Hi,
Im writin the followin code to connect with oracle database.im also using toad .I keep geetin errors even if i declare private String AQC1_UID = ""; and so on..

import java.sql.*;

 public class Login {
public static void main(String[] args)
{
    String AQC1_UID = "";
    String AQC1_USER_PWD = "";

   public Login(String AQC1_UID,String AQC1_USER_PWD)
{   this.AQC1_UID=AQC1_UID;
    this.AQC1_USER_PWD=AQC1_USER_PWD;

  }


 /* public void setUsername(String AQC1_UID) {
     this.AQC1_UID=AQC1_UID;
  }

  public void setPassword(String AQC1_USER_PWD) {
     this.AQC1_USER_PWD=AQC1_USER_PWD;
   }
*/

  public boolean  validate(String user,String password) {
  String query="select * from AIP_QM_CONTROL1";
  System.out.println("---------------------"+query);
   String DbUserName="";
   String DbPassword="";
   String finalUser="";
  try {


Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");


Connection con=DriverManager.getConnection

("jdbc:oracle:thin@10.192.22.17:1521:AIPUAT1");


Statement stat=con.createStatement();


ResultSet rst=stat.executeQuery(query);

while(rst.next())

  {
   DbUserName=rst.getString("AQC1_UID");

   DbPassword=rst.getString("AQC1_USER_PWD");

   if (AQC1_UID.equals(DbUserName) && AQC1_USER_PWD.equals(DbPassword)) {

   break;
     }


   }
 return true;
 }
 catch(Exception e){

 e.printStackTrace();
 return false;
 }
};
}

}

code showin error while executing in cmd prompt...

illegal start of expression ---public Login(String AQC1_UID,String AQC1_USER_PWD)
                                         ^

can you please tell me whats wrong with the code..

Edited 3 Years Ago by mike_2000_17: Fixed formatting

public static void main(String[] args)
{
    String AQC1_UID = "";
    String AQC1_USER_PWD = "";

    public Login(String AQC1_UID,String AQC1_USER_PWD)
    { 
        this.AQC1_UID=AQC1_UID;
        this.AQC1_USER_PWD=AQC1_USER_PWD;
    }
.....

When indented properly, the error becomes obvious. Do you see it?

I believe you meant to close of main as an empty method, but didn't.

thx so much!!!..it wrked..but isnt displayin the query result..perhaps somethin wrong wit connection..

Well, what doers the stack trace show?

One thing though,

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

Connection con=DriverManager.getConnection("jdbc:oracle:thin@10.192.22.17:1521:AIPUAT1");

Why are you loading the driver for the JDBC-ODBC Bridge, then using a url for the Oracle JDBC Thin Driver?

String jdbcDriver=System.getProperty("jdbc.driver.class");
Class.forName(jdbcDriver);

Connection con=DriverManager.getConnection("jdbc:oracle:thin@10.192.22.17:1521:AIPUAT1","trn1","trn1");

is this not correct?..hw do we do it then?..

Your loading the wrong Driver though. Also, look in the logfiles for the web container and get the "real" stacktrace, not the InternalServerError one.

Hi,
the problem was not with the code..there was error in ip address of db server..it does not reside on my m/c so..had to use another ip address..
