Answer 1

This is occur due to wrong connectivity with database connection.
In your program you write 
Connection con = DriverManager.getConnection
                  ("jdbc:oracle:thin:@localhost:8080:orcl", "system","tiger");

Go to D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora

Here you find the file like this:

**abcd** =
     (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = **1521**))
           (CONNECT_DATA =
            (SERVER = DEDICATED)
            (SERVICE_NAME = abcd)
        )
     ) 

Now you write your connection as follow:

  ("jdbc:oracle:thin:@localhost:1521:abcd","your_db_name","your_password")  

After this you don't get the exception.
