Asked by: gudii9

Hi,

I am running follwoing java program to select, insert values into oracle 10g dfatabase table through RAD workspace.




import java.sql.*;



class dbtest {



 public static void main(String args[])   throws
ClassNotFoundException, SQLException {



   Class.forName("oracle.jdbc.driver.OracleDriver");

   // or you can use:

   // DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());



   Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl","deliverytest7","dbpasword");


   Statement stmt = conn.createStatement();

   ResultSet rset = stmt.executeQuery("select * from stud");

   while(rset.next())

    {

     System.out.println(rset.getInt(1));

     System.out.println(rset.getString(2));

     }

   rset.close();

   stmt.close();

   conn.close();

 }

}


It gives error message like invalid user name and password. I am able to connect to same schema through sql plus without any issues. Please advise. Any links, ideas, resources highly appreciated. Thanks in advance

Please show how you connect via sqlplus.

sqlplus deliverytest7/dbpasword

 

by: CEHJPosted on 2009-07-03 at 13:37:39ID: 24774302

>>I am able to connect to same schema through sql plus without any issues.

There's got to be something different. Are you sure it's not a different copy of the db?

 

by: mrjoltcolaPosted on 2009-07-03 at 13:39:34ID: 24774308

I agree with Charles. Invalid username/password error means you hit the instance.

That is why I want to see the explicit command used to connect via sqlplus.

Are there different dbs on the same box?

Also show:  lsnrctl services

 

by: gudii9Posted on 2009-07-03 at 13:39:55ID: 24774310

It is same copy of database schema i am hitting. I am able to connect using sqldeveloper also as in screenshot similar to sqlplus.

 

by: mrjoltcolaPosted on 2009-07-03 at 13:45:18ID: 24774324

That is fine, but please answer the specific questions above.

Oracle JDBC service name syntax requires a / in the JDBC URL nowadays. Your JDBC URL is using SID syntax (which is ok, but I am just pointing out the difference), yet your SQL Developer connection is using service syntax. Please try the SID option, or use sqlplus.

sqlplus user/pass@orcl

Again, how many databases are on your system?

 

by: basav_comPosted on 2009-07-03 at 13:52:35ID: 24774354

May be sillypoint.. but still wants to point out. Password is:
dbpasword     OR     dbpassword           (i.e. double ss).

Show the : sqlplus user/pass@orcl             result as pointed out by mrjoltcola.

 

by: gudii9Posted on 2009-07-03 at 13:55:55ID: 24774366

I only have one database running in my laptop with xp OS. Sqlplus i am not connecting through command prompt but from


start-->all programs--->oracle oracle 10g--->sqlplus etc as in screnshot.

How shall i change following statement to include service name instead of SID

Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl","deliverytest7","dbpasword");


Please advise

 

by: gudii9Posted on 2009-07-03 at 13:59:47ID: 24774381

through command prompt also i was able to connect as in screenshot

 

by: gudii9Posted on 2009-07-03 at 14:00:45ID: 24774392

screenshot is like this

 

by: mrjoltcolaPosted on 2009-07-03 at 14:08:06ID: 24774432

I don't understand why it is so difficult for you to follow my explicit directions above?

The reason I am asking you to connect with the _explicit_ syntax is to force the use of the TNS alias, if it exists. You've also not provided the output to the info asked for in:  http:#24774308

So, one last time, please try:

1) sqlplus deliverytest8/passwordxxx@orcl

2) Also show output of: lsnrctl services

 

by: basav_comPosted on 2009-07-03 at 14:08:07ID: 24774433

From the posted screenshot, from the password field I can see 10 masked stars. So, I guess the correct password is 'dbpassword'(10 digits) and not 'dbpasword' (9 digits).

Can you post the EXACT output of the following commands.

1. sqlplus deliverytest7/dbpasword

2. sqlplus deliverytest7/dbpassword
