i am using Hibernate to get Column names of the table.I Created one Method and I am passing my Table Name to that Method While executing I am Getting This Exception : No Dialect mapping for JDBC type: -1 Could any one Help me out.Thanks

Below Mycode:

Dao class:

public class Dao {
        public static void main(String[] args) {
            Dao o=new Dao();
             ArrayList list=o.getTableDesc("examtype");
        System.out.println ("listlistlist"+list);
        }
    public  ArrayList<String>  getTableDesc(String tableName) {
            System.out.println("getFieldNames:start" + tableName);
            Object[] a;
            List<Object[]> fieldNames = new ArrayList<Object[]>();
            ArrayList<String> tabFieldNames = new ArrayList<String>();
            Session ses = HibernateUtil.getSessionFactory().openSession();
            try {
                String queryStr = "DESCRIBE "  + tableName;                 
                fieldNames = (List<Object[]>) ses.createSQLQuery(queryStr).list();
                System.out.println("fieldNamesfieldNames"+fieldNames);
                for (int i = 0; i < fieldNames.size(); i++) {
                    a = fieldNames.get(i);
                    tabFieldNames.add(a[0].toString());
                }
            } catch (Exception e) {
                e.printStackTrace();
                System.out.println("exception " + e);
            } finally {
                ses.close();
            }
            System.out.println("getFieldNames:end" + tabFieldNames.toString());
            return tabFieldNames;
        }  
    }

Hibernate.cfg.xml:

    <hibernate-configuration>
        <session-factory>

Change the property name of dialect as follows:

name="dialect" change it to name="hibernate.dialect"

and should also add the mapping resource="path where the respective(entity class related as if Person entity-->Person.hbm.xml) hbm.xml file presents"

and run it.
