-one> element. 
I can not sure it is a bug or hibernate can not support my database schema. What can I do?

My Sample is:

---------------------------------------------------------------------
        Key: HB-214
    Summary: Deadlock in processing "composite-id -> key-many-to-one"
       Type: Bug

     Status: Unassigned
   Priority: Major

    Project: Hibernate2

   Assignee: 
   Reporter: Shining

    Created: Mon, 28 Jul 2003 5:28 AM
    Updated: Mon, 28 Jul 2003 5:28 AM
Environment: Windows2000 Professional with SP3, SQL Server 2000, Microsoft SQLServer 2000 JDBC Driver, SUN JDK 1.4.1_02, Elcipse 2.1 

Description:
I want use multi-primary-key and foriegn-key as primary-key in my project. The insert and update operator can work correctly, but the load operator can not work correctly. After tracing the source code of hibernate, I think problem is the process of the <composition-id> with <key-many-to-one> element. 
I can not sure it is a bug or hibernate can not support my database schema. What can I do?

My Sample is: 
-----------------------DataBase Schema---------------------------------

        Key: HB-215
    Summary: Resolving XML external entities from a XML file enclosed in a jar
       Type: Patch

     Status: Unassigned
   Priority: Minor

    Project: Hibernate2
 Components: 
             core
   Versions:
             2.0.1

   Assignee: 
   Reporter: Emmanuel Ligne

    Created: Mon, 28 Jul 2003 6:14 AM
    Updated: Mon, 28 Jul 2003 6:14 AM
Environment: Hibernate 2.0.1, windows 2000, jdk 1.4.1

Description:
When specifying something like <!ENTITY frame SYSTEM "/mypath/Frame.xml">, if both enclosing and enclosed XML files are in jar file, Frame.xml is not searched in the enclosing file jar
origin (as should be done regarding specif of relative URI search priority).

Updated net.sf.hibernate.util.DTDEntityResolver as well as its users
(ie XMLHelper and Configuration) so that optionnally a ClassLoader
can be passed. This classloader is tried to load resources as stream
given their systemId if the systemId is told to start with file:///
(ie relative uri).

code for DTDEntityResolver :

public class DTDEntityResolver implements EntityResolver {
	
	Log log = LogFactory.getLog(DTDEntityResolver.class);
	
	private final ClassLoader loader ;

	public DTDEntityResolver(ClassLoader loader) {
		super() ;
		this.loader = loader ;
	}

	private static final String URL = "http://hibernate.sourceforge.net/";
	private static final String FILE = "file:///" ;

	public InputSource resolveEntity (String publicId, String systemId) {
		if ( systemId!=null) {
			if (systemId.startsWith(URL) ) {
				log.debug("trying to locate " + systemId + " in classpath under net/sf/hibernate/");
				// Search for DTD
				ClassLoader classLoader = this.getClass().getClassLoader();
				InputStream dtdStream = classLoader.getResourceAsStream( "net/sf/hibernate/" + systemId.substring( URL.length() ) );
				if (dtdStream==null) {
					log.debug(systemId + "not found in classpath");
					return null;
				}
				else {
					log.debug("found " + systemId + " in classpath");
					InputSource source = new InputSource(dtdStream);
					source.setPublicId(publicId);
					source.setSystemId(systemId);
					return source;
				}
			}
			else if (systemId.startsWith(FILE))
			{
				InputStream childStream = loader.getResourceAsStream(systemId.substring(FILE.length())) ;
				if (childStream == null)
					return null ;
				else {
					log.debug("found " + systemId + " from classLoader");
					InputSource source = new InputSource(childStream);
					source.setPublicId(publicId);
					source.setSystemId(systemId);
					return source;
				}
			} else
				return null ;
		} else {
			// use the default behaviour
			return null;
		}
	}
	
}

Impacted code in XMLHelper :

Added constructor
	public static SAXReader createSAXReader(String file, ClassLoader cl) {
		SAXReader reader = new SAXReader();
		reader.setEntityResolver(new DTDEntityResolver(cl));
		reader.setErrorHandler( new ErrorLogger(file) );
		reader.setMergeAdjacentText(true);
		reader.setValidation(true);
		return reader;
	}
	
