[Zhong Li <we...@gmail.com>]

here is the method webelite.jsf.ojb.Core.getDataObject(Class c, Object key)

public static Object getDataObject(Class c, Object key ){
Object dataObject=null;
try
{
IdentityFactory idf = broker.serviceIdentity();
String[] pNames = {"id"};
Object[] pValues = {key};
Identity id = idf.buildIdentity(c, pNames , pValues);

Query query = new QueryByIdentity(id);
dataObject = broker.getObjectByQuery
(query);//broker.getObjectByIdentity(id);
}
catch (PersistenceBrokerException ex)
{
if (broker != null)
{
broker.abortTransaction();
}
ex.printStackTrace();
}
return dataObject;
}


How could the exception happened? Is it bug or wrong of usage?

Thanks.
