[Teneo] Possible to Override Generation of hibernate.hbm.xml? [message #72941] Tue, 27 February 2007 16:15 Go to next message

Hi,

I have some problems getting in control of the id and version columns in my
project. I need to have those attributes both in the ecore and in my model
interface (non synthetic), in the EMF-Editor, however, they are not visible.

I tried to set persistency annotations in the model interfaces with little
success:

FOR THE ID COLUMN:
/**
* @model id="true" required="true"
* @generated
*/
@Id @GeneratedValue(strategy=GenerationType.AUTO)
int getId();

/**
* @generated
*/
void setId(int value);

RESULT: org.hibernate.id.IdentifierGenerationException: ids for this class
must be manually assigned before calling save()
(I notice that the generated PK `id` is auto_increment in
MySql)

FOR THE VERSION COLUMN:
/**
* @model required="true"
* @generated
*/
@Version
int getVersion();

/**
* @generated
*/
void setVersion(int value);

RESULT: org.hibernate.MappingException: Duplicate property mapping of
version found

As I will have quite some tables in my model I'm not so keen in modifying
all generated model interfaces in order to add any annotations. What I
rather would like is to utilize the Teneo utility and so generate EMF -
Hibernate OR mapping direct from the ecore file. In order to do that I have
added persistenceProperties.setProperty(PersistenceOptions.USE_MAP PING_FILE,
"true"); to the persistency property in the EditorPlugin. The generated
hibernate.hbm.xml has anyway to be modified in the following way:

GENERATED:
<id name="id" type="int">
<column not-null="true" unique="false" name="`id`"/>
</id>

MODIFIED:
<id name="id" type="int" column="id" unsaved-value="0">
<generator class="identity"/>
</id>

GENERATED:
<version name="version" column="version"
access=" org.eclipse.emf.teneo.hibernate.mapping.property.VersionProp ertyHand
ler">
<meta attribute="syntheticVersion">true</meta>
</version>

MODIFIED:
<version name="version" column="version"
access=" org.eclipse.emf.teneo.hibernate.mapping.property.VersionProp ertyHand
ler"/>

With the above modifications my EMF-Editor is working and I have no problems
persisting the model objects to the database. Ids are generated and version
is incremented.

My question is if one somehow can override the mappings being generated in
order to achieve above modified id- and version-elements?

Thanks,
Bj

Hi Björn,
In Teneo annotations are not specified in the java code but in the model (ecore or xsd) or in a
separate xml.
So the @Id and @GeneratedValue(strategy=GenerationType.AUTO) annotations should be specified there.
If your id attributes all use an EDataType defined by yourselve then you can add the annotations to
the EDataType (so one place instead of at each attribute).

Hi Martin,

Thanks for your reply. It definitely brought me on the right path and so I
decided to define my own id and version datatypes in ecore:

<eClassifiers xsi:type="ecore:EDataType" name="AmsetId"
instanceClassName="int">
<eAnnotations source="teneo.jpa/Id">
<details key="appinfo"
value="@GeneratedValue(strategy=&quot;AUTO&quot;)"/ >
</eAnnotations>
</eClassifiers>
<eClassifiers xsi:type="ecore:EDataType" name="AmsetVersion"
instanceClassName="int">
<eAnnotations source="teneo.jpa/Version">
<!-- <details key="appinfo" value="@Version"/> -->
</eAnnotations>
</eClassifiers>

Those two datatypes are referenced in i.e StatusType:

<eClassifiers xsi:type="ecore:EClass" name="StatusType">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="name"
lowerBound="1"
eType="ecore:EDataType
http://www.eclipse.org/emf/2002/Ecore#//EString"/>
<eStructuralFeatures xsi:type="ecore:EAttribute" name="id"
lowerBound="1"
eType="#//bergauer/rcp/amset/model/datatypes/AmsetId"
iD="true"/>
<eStructuralFeatures xsi:type="ecore:EAttribute" name="version"
lowerBound="1"
eType="#//bergauer/rcp/amset/model/datatypes/AmsetVersion"/ >
</eClassifiers>


I now have the following results:

PersistenceOptions.USE_MAPPING_FILE set true:
- The hibernate.hbm.xml I now have the id-element with generator,
non-synthetic. Id is generated as expected
- The version attribute that I define in ecore isn't recognized with
annotation yet. In the hibernate.hbm.xml I have one version-element (with
synthetic set true) and in the database I get two fields e_version and
version. The PersistenceOptions.ALWAYS_VERSION is set false in the
EditorPlugin.

