 Post subject: NullPointerException in AbstractQueryImpl Verify parameters

I have upgraded my application to Hibernate 3.0.2, mainly to use the getCurrentSession feature. This appears to have had the desired effect: I am albe to insert data in a CMP transaction in WebSphere 5,1 (which this is running in). I have removed all transaction and sesssion management code from my application, and only use the getCurrentSession() method. However within certain transactions there is a need to read data via the QueryImpl class before doing the insert / update, and I am getting a NullPointerException when I invoke

q.list()

in the following line from AbstractQueryImpl

positionalValueSpan += ( (Type) object ).getColumnSpan( session.getFactory() );

I can't see how session would be null, since getCurrentSession() should create one if one does not exist. Any help is appreciated.

Thanks,

Jeff



Hibernate version: 3.0.2

Mapping documents:

Code between sessionFactory.openSession() and session.close():


session = getSessionFactory().getCurrentSession();

Query q = session.createQuery(getQueryString());

bindParameterValues(q, 0);

List l = q.list();


....



protected int bindParameterValues(Query query, int start) throws HibernateException {

if (mCriteria != null && mCriteria.size() > 0) {
// assumes that types are all of span 1
Iterator iter = iterateExpressionEntries();
int result = 0;
while (iter.hasNext()) {
SQLQueryImpl.CriterionEntry ee = (SQLQueryImpl.CriterionEntry)iter.next();
Object[] values = ee.getCriterion().getValues();
Type[] types = ee.getCriterion().getTypes();
for (int i = 0; i < values.length; i++) {
Type type = (i >= types.length) ? types[0] : types[i];
query.setParameter(result + i, values[i], type);
}
result += values.length;
}
return result;
}
else {
return 0;
}
}

Surely more likely that Type is null....

You're right. In HIbernate2, column had a getType / setType methods, which no longer exist in Hibernate 3. WHne I upgraded my code, I did not handle this change appropriately.
