SQLJ Error

Question

I am trying to write the following prog to display the detail of
the table
prod (pname varchar2(20), price number(10)),using Positional
Iterator. but
couldnt write a simple program . here is the code, as I compile
the code it
says
testpos.sqslj:45.2-45.44: Error: Invalid cursor type un FETCH
statement:MyIter.
I am new to JAVA, I am not able to fix the error. Please help me
out.
import java.sql.*;
import oracle.sqlj.runtime.*;
// iterator for the select
#sql iterator MyIter (String pname, int price);
class testpos
//Main method
public static void main (String args[])
try {
// set the default connection to the URL, user, and password
// specified in your connect.properties file
Oracle.connect(testpos.class, "connect.properties");
testpos ti = new testpos();
ti.runExample();
//end of try
catch (SQLException e)
System.err.println("Error running the example: " + e);
} //End of method main
//Method that runs the example
void runExample() throws SQLException
String prodname= null;
int pprice=0;
MyIter prods;
#sql prods = {SELECT pname, price FROM prod};
while (true)
#sql {FETCH :prods INTO :prodname, :pprice};
if (prods.endFetch()) break;
System.out.println("Name: " +prodname);
System.out.println("Price: " +pprice);
prods.close();

When declaring a positional iterator, only the datatype of each
column should be declared; the column names are not defined.
Change it to the following:
#sql iterator MyIter (String, int);
And it should work. I tested it.
