Teneo: More than one class with same name [message #69358]

Tue, 30 January 2007 06:19

Eclipse User

Hi,

As I am having more than one ecore models, it is possible that classes
in different models can have the same name though in different packages.

By default, hibernate file generated by Teneo does not qualify entity
name with package, so that result in duplicate mapping error.

I tried to qualify entities with full package name then hibernate
complains that duplicate import and suggests:

try using auto-import="false"

So just wondering, where & how to specify this?
Though during initialization I specify some hibernate properties using

hbds.setHibernateProperties

and I don’t see this property in Environment class of hibernate.

Another issue is, if in case I don’t want to persist one of the entity
i.e. more than one class with same name in different packages), then I
comment out mapping for that class in hibernate file, but class still
exist in package and Teneo complains that more then one EClass with same
name:

java.lang.IllegalArgumentException: There is more than one EClass with
the same name (. . . . . A different EClassResolver should be used.

Any idea how to solve it?

Hi,
How did you qualify the entity name (using the QUALIFY_ENTITY_NAME persistenceoption?)? Can you post
the last part of the stacktrace (incl. the exception message)?

With the other issue, are you sure that the mapping xml file is used? You need to tell Teneo
explicitly that a mapping file should be used and where it is used (using the persistenceoption:
PersistenceOptions.USE_MAPPING_FILE).

Can you also post the ecore if the above does not help?

auto-import is set on the hibernate-mapping tag in the mapping xml:
<hibernate-mapping
schema="schemaName" (1)
default-cascade="none|save-update" (2)
auto-import="true|false" (3)
package="package.name" (4)
/>
but I would not try that just now, it should work without setting auto-import explicitly.

Hi Martin,

I am using the option PersistenceOptions.USE_MAPPING_FILE with value "true"
but not the QUALIFY_ENTITY_NAME, I am not sure what should be its value.

In hibernate file, I have added full package name i.e.

<joined-subclass entity-name="com.pilz.pas.network.model.Network" ...
<joined-subclass entity-name="com.pilz.pas.platform.model.Network" ...

Now, I tried changing line to

<hibernate-mapping>
to
<hibernate-mapping auto-import="false">

and I get error::

!MESSAGE There is more than one EClass with the same name (Network in
EPackage model and model. A different EClassResolver should be used.
!STACK 0
java.lang.IllegalArgumentException: There is more than one EClass with
the same name (Network in EPackage model and model. A different

Hi Parvez,
It is described here:
http://www.elver.org/hibernate/options.html

see QUALIFY_ENTITY_NAME. If you use that then the naming issue should be solved and you don't need
to edit the xml file.
Btw, the entityname should not be set to the java classname but to the (qualified) eclass name.

Thanks Martin.

I will try using:

props.setProperty(PersistenceOptions.QUALIFY_ENTITY_NAME,Per sistenceOptions.QUALIFY_ENTITY_NAME_NSPREFIX);

And I guess, if one hibernate file contains 2 or more classes with same
name then Teneo will use

<meta attribute="epackage">...</meta>

to find package name, is it?

Hi Parvez,
The entity-name in the xml will be qualified. You can set the option and see how the mapping file
looks. Note you need to use the setpersistenceproperties on the hbdatastore for these options (and
setHibernateProperties for the hibernateproperties).

Sorry Martin, I "think" may be I got confused now about how
QUALIFY_ENTITY_NAME is going to work.

It looks to me that this option may not work for me, because I generate
hibernate file before running the application i.e. by right clicking on
ecore file and I use PersistenceOptions.USE_MAPPING_FILE, "true".
So I guess that won’t change hibernate file, but may be it can update
the loaded xml data. I will try it and will update accordingly.

Updating the loaded xml will not work I think (afaik).

You can also write a small java app (with just a static main method) which calls
HbHelper.INSTANCE.generateMapping to generate a mapping file. This method allows you to pass the
persistenceproperties.
