Example: JDBC Callable Produre for Stored SQL in MS Access

Question

I searched the net to find how this works. Firing a select and getting a resultset. I found certain pointers but couldn't find a complete solution. Although this would seem as not necessary but could be needed by a student or someone working with Access for the portability of it.
It was accomplished using JDBC-ODBC.
This is the stored query in the mdb : "getPassword"
{color:#0000ff}
SELECT password FROM Admin WHERE name=@username;
{color}
This is the DBMS using class: "XYZDatabase.java"
{color:#ff0000}
import java.sql.*; public class XYZDatabase { Connection con; CallableStatement cstmnt; Statement stmnt; ResultSet results; public XYZDatabase() { try { Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); con = DriverManager.getConnection("jdbc:odbc:XYZBuses"); stmnt = con.createStatement(); } catch(ClassNotFoundException e) { System.out.println("err in class 1:" e); } catch(SQLException e) { System.out.println("err in sql 1:" e); } } public void finalize() { try { stmnt.close(); con.close(); } catch(SQLException e) { System.out.println("err in sql 2:" e); } } public boolean checkPassword (String username, String password) { String pass = null; try { cstmnt = con.prepareCall("{exec getPassword ?}"); cstmnt.setString(1,username); cstmnt.execute(); results = cstmnt.getResultSet(); while(results.next()) pass = results.getString(1); cstmnt.close(); } catch(SQLException e) { System.out.println("err in sql 3:" e ); e.printStackTrace(); } System.out.println(pass); if (pass==null) return false; else if (password.equals(pass)) return true; return false; } }
{color}{color:#000000}This one is invocation : "Tester.java"
{color}{color:#008000}
public class Tester { public static void main (String args[]) { XYZDatabase db = new XYZDatabase(); System.out.println(db.checkPassword("imran","imran")); } }
{color}{color:#000000}Hope someone would find it handy someday :)
