from which line ?

[chintan shah]

when you get the result data into your ResultSet, the cursor is placed before the first row...hence you need to use the next method on the resultset object to place the cursor on the correct position and then try extracting data from it
cheers!!

Use this

    
ResultSet rs=stmt.executeQuery("select username from table1 where act=1");
if(rs.next())
{
 out.println(rs.getString("username"));
}

Hi Balaji kkk welcome to Javaranch ,

Firstly it looks like your display name does not follow the Javaranch naming policy . Please change it using the My Profile link above.
Then add code tags to your code. Unformatted code is hard to read and will bring down the number of responses you get.