Modified DTD_RESOLVER instanciation :
	private static final EntityResolver DTD_RESOLVER = new DTDEntityResolver(XMLHelper.class.getClassLoader());


Configuration.java :

Modified some addXXX methods to use the new feature of XMLHelper :

	public Configuration addInputStream(InputStream xmlInputStream, ClassLoader src) throws MappingException {
		try {
			add( XMLHelper.createSAXReader("XML InputStream", src).read( new InputSource(xmlInputStream) ) );
			return this;
		}
		catch (MappingException me) {
			throw me;
		}
		catch (Exception e) {
			log.error("Could not configure datastore from input stream", e);
			throw new MappingException(e);
		}
	}
	
	/**
	 * Read mappings from an application resource
	 * @param path a resource
	 * @param classLoader a <tt>ClassLoader</tt> to use
	 */
	public Configuration addResource(String path, ClassLoader classLoader) throws MappingException {
		log.info("Mapping resource: " + path);
		InputStream rsrc = classLoader.getResourceAsStream(path);
		if (rsrc==null) throw new MappingException("Resource: " + path + " not found");
		return addInputStream(rsrc, classLoader);
	}
	
	/**
	 * Read a mapping from an application resource, using a convention.
	 * The class <tt>foo.bar.Foo</tt> is mapped by the file <tt>foo/bar/Foo.hbm.xml</tt>.
	 * @param persistentClass the mapped class
	 */
	public Configuration addClass(Class persistentClass) throws MappingException {
		String fileName = persistentClass.getName().replace(StringHelper.DOT,'/') + ".hbm.xml";
		log.info("Mapping resource: " + fileName);
		ClassLoader cl = persistentClass.getClassLoader() ;
		InputStream rsrc = cl.getResourceAsStream(fileName);
		if (rsrc==null) throw new MappingException("Resource: " + fileName + " not found");
		return addInputStream(rsrc, cl);
	}
	
	/**
	 * Read all mappings from a jar file
	 * @param resource an application resource (a jar file)
	 */
	public Configuration addJar(String resource) throws MappingException {
		
		log.info("Searching for mapping documents in jar: " + resource);
		
		final JarFile jarFile;
		final ClassLoader cl ;
		try {
			cl = Thread.currentThread().getContextClassLoader() ;
			jarFile = new JarFile(
				cl.getResource(resource).getFile()
			);
		}
		catch (IOException ioe) {
			log.error("Could not configure datastore from jar", ioe);
			throw new MappingException(ioe);
		}
		
		if (jarFile==null) throw new MappingException("Resource: " + resource + " not found");
		
		Enumeration enum = jarFile.entries();
		while( enum.hasMoreElements() ) {
			
			ZipEntry z = (ZipEntry) enum.nextElement();
			
			if( z.getName().endsWith(".hbm.xml") ) {
				log.info( "Found mapping documents in jar: " + z.getName() );
				try {
					addInputStream( jarFile.getInputStream(z), cl );
				}
				catch (MappingException me) {
					throw me;
				}
				catch (Exception e) {
					log.error("Could not configure datastore from jar", e);
					throw new MappingException(e);
				}
			}
		}
		
		return this;

Description:

Is it legal to map a many-to-one class to an interface. I have done this with
the father property (in the attached example), however, I am receiving errors when I try to load records where
the parent property is not null.

I have attached a set of files that demonstrate the error I am getting.  To use:
1. run the sql script to build files and populate data
   Note: I'm using MySQL so you might have to change for a different DB
2. Change eg.test configuration properites to reflect your DB setup
3. Run eg.test
   Everything should work fine and "Detail B1 - F3" should be printed
   to the output
4. Now in eg.test, change the configuration to use eg.IFather instead of eg.Father
5. In IDetail, change the m-1 father property from eg.Father to eg.IFather
6. Re-run and you will get this error.

    Created: Mon, 28 Jul 2003 11:19 AM
    Updated: Mon, 28 Jul 2003 11:21 AM

Description:
When searching in a subclass with a Criteria, *all* rows in the table are returned, not only those belonging to the subclass.

Example: Base class A, with subclasses B and C. Using session.createSearch(B.class).list() will incorrectly return all rows of both B and C, all of them instantiated as B's.

Searching for A works, both B's and C's get instantiated the right way. It is only when searching for a subclass it seems to ignore the discriminator field.

