Hi,
I am working on an application using Teneo (v 0.8.0), hibernate and EMF.
The application model is generated from XML schema, and the hibernate
mapping file is generated by using teneo plugin in eclipse.
I am trying to use the Named queries in the application but I am getting
following exception:
org.hibernate.MappingException: Named query not known:
getCustomerEventsQuery
at
org.hibernate.impl.AbstractSessionImpl.getNamedQuery(Abstrac tSessionImpl.java:70)
at org.hibernate.impl.SessionImpl.getNamedQuery(SessionImpl.jav a:1260)
at
com.giki.server.service.impl.CalendarServiceImpl.getNamedEve ntQuery(CalendarServiceImpl.java:153)
at
com.giki.server.service.impl.CalendarServiceImpl.getCustomer Events(CalendarServiceImpl.java:74)
.... 24 more
I have defined the named query as follows in hibernate.hbm.xml file:
</hibernate-mapping>
......
......
<query name="getCustomerEventsQuery">
<![CDATA[
from EventType event where event.timeReceived >=:fromDate and
event.timeReceived <= :toDate and event.customer.userToken = :userToken
order by event.timeReceived
]]>
</query>
</hibernate-mapping>
The query is correct and work properly when I used it to create
hibernate query object. I also tried to use the named queries in other
application using just hibernate (without teneo) it worked fine with
above steps.
Please help.
Regards,
Prashant

Hi Martin,
Thanks for your reply.
I am not generating the mapping file at runtime. I generate the mapping
file using the eclipse Teneo plugin using the ecore file.
How to direct teneo to use the mapping file? I just put the mapping file
in the application classpath (in the source directory).
Also can you tell me what option need to set in Teneo and how to set
them? And how can I debug the datastore to find out the problem.
I am using hibernate.properties file and its contents are as follows (it
also present in the application source directory):
hibernate.connection.driver_class=com.mysql.jdbc.Driver
hibernate.connection.url=jdbc:mysql://127.0.0.1:3306/myapp
hibernate.connection.username=<username>
hibernate.connection.password=<password>
hibernate.dialect=org.hibernate.dialect.MySQLDialect
Following is the code used to create the hibernate session factory:
final String dataStoreName = "dataStoreName";
final HbDataStore dataStore =
HbHelper.INSTANCE.createRegisterDataStore(dataStoreName);
// Configure the EPackages used by this DataStore.
dataStore.setEPackages(new EPackage[] {
GikidocPackage.eINSTANCE });
// Initialize the DataStore. This sets up the Hibernate
mapping and
// creates the corresponding tables in the database.
dataStore.initialize();
sessionFactory = dataStore.getSessionFactory();
Please help me to resolve the issue.
Thanks & Regards,
Prashant

Hi Prashant,
There should be a class PersistenceOptions which should have an option like USE_MAPPING_FILE, you
have to set this option to "true" and pass it on to the datastore (setPersistenceProperties method).
The datastore is not a very big class, there is a piece of code which uses the above option and
calls another method to retrieve the hbm file and pass it on to the configuration object. There is a
utility method which is called whcih walks through the classpath of the model classes, so if your
generated model package is in org.my.model.package.impl then teneo will search here:
org.my.model.package.impl
org.my.model.package
org.my.model
org.my
org
So your hibernate.hbm.xml should be in the above path somewhere.
Be sure to have the hibernate.hbm.xml checked in the build.properties so that it is copied to the
build path.
Btw, the exact naming of the methods I refer to maybe slightly different as I don't have the 0.8.0
source code directly available where I am now.

Hi Martin,
It worked. I made the required changes in the code to initialize the
datastore and the application can now read the hibernate.hbm.xml file.
Thanks for your help.
Thanks & Regards,
