I am trying to capture JPA annotations in EMF editor (Soyatec) , generate
a code and then use Teneo to generate HBM file. It seems annotations are
not reflected in HBM file.

ecore annotation looks like :

<eClassifiers xsi:type="ecore:EClass" name="EQUser"
eSuperTypes="#//EQGlobalDomainObject">
<eAnnotations source="teneo.jpa">
<details key="appinfo" value="@Entity(name=t_eq_user)"/>
<details key="value" value="@Table(name=t_eq_user)"/>
</eAnnotations>

generated code has following comments :

@model annotation="teneo.jpa appinfo='@Entity(name=t_eq_user)'
value='@Table(name=t_eq_user)'"
@generated

But hibernate file doesnt have new table name :

<joined-subclass name="com.company.eqfc.model.orgdata.impl.EQUserImpl"
entity-name="EQUser" abstract="false" lazy="false"
extends="EQGlobalDomainObject" table="`equser`">

Can you pls help ?

Also how can we add multiple annotations through EMF editor ? it doesnt
allow multiple properties with 'appinfo' name ?

Can you check if the annotations are present in the generated EPackageImpl java class?
If they are then maybe it is best that I try your ecore. If not then the problem is in the java
packageimpl generation.

When I edit the ecore model in the emf ecore editor then the Property view shows a value field when
I click on the button on the right then a multi-line text editor opens in which I can enter multiple
lines with annotations.

I do see annotations in the Epackageimpl. Here is the method in the
package impl :

protected void createTeneoAnnotations() {
String source = "teneo.jpa";
addAnnotation
(jpaTableEClass,
source,
new String[] {
"appinfo", "@Entity(name=t_jpatable)"
});
}

Here is the Ecore file :

<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" name="jpatest"
nsURI="http://com.jpmorgan.jpatest" nsPrefix="com.jpmorgan.jpatest">
<eClassifiers xsi:type="ecore:EClass" name="JPATable">
<eAnnotations source="teneo.jpa">
<details key="appinfo" value="@Entity(name=t_jpatable)"/>
</eAnnotations>
<eStructuralFeatures xsi:type="ecore:EAttribute" name="name"
eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
</eClassifiers>
</ecore:EPackage>

Here is the HBM file generated from above ecore file :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD
3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">


<hibernate-mapping>
<class name="org.eclipse.emf.ecore.impl.DynamicEObjectImpl"
entity-name="JPATable" abstract="false" lazy="false" table="`jpatable`">

based on the annotation, table name in this case should be t_jpatable.

Appreciate your help.

Here is the ecore which creates a table with the name test_jpatable. The name of the entity is not
picked up, this is a bug. The table annotation works.

<?xml version="1.0" encoding="UTF-8"?>

Thx for quick response.

Unfortunately its still not working for me. Not sure if there is something
wrong with my setup. This is what I did during retest :

1:- Edited ecore file and made changes as suggested by you.

i.e. <details key="appinfo"
value=" @Entity(name="t_jpatable")
@Table( name="test_jpatable") "/>

2. Reloaded this ecore in genmodel and generated code. Above change is
reflected in JpatestPackageImpl

protected void createTeneoAnnotations() {
String source = "teneo.jpa";
addAnnotation
(jpaTableEClass,
source,
new String[] {
"appinfo",
"@Entity(name=\"t_jpatable\")\n@Table(name=\"test_jpatable\")"
});
}

3. Right clicked on jpatest.ecore file and then ran Teneo -> Generate EMF
- Hibernate O/R Mapping

4. Hibernate mapping file is generated which doesnt have above table name.

<class name="com.jpmorgan.jpatest.impl.JPATableImpl"
entity-name="JPATable" abstract="false" lazy="false" table="`jpatable`">

I am using Teneo 0.8.0.

Any clue ??

Okay, if you right click on the ecore file to create the hbm file then you don't need to re-generate
the java code, only if you use the hbdatastore without a hbm file then this is required.

Can you post the exact ecore you use or send me it by email?

This works for me but for testing I do not use the right click but use the HbDataStore (and then
call getMappingXML). Although the underlying code for the right-click menu option is the same as the
one used in the HbDataStore.

Can you try programmatically (initialize a hbdatastore)?