The corresponding search with session.createQuery("from B") works correctly too.

        Key: HBI-7
    Summary: Allow mapping class to more than one table/view
       Type: Improvement

     Status: Unassigned
   Priority: Major

    Project: Hibernate 1.2

   Assignee:

    Created: Mon, 28 Jul 2003 10:16 AM

Description:
I have multiple views that return different results, but all share a common structure 

I have a class defined to represent one row from the view 

I can map this class to the view and use a hibernate query to get a collection of objects 

Now I want to be able to define the second query that returns data from the second view. It seems like I would need to be able to map the same class to a different view but I don't think that will be allowed in Hibernate. 

For example: 

Here's the common class mapped to the first view: 

<class name="ResultSetRow" 
table="VW_REQUESTS_MANAGER" 
mutable="false"> 
<id name="reqId" column="req_id" type="long" unsaved-value="null"> 
<generator class="assigned"/> 
</id> 
<property name="name" column="name" type="string"/> 
<property name="date" column="date" type="timestamp"/> 
<property name="type" column="type" type="string"/> 
</class> 

and here's the Hibernate query that returns a collection of objects for each row returned by the view: 

<query name="PendingRequests.ForManager"> 
from ResultSetRow as list 
where list.managerId = :manager_id 
</query> 

The key issues are these: 
1) The structure of each result set will always 
be the same, only the contents will differ 
2) A set of different database views will be created that share the same structure but return different content according to their purpose 
3) I'd like to be able to share a common class instead of defining a different class for each different result set 
4) I'd like to be able to create a set of mappings for each database view that returns the common class that defines the structure of the result set 

Can I use a common class and map it to different table/views - or does the rule that one class maps to only one table prevent it ? 

Thanks!

    Summary: Resolving XML external entities from a XML file enclosed in a jar
       Type: Patch

     Status: Unassigned
   Priority: Minor

    Project: Hibernate2
 Components: 
             core
   Versions:
             2.0.1

   Assignee: 
   Reporter: Emmanuel Ligne

    Created: Mon, 28 Jul 2003 6:14 AM
    Updated: Mon, 28 Jul 2003 6:14 AM
Environment: Hibernate 2.0.1, windows 2000, jdk 1.4.1

Description:
When specifying something like <!ENTITY frame SYSTEM "/mypath/Frame.xml">, if both enclosing and enclosed XML files are in jar file, Frame.xml is not searched in the enclosing file jar
origin (as should be done regarding specif of relative URI search priority).

Updated net.sf.hibernate.util.DTDEntityResolver as well as its users
(ie XMLHelper and Configuration) so that optionnally a ClassLoader
can be passed. This classloader is tried to load resources as stream
given their systemId if the systemId is told to start with file:///
(ie relative uri).

code for DTDEntityResolver :

public class DTDEntityResolver implements EntityResolver {
	
	Log log = LogFactory.getLog(DTDEntityResolver.class);
	
	private final ClassLoader loader ;

	public DTDEntityResolver(ClassLoader loader) {
		super() ;
		this.loader = loader ;
	}

	private static final String URL = "http://hibernate.sourceforge.net/";
	private static final String FILE = "file:///" ;

	public InputSource resolveEntity (String publicId, String systemId) {
		if ( systemId!=null) {
			if (systemId.startsWith(URL) ) {
				log.debug("trying to locate " + systemId + " in classpath under net/sf/hibernate/");
				// Search for DTD
				ClassLoader classLoader = this.getClass().getClassLoader();
				InputStream dtdStream = classLoader.getResourceAsStream( "net/sf/hibernate/" + systemId.substring( URL.length() ) );
				if (dtdStream==null) {
					log.debug(systemId + "not found in classpath");
					return null;
				}
				else {
					log.debug("found " + systemId + " in classpath");
					InputSource source = new InputSource(dtdStream);
					source.setPublicId(publicId);
					source.setSystemId(systemId);
					return source;
				}
			}
			else if (systemId.startsWith(FILE))
			{
				InputStream childStream = loader.getResourceAsStream(systemId.substring(FILE.length())) ;
				if (childStream == null)
					return null ;
				else {
					log.debug("found " + systemId + " from classLoader");
					InputSource source = new InputSource(childStream);
					source.setPublicId(publicId);
					source.setSystemId(systemId);
					return source;
				}
			} else
				return null ;
		} else {
			// use the default behaviour
			return null;
		}
	}
	