<class entity-name="StatusType" abstract="false" lazy="false"
discriminator-value="StatusType" table="`statustype`">
<meta attribute="eclassName">StatusType</meta>
<meta
attribute="epackage">ch.bergauer.rcp.amset.model.systemattributes.amset.xmi <
/meta>
<id name="id" type="int">
<column not-null="true" unique="false" name="`id`"/>
<generator class="native"/>
</id>
<discriminator column="`dtype`" type="string"/>
<version name="e_version" column="e_version"
access=" org.eclipse.emf.teneo.hibernate.mapping.property.VersionProp ertyHand
ler">
<meta attribute="syntheticVersion">true</meta>
</version>
<property name="name" lazy="false" insert="true" update="true"
not-null="true" unique="false" type="java.lang.String">
<column not-null="true" unique="false" name="`name`"/>
</property>
</class>

PersistenceOptions.USE_MAPPING_FILE set false:
Neither id nor version work is reqognized. In the in-menory mapping I
have no generator element for the id-element:

<class entity-name="StatusType" abstract="false" lazy="false"
discriminator-value="StatusType" table="`statustype`">
<meta attribute="eclassName">StatusType</meta>
<meta
attribute="epackage">ch.bergauer.rcp.amset.model.systemattributes.amset.xmi <
/meta>
<id name="id" type="int">
<column not-null="true" unique="false" name="`id`"/>
</id>
<discriminator column="`dtype`" type="string"/>
<property name="name" lazy="false" insert="true" update="true"
not-null="true" unique="false" type="java.lang.String">
<column not-null="true" unique="false" name="`name`"/>
</property>
<property name="version" lazy="false" insert="true" update="true"
not-null="true" unique="false" type="int">
<column not-null="true" unique="false" name="`version`"/>
</property>
</class>

The solution using the hibernate.hbm.xml seems to be the better way, so I
think I will go on using PersistenceOptions.USE_MAPPING_FILE=true.
Apperently I'm doing something wrong with the version though. Am I
overlooking something obvious?

cheers,
Bj

Hi Björn,
Afaics the <details...> tag in the eAnnotations of the AmsetVersion EDataType is commented out using
xml comment characters (<!-- and -->). Could that be a reason?

Also the id annotation does not seem to be completely correct. The source should teneo.jpa and then
the value should also contain the @Id annotation.

There should be no difference in generating the mapping file manually and then use that or the
automatic mapping in-memory (it also generates an in-memory mapping). I would suggest to use the
automatic in-memory mapping until you want to do extensive manual changes (for example to map to a
current db schema).

Hi Martin,

Well the out-commented element is an artifact from my first try. Oddly
enough I think it was about how you meant it should look like :

<eClassifiers xsi:type="ecore:EDataType" name="AmsetId"
instanceClassName="int">
<eAnnotations source="teneo.jpa">
<details key="appinfo" value="@Id
@GeneratedValue(strategy=&quot;AUTO&quot;)"/>
</eAnnotations>
</eClassifiers>
<eClassifiers xsi:type="ecore:EDataType" name="AmsetVersion"
instanceClassName="int">
<eAnnotations source="teneo.jpa">
<details key="appinfo" value="@Version"/>
</eAnnotations>
</eClassifiers>

It didn't work with the automatic mapping (and I think I missed out testing
it with the hibernate.hbm.xml) so I abandoned it and found other suggestions
in the newsgroup extending teneo.jpa to teneo.jpa/Id... :o/

After having reimplemented the eDataTypes, as above, both Id and Version
works well using the hibernate.hbm.xml! :) The automatic mapping, though,
still doesn't recognize the annotations:

hibernate.hbm.xml:

<class entity-name="StatusType" abstract="false" lazy="false"
discriminator-value="StatusType" table="`statustype`">
<meta attribute="eclassName">StatusType</meta>
<meta
attribute="epackage">ch.bergauer.rcp.amset.model.systemattributes.amset.xmi <
/meta>
<id name="id" type="int">
<column not-null="true" unique="false" name="`id`"/>
<generator class="native"/>
</id>
<discriminator column="`dtype`" type="string"/>
<version name="version" type="int">
<column not-null="true" unique="false" name="`version`"/>
</version>
<property name="name" lazy="false" insert="true" update="true"
not-null="true" unique="false" type="java.lang.String">
<column not-null="true" unique="false" name="`name`"/>
</property>
</class>

automatic mapping:

<class entity-name="StatusType" abstract="false" lazy="false"
discriminator-value="StatusType" table="`statustype`">
<meta attribute="eclassName">StatusType</meta>
<meta
attribute="epackage">ch.bergauer.rcp.amset.model.systemattributes.amset.xmi <
/meta>
<id name="id" type="int">
<column not-null="true" unique="false" name="`id`"/>
</id>
<discriminator column="`dtype`" type="string"/>
<property name="name" lazy="false" insert="true" update="true"
not-null="true" unique="false" type="java.lang.String">
<column not-null="true" unique="false" name="`name`"/>
</property>
<property name="version" lazy="false" insert="true" update="true"
not-null="true" unique="false" type="int">
<column not-null="true" unique="false" name="`version`"/>
</property>
</class>

Could it have to do with the version of Teneo that I use? I'm currently
using Teneo 0.7.5 Maintenance Build. I did download version 0.8.0 but had to
deactivate it as I'm using Eclipse 3.2.1.

