title: How to read a big clob data from a file?
body: <p>I need to read a file line by line.<br>
  The data in the file can be anything, a small string or a huge Clob/Blob/XML.<br>
  But I am facing a problem, I am using <code>String row = dataInputStream.readLine()</code> to get the data, line by line. But if it is a big Clob/Blob/XML data, this method is throwing error, because it is not able to fit the huge data into the String. What should I do?</p>