}

Impacted code in XMLHelper :

Added constructor
	public static SAXReader createSAXReader(String file, ClassLoader cl) {
		SAXReader reader = new SAXReader();
		reader.setEntityResolver(new DTDEntityResolver(cl));
		reader.setErrorHandler( new ErrorLogger(file) );
		reader.setMergeAdjacentText(true);
		reader.setValidation(true);
		return reader;
	}
	
Modified DTD_RESOLVER instanciation :
	private static final EntityResolver DTD_RESOLVER = new DTDEntityResolver(XMLHelper.class.getClassLoader());


Configuration.java :

Modified some addXXX methods to use the new feature of XMLHelper :

	public Configuration addInputStream(InputStream xmlInputStream, ClassLoader src) throws MappingException {
		try {
			add( XMLHelper.createSAXReader("XML InputStream", src).read( new InputSource(xmlInputStream) ) );

	/**

Description:
I want use multi-primary-key and foriegn-key as primary-key in my project. The insert and update operator can work correctly, but the load operator can not work correctly. After tracing the source code of hibernate, I think problem is the process of the <composition-id> with <key-many-to-one> element. 
I can not sure it is a bug or hibernate can not support my database schema. What can I do?

Description:
Suppose we have a class hierarchy 
A <- B <- C.

In my case the class hierarchy is mapped as a joined-subclass hierarchy, but my observations may hold in general.

I use a Session with the default FlushMode setting (FlushMode.AUTO). I open the session, load an object of class B or C, perform some changes on it, do some queries and flush the session. When the session is flushed, only updates for the table pertaining to class A are issued by hibernate. 

If I manually flush just before the queries hibernate performs fine, issuing the proper updates for tables B and C. The same happens when I manually flush at the end of the transaction, after the queries, but having set the Session's flush mode to FlushMode.NEVER.

Okay, I understand now.

Hibernate does _not_ support "overriding" a property mapping on a <subclass> or <joined-subclass>.

It may well be possible to do what you are trying to do with a CompositeUserType.

What we want to do is map the name attribute on each concrete sybtype of Contact to a different implementation 
(an individual name has two components parts [first and last name] whereas an entity name has only one). 

My basic problem is, Hibernate seems to understand the model when inserting (the right things get into the DB), but when I load() it brings back null in the name attribute. 
The odd thing is, I've added a debug statement to the setName() method and hibernate first sets the name attribute to the right thing (an IndividualName object with the right values) then (inside that same call to the load() method) sets the attribute to null, *on the same instance of ContactIndividual*. 

This is the model for what I'm trying to do: 
public abstract class Contact{ 
public abstract Name getName(); 
public abstract void setName(Name name); 
} 
public class ContactIndividual extends Contact {...} 
public class ContectEntity extends Contact {...} 
public class Name { } 
public class IndividualName extends Name {...} 
public class EntityName extends Name {...}

[Hibernate-issues] [Hibernate-JIRA] Updated: (HB-213) Component attributes and class hierarchy polymorphism

[<leg...@at...>]

The following issue has been updated:

    Updater: Shorn Tolley (mailto:Sho...@nr...)
       Date: Sun, 27 Jul 2003 3:50 AM
    Comment:
This is a whole (Ant based) project that I use for testing these issues.  It is stripped down to the bone.  Remember that the model itself for this issue is not really very simple.
If you want to run the project, just unzip it, make a HibernateSimpleTest_lib directory and chuck your JDBC jars in there, then edit hibernate.properties and run the Ant "run" target.
    Changes:
             Attachment changed to HibernateSimpleTest.zip

[Hibernate-issues] [Hibernate-JIRA] Closed: (HB-138) Ant task for hbm2java

[<leg...@at...>]

Message:

   The following issue has been closed.

   Resolver: Max Rydahl Andersen
       Date: Sat, 26 Jul 2003 5:23 AM

Used the submitted task as inspiration - removed some assumptions in the task that tried to be intelligent on which files should be generated or not. This is not possible to do in the ant task without also implementing the logic already in hbm2java - thus I left it out from the task as we instead should extend hbm2java to handle it uniformly (if at all possible ;)