Greetings,
Bj

Hi Björn,
What could explain the difference is that after a change in the ecore (like adding an annotation)
you have to regenerate the java model code to get the change in ecore to the runtime layer.
For the automatic mapping the ecore model is not read from the ecore file but from the in-memory
ecore representation. This in-memory representation is created by the generated PackageImpl and can
be out of sync with the ecore file.
So can you try again (if you like) after regenerating the java model code?

Hi Martin,

I use to regenerate all code (model, edit, editor) every time I make a
change to the ecore model. Now I even deleted the model code and generated
it from scratch. I'm sorry to say that it still is a problem with the
autogenerated mapping. It's exactly the same as in my prevoious post.
Could it be a problem that the eDataTypes are in another package than the
model code?

Greetings,
Bj

No problem. Actually, I am not sure why you would need to move the edatatype to the same package.
When you said regenerate, did you regenerate the model code of both epackages?

Hi Björn,
In Teneo annotations are not specified in the java code but in the model (ecore or xsd) or in a
separate xml.
So the @Id and @GeneratedValue(strategy=GenerationType.AUTO) annotations should be specified there.
If your id attributes all use an EDataType defined by yourselve then you can add the annotations to
the EDataType (so one place instead of at each attribute).

Hi Martin,

Thanks for your reply. It definitely brought me on the right path and so I
decided to define my own id and version datatypes in ecore:

<eClassifiers xsi:type="ecore:EDataType" name="AmsetId"
instanceClassName="int">
<eAnnotations source="teneo.jpa/Id">
<details key="appinfo"
value="@GeneratedValue(strategy=&quot;AUTO&quot;)"/ >
</eAnnotations>
</eClassifiers>
<eClassifiers xsi:type="ecore:EDataType" name="AmsetVersion"
instanceClassName="int">
<eAnnotations source="teneo.jpa/Version">
<!-- <details key="appinfo" value="@Version"/> -->
</eAnnotations>
</eClassifiers>

Those two datatypes are referenced in i.e StatusType:

<eClassifiers xsi:type="ecore:EClass" name="StatusType">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="name"
lowerBound="1"
eType="ecore:EDataType
http://www.eclipse.org/emf/2002/Ecore#//EString"/>
<eStructuralFeatures xsi:type="ecore:EAttribute" name="id"
lowerBound="1"
eType="#//bergauer/rcp/amset/model/datatypes/AmsetId"
iD="true"/>
<eStructuralFeatures xsi:type="ecore:EAttribute" name="version"
lowerBound="1"
eType="#//bergauer/rcp/amset/model/datatypes/AmsetVersion"/ >
</eClassifiers>


I now have the following results:

PersistenceOptions.USE_MAPPING_FILE set true:
- The hibernate.hbm.xml I now have the id-element with generator,
non-synthetic. Id is generated as expected
- The version attribute that I define in ecore isn't recognized with
annotation yet. In the hibernate.hbm.xml I have one version-element (with
synthetic set true) and in the database I get two fields e_version and
version. The PersistenceOptions.ALWAYS_VERSION is set false in the
EditorPlugin.

<class entity-name="StatusType" abstract="false" lazy="false"
discriminator-value="StatusType" table="`statustype`">
<meta attribute="eclassName">StatusType</meta>
<meta
attribute="epackage">ch.bergauer.rcp.amset.model.systemattributes.amset.xmi <
/meta>
<id name="id" type="int">
<column not-null="true" unique="false" name="`id`"/>
<generator class="native"/>
</id>
<discriminator column="`dtype`" type="string"/>
<version name="e_version" column="e_version"
access=" org.eclipse.emf.teneo.hibernate.mapping.property.VersionProp ertyHand
ler">
<meta attribute="syntheticVersion">true</meta>
</version>
<property name="name" lazy="false" insert="true" update="true"
not-null="true" unique="false" type="java.lang.String">
<column not-null="true" unique="false" name="`name`"/>
</property>
</class>

PersistenceOptions.USE_MAPPING_FILE set false:
Neither id nor version work is reqognized. In the in-menory mapping I
have no generator element for the id-element:

<class entity-name="StatusType" abstract="false" lazy="false"
discriminator-value="StatusType" table="`statustype`">
<meta attribute="eclassName">StatusType</meta>
<meta
attribute="epackage">ch.bergauer.rcp.amset.model.systemattributes.amset.xmi <
/meta>
<id name="id" type="int">
<column not-null="true" unique="false" name="`id`"/>
</id>
<discriminator column="`dtype`" type="string"/>
<property name="name" lazy="false" insert="true" update="true"
not-null="true" unique="false" type="java.lang.String">
<column not-null="true" unique="false" name="`name`"/>
</property>
<property name="version" lazy="false" insert="true" update="true"
not-null="true" unique="false" type="int">
<column not-null="true" unique="false" name="`version`"/>
</property>
</class>

