Boa noite meus amigos,
Estou estudando flex e me deparei com um erro do qual não consigo me livrar.
Me é exibido a seguinte mensagem:
Ao meu ver está tudo correto
Vejam o código do ContatoDAO
public class ContatoDAO extends AbstractDAO<Contato> {
public ContatoDAO() {
super("Contato");
}
}[/code]
Agora do AbstractDAO
[code]package br.com.treinamento.modelo.dao;
import java.lang.reflect.Field;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

import br.com.treinamento.database.ConnectionFactory;
public abstract class AbstractDAO<T> {
private String tableName;
private Connection con;
private Class<T> clazz;
private Field[] fields;
@SuppressWarnings("unchecked")
public AbstractDAO(String tableName) {
this.tableName = tableName;
con = ConnectionFactory.getConnection();
try {
clazz = (Class<T>) Class.forName("br.com.treinamento.modelo.beans."
+ tableName);
fields = clazz.getDeclaredFields();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
@SuppressWarnings({ "finally" })
public ArrayList<T> getLista() {
ArrayList<T> lista = new ArrayList<T>();
String sql = String.format("SELECT * FROM %s ORDER BY id", tableName);
try {
PreparedStatement pstm = con.prepareStatement(sql);
ResultSet rs = pstm.executeQuery();
while (rs.next()) {
lista.add(montarObjeto(rs));
}
} catch (SQLException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
} finally {
return lista;
}
}
private T montarObjeto(ResultSet rs) throws IllegalAccessException,
SQLException, InstantiationException {
T objectDinamic = clazz.newInstance();
for (Field field : fields) {
field.setAccessible(true);
field.set(objectDinamic, rs.getObject(field.getName()));
}
return objectDinamic;
}
@SuppressWarnings("finally")
public T getById(Long id) {
String sql = String.format("SELECT * FROM %s WHERE id=%d", tableName,id);
PreparedStatement pstm;
ResultSet rs;
T objectDinamic = null;
try {
pstm = con.prepareStatement(sql);
rs = pstm.executeQuery();
rs.next();
objectDinamic = montarObjeto(rs);
} catch (SQLException e) {
e.printStackTrace();
throw new RuntimeException(e);
} finally {
return objectDinamic;
}
}

Estou usando o JBoss6 e o BlazeDS para comunicação entre as duas plataformas.
O driver do MySql está presente no server/default/lib do jboss
Serei grato mediante qualquer ajuda. 
Obrigado
