java - JdbcOdbc Error. i cant connect to the ODBC driver -


i'm studying program , i've tried solve myself, seems can't understand went wrong.

how can connect database? :)

here code below:

package payroll.system; import java.io.ioexception; import java.io.datainputstream; import java.io.fileinputstream; import java.sql.connection; import java.sql.drivermanager; import java.sql.sqlexception; import javax.swing.jdialog; import java.io.*; import java.util.*; import java.net.*;   public class clsconnection {         string url = "";         string username = "";         string password = "";       public connection setconnection(connection conn, string username, string password )      {         try     {          properties props = new properties();         string filename = "makedb.ini";        fileinputstream in = new fileinputstream(filename);         props.load(in);         string drivers = props.getproperty("jdbc.drivers");         if(drivers != null)         system.setproperty("jdbc.drivers", drivers);          url = props.getproperty("jdbc.url");          username = props.getproperty("jdbc.username");          password = props.getproperty("jdbc.password");           conn = drivermanager.getconnection(url,username,password);      }catch(sqlexception e)         {             system.err.println("sql exception");             e.printstacktrace();          }             catch(ioexception e)            {                system.out.println("\nio exception");            }             catch (exception e)             {                 system.out.println("\nanother error");             }             return conn;      }     }

this error after compile program:

sql exception java.sql.sqlexception: [microsoft][odbc driver manager] data source name not found , no default driver specified @ sun.jdbc.odbc.jdbcodbc.createsqlexception(jdbcodbc.java:6964) @ sun.jdbc.odbc.jdbcodbc.standarderror(jdbcodbc.java:7121) @ sun.jdbc.odbc.jdbcodbc.sqldriverconnect(jdbcodbc.java:3080) @ sun.jdbc.odbc.jdbcodbcconnection.initialize(jdbcodbcconnection.java:323) @ sun.jdbc.odbc.jdbcodbcdriver.connect(jdbcodbcdriver.java:174)

this due fact have not set odbc driver. set odbc driver need go administrative tools under control panel , chose appropriate driver setup odbc. can visit msdn more details. hope helps.
