I am trying to integrate emf,teneo and derby into one application.
However, a strange problem occured when i tried to configue the database
connection.Here is the code:
/////////////////////
Properties properties = new Properties();
properties.setProperty(PersistenceConfiguration.JDO_DATASTOR E_DRIVERNAME_PROPERTY,
"com.ibm.db2.jcc.DB2Driver");

properties.setProperty(PersistenceConfiguration.JDO_DATASTOR E_USERNAME_PROPERTY,
"sa");
properties.setProperty(PersistenceConfiguration.JDO_DATASTOR E_PASSWORD_PROPERTY,
"sa");
properties.setProperty(PersistenceConfiguration.AUTO_CREATE_ TABLES_PROPERTY, "true");
properties.setProperty(PersistenceConfiguration.CACHE_LEVEL_ 1_TYPE_PROPERTY,
"org.eclipse.emf.teneo.jpox.cache.EMFWeakRefCache");
// create/register the JpoxDataStore, set the db props and the epackages
to persist, initialize creates
// the database
String pmfName = "MyPMF"; // the name of the JpoxDataStore
JpoxDataStore jpoxDataStore =
JpoxHelper.INSTANCE.createRegisterDataStore(pmfName);
jpoxDataStore.setProperties(properties);
jpoxDataStore.setEPackages(new EPackage[] { CustomerPackage.eINSTANCE });
jpoxDataStore.initialize();
///////////////////////////////////
an exception was throwed when execute to "jpoxDataStore.initialize". and
here is the error information:
///////////////////////

where is the problem?
Hoping for response!
Thank you very much!

Hi Wangyan,
Are you maybe using jpox 1.2? Teneo is at jpox 1.1.8. For jpox 1.2 you need to add a plugin.xml
defining the teneo cache definitions. See here for the jpox documentation:
http://www.jpox.org/docs/1_2/extensions/level1_cache.html
Note that the Teneo cache is only required to ensure that eContainer pointers are correct, if you
are not interested in the correct value of the eContainer member then this cache is not required.
