In first testing the 1.0.5 RC, I get the error below. This worked as is in
1.0.4. Something different with the count use in the RC?
Caused by: java.lang.ClassCastException: java.lang.String cannot be cast to
java.lang.Long which comes from this line as shown in more detail below:
count = new Integer(((Long)obj[2]).intValue());
This came out of getting a count out of a ReportByCriteria result set.
Where the columns look like:
private static final String[] crColumns = new String[]{"countryId",
"regionId", "count(countryId)","count(regionId)"};
ReportQueryByCriteria query = new
ReportQueryByCriteria(specificActiveServiceLocationQueryVO,
crColumns, crit, true);
.....
.....
obj = (Object[]) resultsIt.next();
count = new Integer(((Long)obj[2]).intValue());
This could be jdbc-driver issue. If OJB doesn't know the field (detect a
not mapped field), in your case the count(...) field, the jdbc-type is
resolved by using the ResultSet metadata (rsMetaData.getColumnType(...))
of the jdbc-driver.
You can try to use the query.setJdbcTypes method to specify the
sql-types, then OJB resolves the proper java-jdbc-types
http://db.apache.org/ojb/docu/guides/jdbc-types.html
int types[] = new int[]{Types.DECIMAL, Types.VARCHAR, Types.BIGINT};
ReportQueryByCriteria q = QueryFactory.newReportQuery(Person.class, crit);
q.setAttributes(new String[]{"id", "firstname", "count(*)"});
q.setJdbcTypes(types);
This should work for all none mapped query fields. If the field is
mapped the type setting will be ignored - this is a bug and will be
fixed in 1.0.5rc2.
