Hi all,
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_URL_PROPERTY,
"jdbc:derby:net://localhost:1527/MyDbTest");
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:
///////////////////////

(org.eclipse.emf.teneo.jpox.JpoxHelper).

////////////////////////
I have added the "org.eclipse.emf.teneo.jpox.jar" into plugins as while as
java build path of this project, why such exception has been reported? The
help document in the eclipse.org also shows that its crucial to set this
cache property and it should be added in this manner.
where is the problem?
Hoping for response!
Thank you very much!
