I solved my problem not using derby :(
Appear the list is more interested in voting logos, than solving
critical bugs.

the error message is:
select count(*) from TB_BIBLIO_AUTORIZACAO: Exception
"java.lang.ClassCastException:
org.apache.derby.impl.sql.execute.CountAggregator' was emited
evaluating expression.
The table TB_BIBLIO_AUTORIZACAO has 8 records, with 3 columns (one
integer, 2 varchar). There are no null values on contents.
I recently upgraded derby to 10.1.2.1 (from 10.1.1). I tried to
"downgrade" to 10.1.1, but gives same error. The app is being
developed under Apache Tomcat 5.5.9, and derby libraries are under
$JAKARTA/commons/lib. Other queries (for authentication, as example)
are working fine.
I'll appreciate any help.
