- The infinite file error can be solved when the data will be read continuously from the file. 

- The error can be solved by using the keys that provide only the resources that are required. 

- The following program is as follows:

osw.write ("HTTP/1.0 200 OK\n\n"); 

while (c != -1) { 

sb.append((char)c); 

c = fr.read(); 

} 

osw.write (sb.toString()); 

- This converts the requested file in such a way that if the file exists it shows the messages as ok otherwise it shows an error.

- Limited file access is to be given to the file to remove the error from the infinite file type.
