Issue with RandomaccessFile ReadLine method.

Hi,
I implemented the following while loop  after doing a write to a file :
raf_name=new RandomAccessFile("c:\\movie_name29.txt","rw");
raf_name.writeBytes(ss_name + "\r\n");
 while((text1 = raf_name.readLine()) != null)
                        {
                                if (text1.equalsIgnoreCase(searchString_name))
                             {
                                 count_names=count_names+1;
                                 if (count_names >5)
                                    {
                                       
                                       break;
                                       
                                    }
                                 }
                             }


However the code doesn't seems to be getting into the While loop at all. Any reasons why It might be doing so.
Regards

It is because you are at the end of the file after the call to writeBytes().

add the following between writeBytes() and the while loop and you will return to the beginning of your file:

raf_name.seek(0);