Here is the hbm I get:


<hibernate-mapping>
<class name="org.eclipse.emf.ecore.impl.DynamicEObjectImpl" entity-name="JPATable" abstract="false"
lazy="false" discriminator-value="t_jpatable" table="`test_jpatable`">
<meta attribute="eclassName">JPATable</meta>

access=" org.eclipse.emf.teneo.hibernate.mapping.identifier.Identifie rPropertyHandler ">
<meta attribute="syntheticId">true</meta>
<generator class="native"/>
</id>
<discriminator column="`dtype`" type="string"/>
<version name="e_version" column="e_version"

This works. That means there is some difference between the way hbm file
is generated from Epackage or Ecore. Epackage works as annotations are
added to Eclass. In case of Ecore I think it fails to interpret
eAnnotations from XML file.

One question. Can HbDataStore be initialized based on ecore ? If yes then
we can try to see if that works.

Many thanks for your quick help. Also let me know when next version of
Teneo will be available.

Can you check if the annotations are present in the generated EPackageImpl java class?
If they are then maybe it is best that I try your ecore. If not then the problem is in the java
packageimpl generation.

When I edit the ecore model in the emf ecore editor then the Property view shows a value field when
I click on the button on the right then a multi-line text editor opens in which I can enter multiple
lines with annotations.

I do see annotations in the Epackageimpl. Here is the method in the
package impl :

protected void createTeneoAnnotations() {
String source = "teneo.jpa";
addAnnotation
(jpaTableEClass,
source,
new String[] {

});
}

Here is the ecore which creates a table with the name test_jpatable. The name of the entity is not
picked up, this is a bug. The table annotation works.

Thx for quick response.

Unfortunately its still not working for me. Not sure if there is something
wrong with my setup. This is what I did during retest :

1:- Edited ecore file and made changes as suggested by you.

i.e. <details key="appinfo"
value=" @Entity(name="t_jpatable")
@Table( name="test_jpatable") "/>

2. Reloaded this ecore in genmodel and generated code. Above change is
reflected in JpatestPackageImpl

protected void createTeneoAnnotations() {
String source = "teneo.jpa";
addAnnotation
(jpaTableEClass,
source,
new String[] {
"appinfo",
"@Entity(name=\"t_jpatable\")\n@Table(name=\"test_jpatable\")"
});
}

3. Right clicked on jpatest.ecore file and then ran Teneo -> Generate EMF
- Hibernate O/R Mapping

4. Hibernate mapping file is generated which doesnt have above table name.

<class name="com.jpmorgan.jpatest.impl.JPATableImpl"
entity-name="JPATable" abstract="false" lazy="false" table="`jpatable`">

I am using Teneo 0.8.0.

Any clue ??

Okay, if you right click on the ecore file to create the hbm file then you don't need to re-generate
the java code, only if you use the hbdatastore without a hbm file then this is required.

Can you post the exact ecore you use or send me it by email?

Here is the complete ecore file :

<eClassifiers xsi:type="ecore:EClass" name="JPATable">

This works for me but for testing I do not use the right click but use the HbDataStore (and then
call getMappingXML). Although the underlying code for the right-click menu option is the same as the
one used in the HbDataStore.

Can you try programmatically (initialize a hbdatastore)?

Here is the hbm I get:


<hibernate-mapping>
<class name="org.eclipse.emf.ecore.impl.DynamicEObjectImpl" entity-name="JPATable" abstract="false"
lazy="false" discriminator-value="t_jpatable" table="`test_jpatable`">
<meta attribute="eclassName">JPATable</meta>
<meta attribute="epackage">http://com.jpmorgan.jpatest</meta>
<id type="long" name="e_id" column="e_id"
access=" org.eclipse.emf.teneo.hibernate.mapping.identifier.Identifie rPropertyHandler ">
<meta attribute="syntheticId">true</meta>
<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 ertyHandler ">
<meta attribute="syntheticVersion">true</meta>
</version>
<property name="name" lazy="false" insert="true" update="true" not-null="false" unique="false"
type="java.lang.String">
<column not-null="false" unique="false" name="`name`"/>
</property>
</class>
</hibernate-mapping>

This works. That means there is some difference between the way hbm file
is generated from Epackage or Ecore. Epackage works as annotations are
added to Eclass. In case of Ecore I think it fails to interpret
eAnnotations from XML file.

One question. Can HbDataStore be initialized based on ecore ? If yes then
we can try to see if that works.

Many thanks for your quick help. Also let me know when next version of
Teneo will be available.
