Hi,
I'm a total newbie to Teneo and not much better (but a little) with
Hibernate, and I'm trying to use Hibernate's ability to bind sessions to
the current thread.
If I try to use hibernate.properties or hibernate.cfg.xml with the
current_session_context_class=thread property, Teneo/Hibernate are
cheerfully ignoring me.
What's more, every time I try to use anything except directly setting
properties via dataStore.setHibernateProperties() I get this error:
Hibernate Dialect must be explicitly set
So, two questions:
1. Why am I seeing this? It looks like nothing is picking up my
properties, though if I bypass Teneo totally, Hibernate works just fine;
sessionFactory = new Configuration().configure().buildSessionFactory()
works correctly, so Hibernate CAN locate the resource.
2. Is this (attempting to use thread-bound sessions) actually possible
with Teneo?
Regards,
Neil Brennan

Hi,
I use the method of specifying the properties in a hibernate.properties
file in /src directory, as shown here
http://www.elver.org/hibernate/tutorialone/tutorial1_2.html
Which is copied across by Eclipse automatically to the bin directory
which is on the classpath. And I get exactly the same error as Neil
despite having specified the dialect in the hibernate.properties file.
If I set it programatically then all is well apart form the next problem.
The other problem is that despite having these in my eclipse.ini
-vmargs
-server
-Dcom.sun.management.jmxremote
-Xms80m
-Xmx768m
-XX:MaxPermSize=128m
-XX:+UseParallelGC
-XX:+UseParallelOldGC
I still get Out of Memory heap space errors when I attempt to generate?
I watch the memory and the Java process is crashing out after 100MB,
despite having 768m at its disposal and -Xmx512m in the Java runtime
arguments in the Run dialog set.
Ideas?
Thx.

Hi Neil,
Hmm, I checked and this is a bug (within the datastore.initialize I do configuration.setProperties
which replaces the properties created from the environment). Can you enter a bugzilla for this? This
will be solved in the next build.
As a workaround you can set the properties directly on the datastore: datastore.setProperties().
Thread-bound sessions should work fine with Teneo.

Hi David,
Yes indeed a bug, see my reply to Neil.
Regarding your out-of-memory issue. Do you run generate mapping from the eclipse menu or
programmatically?
The only thing I can think of is that the run uses a different launch configuration which does not
have the -Xmx512m, just guessing here.

Hi,
If you mean the hibernate mapping I use initialize() method as below.
This class is the same as it was the last time you saw it months ago.
// the name of the datastore
String hbName = "MyGenSec";
// the name of the database, this database should exist but does
not need to contain tables
String dbName = "GCSM";
// Set the database information, Environment is
org.hibernate.cfg.Environment
final Properties props = new Properties();
props.setProperty(Environment.DRIVER, "com.mysql.jdbc.Driver");
props.setProperty(Environment.USER, "tLoader");
props.setProperty(Environment.PASS, "UUUUUUU");
props.setProperty(Environment.URL, "jdbc:mysql://localhost:3306/" +
dbName);
props.setProperty(Environment.DIALECT,
org.hibernate.dialect.MySQL5InnoDBDialect.class.getName());
props.setProperty(PersistenceOptions.MAXIMUM_SQL_NAME_LENGTH ,
"30");
props.setProperty(PersistenceOptions.ID_FEATURE_AS_PRIMARY_K EY,
"true");
props.setProperty(PersistenceOptions.DEFAULT_ID_FEATURE_NAME ,
"id");
props.setProperty(PersistenceOptions.JOIN_COLUMN_NAMING_STRA TEGY, "simple");
props.setProperty(PersistenceOptions.ALSO_MAP_AS_CLASS, "false");
props.setProperty(PersistenceOptions.DEFAULT_TEMPORAL_VALUE,
"DATE");
props.setProperty(PersistenceOptions.DISABLE_ECONTAINER_MAPP ING, "true");
props.setProperty(PersistenceOptions.ALWAYS_VERSION, "false");
props.setProperty(PersistenceOptions.ALWAYS_MAP_LIST_AS_BAG,
"true");
props.setProperty(PersistenceOptions.INHERITANCE_MAPPING,
"JOINED");
// create the HbDataStore
HbDataStore hbds = HbHelper.INSTANCE.createRegisterDataStore(hbName);
// set the relational database to use and other properties
// to set Teneo specific options call
hbds.setPersistenceProperties(props);
hbds.setHibernateProperties(props);
// sets its epackages stored in this datastore
hbds.setEPackages(new EPackage[]{GensecPackage.eINSTANCE});
// initialize, also creates the database tables
hbds.initialize();
When you check in the fix for the properties file pickup, will it have a
dependency on 3.5M1 like the last maintenance build? I am using 3.4.

David

Hi,
Looks like this was a one off, rebooted and the thing generates just fine.
