I'm having trouble figuring out what the following stacktrace means.
(i.e., how to fix it)
It seems like I've got all files where they need to be, and I'm able
to successfully run the verify mapping test. (I'm using MySql)
Here's my setUp from DatabaseTest.java:
public void setUp()
{
try
{
service = new FamNetServiceImpl();
}
catch (DatastoreException e)
{
e.printStackTrace();
}
}
and the offending code from FamNetServiceImpl.init()
(as called from the constructor):
private void init() throws DatastoreException
{
odmg = OJB.getInstance();
db = odmg.newDatabase();
try
{
db.open("repository.xml", Database.OPEN_READ_WRITE);
}
catch (Exception e)
{
throw DatastoreException.datastoreError(e);
}
}