The solution using the hibernate.hbm.xml seems to be the better way, so I
think I will go on using PersistenceOptions.USE_MAPPING_FILE=true.
Apperently I'm doing something wrong with the version though. Am I
overlooking something obvious?

cheers,
Bj

Hi Björn,
Afaics the <details...> tag in the eAnnotations of the AmsetVersion EDataType is commented out using
xml comment characters (<!-- and -->). Could that be a reason?

Also the id annotation does not seem to be completely correct. The source should teneo.jpa and then
the value should also contain the @Id annotation.

There should be no difference in generating the mapping file manually and then use that or the
automatic mapping in-memory (it also generates an in-memory mapping). I would suggest to use the
automatic in-memory mapping until you want to do extensive manual changes (for example to map to a
current db schema).

Hi Martin,

Well the out-commented element is an artifact from my first try. Oddly
enough I think it was about how you meant it should look like :

<eClassifiers xsi:type="ecore:EDataType" name="AmsetId"
instanceClassName="int">
<eAnnotations source="teneo.jpa">
<details key="appinfo" value="@Id
@GeneratedValue(strategy=&quot;AUTO&quot;)"/>
</eAnnotations>
</eClassifiers>
<eClassifiers xsi:type="ecore:EDataType" name="AmsetVersion"
instanceClassName="int">
<eAnnotations source="teneo.jpa">
<details key="appinfo" value="@Version"/>
</eAnnotations>
</eClassifiers>

It didn't work with the automatic mapping (and I think I missed out testing
it with the hibernate.hbm.xml) so I abandoned it and found other suggestions
in the newsgroup extending teneo.jpa to teneo.jpa/Id... :o/

After having reimplemented the eDataTypes, as above, both Id and Version
works well using the hibernate.hbm.xml! :) The automatic mapping, though,
still doesn't recognize the annotations:

hibernate.hbm.xml:

<class entity-name="StatusType" abstract="false" lazy="false"
discriminator-value="StatusType" table="`statustype`">
<meta attribute="eclassName">StatusType</meta>
<meta
attribute="epackage">ch.bergauer.rcp.amset.model.systemattributes.amset.xmi <
/meta>
<id name="id" type="int">
<column not-null="true" unique="false" name="`id`"/>
<generator class="native"/>
</id>
<discriminator column="`dtype`" type="string"/>
<version name="version" type="int">
<column not-null="true" unique="false" name="`version`"/>
</version>
<property name="name" lazy="false" insert="true" update="true"
not-null="true" unique="false" type="java.lang.String">
<column not-null="true" unique="false" name="`name`"/>
</property>
</class>

automatic mapping:

<class entity-name="StatusType" abstract="false" lazy="false"
discriminator-value="StatusType" table="`statustype`">
<meta attribute="eclassName">StatusType</meta>
<meta
attribute="epackage">ch.bergauer.rcp.amset.model.systemattributes.amset.xmi <
/meta>
<id name="id" type="int">
<column not-null="true" unique="false" name="`id`"/>
</id>
<discriminator column="`dtype`" type="string"/>
<property name="name" lazy="false" insert="true" update="true"
not-null="true" unique="false" type="java.lang.String">
<column not-null="true" unique="false" name="`name`"/>
</property>
<property name="version" lazy="false" insert="true" update="true"
not-null="true" unique="false" type="int">
<column not-null="true" unique="false" name="`version`"/>
</property>
</class>

Could it have to do with the version of Teneo that I use? I'm currently
using Teneo 0.7.5 Maintenance Build. I did download version 0.8.0 but had to
deactivate it as I'm using Eclipse 3.2.1.

Greetings,

Hi Björn,
What could explain the difference is that after a change in the ecore (like adding an annotation)
you have to regenerate the java model code to get the change in ecore to the runtime layer.
For the automatic mapping the ecore model is not read from the ecore file but from the in-memory
ecore representation. This in-memory representation is created by the generated PackageImpl and can
be out of sync with the ecore file.
So can you try again (if you like) after regenerating the java model code?

Hi Martin,

I use to regenerate all code (model, edit, editor) every time I make a
change to the ecore model. Now I even deleted the model code and generated
it from scratch. I'm sorry to say that it still is a problem with the
autogenerated mapping. It's exactly the same as in my prevoious post.
Could it be a problem that the eDataTypes are in another package than the
model code?

Greetings,
Bj

No problem. Actually, I am not sure why you would need to move the edatatype to the same package.
When you said regenerate, did you regenerate the model code of both epackages?
