problems reading database settings from repository.xml

[Lukas Severin <lu...@mindcast.se>]

I get the following error when running a simple sample using OJB :

My client is doing a simple persistance of an account object : 

PersistenceManagerFactory factory = new OjbStorePMF();
PersistenceManager pm = factory.getPersistenceManager();
Transaction tx = pm.currentTransaction();
Account account = new Account(...)

try {
    tx.begin();
    pm.makePersistent(account);
    tx.commit();
} catch (Exception e) {
    e.printStackTrace();
} finally {
    if (tx.isActive()) tx.rollback();
    pm.close();
}

My repository.xml looks like this :

...
<jdbc-connection-descriptor
platform="MySQL"
jdbc-level="2.0"
driver="com.mysql.jdbc.Driver"
protocol="jdbc"
subprotocol="mysql"
dbalias="//localhost:3306/myDB"
username="admin"
password="adminpass"/>

Since I dont run inside a container I dont have any xml setting up jndi's and datasources.


Any help would be greatly appreciated !
