No Dialect mapping for JDBC type: -1

hi guys

I am doing a hibernate excercise. I am not sure what i am doing wrong. This is what i have in my DAO

++++++++++++++++++++++++
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
Transaction trans = session.beginTransaction();
try {
SQLQuery sqlQuery = session.createSQLQuery("SELECT * from dbad.rst_item;");
List getSize = sqlQuery.list();
System.out.println("Size "+getSize);
trans.commit();

System.out.println("----------- Close the session------------- ");

session.close();
}
catch (Exception exp)
{

System.out.println("Rollback the session");
exp.printStackTrace();
// trans.rollback();
}

++++++++++++++++

This is my hibernate.cgf.xml

<session-factory>


<property name="connection.datasource">jdbc/dwpastoreds</property>
<property name="show_sql">true</property>
<property name="dialect">org.hibernate.dialect.DB2390Dialect</property>
<property name="current_session_context_class">thread</property>

<mapping resource="spResourceMapping/TestVO.hbm.xml"/>

</session-factory>

+++++++++++++++++++++++++++++++++++++++++++

and this is my TestVO.hbm.xml

<hibernate-mapping>

<class name="com.aoc.judiciary.framework.ValueObjects.TestVO" table="RST_ITEM">

<id name="userId" column="1">
<generator class="native"/>
</id>
<property name="name" column="2"/>
<property name="city" column="3"/>

<property name="ssn" column="4"/>
<property name="dob" column="5"/>

<property name="extradbmappingfield1" column="6"/>
<property name="extradbmappingfield2" column="8"/>
<property name="extradbmappingfield3" column="9"/>
<property name="extradbmappingfield4" column="10"/>
<property name="extradbmappingfield5" column="13"/>
<property name="extradbmappingfield6" column="14"/>
<property name="extradbmappingfield7" column="15"/>
<property name="extradbmappingfield8" column="16"/>

</class>

</hibernate-mapping>

and i get this exception

"SELECT * from dbad.rst_item;"

This doesn't look like a valid SQL query. Have you tried copying and pasting it in your db SQL tool to see if it actually runs?

Mark

yeah, it works, its a simple select statement
select * from table;

is there any problem with the statement? i am using db2

thanks

Which version of DB2 are you using? Anything to do with the dialect that you are using?

Depending on the version of DB2 that you are using, you might want to try out one of thes DB2 dialects mentioned here

thanks guys . its working now

SQLQuery sqlQuery = session.createSQLQuery("SELECT * from dbad.rst_item;");
List getSize = sqlQuery.list();
System.out.println("Size "+getSize);

tha above statements print "Size 40" in console. however

when i say something like

for (int i = 1; i < getSize .size(); i++) {
TestVO resultSet = (TestVO) getSize .get(i);
System.out.println("userID:" + resultSet.getUserId());

}

its not working, thats weird. the length is perfectly fine , but when i try to print the values , the code breaks, it says

>>>Could not invoke the service() method on servlet HibernateTestServlet. Exception thrown : java.lang.ClassCastException: java.lang.Object

any ideas?
