The reason is because the JSF file may have fail to parse it. But it does not appear after defining it. So, this article’s purpose is to define a header correctly for the JSF file. It occurs after successfully defining a ‘ui:composition’ tag to use a certain template. The problem in this article is the JSF file cannot parse a certain part of HTML element. That previous article exist in this link with the title of ‘How to Solve Error Message XML Parsing Error: prefix not bound to a namespace when running Java Web Application using Primefaces Framework’. While ((byteRead = inputStream.read()) != -1) Try to run this program and compare the time with the ones using legacy File I/O (on big files) you will see NIO performs much faster.This article is actually part or the continuation of the previous article. OutputStream outputStream = new FileOutputStream(outputFile) InputStream inputStream = new FileInputStream(inputFile) ("Please provide input and output files") * Copy one file to another using low level byte streams, one byte at a time. The source file and destination file are provided from command line’s arguments: import java.io.* Reading and Writing Binary Files Using FileInputStream and FileOutputStreamThe following examples use the FileInputStream and FileOutputStream classes to perform low level binary I/O.This program copies one file to another, one byte at a time. Whereas the BufferedInputStream and BufferedOutputStream are more efficient by buffering the input stream and output stream to reduce the number of calls to the native API.Now, let’s see some code examples. Moving down, the implementation classes FileInputStream and FileOutputStream are for reading and writing streams of raw bytes, one or multiple bytes at a time. write(byte): writes the specified array of bytes to the output stream.write(int): writes the specified byte to the output stream.Similarly, the abstract class OutputStream defines two primary methods for writing bytes to an output stream: This method returns -1 if there’s no more data or the end of the file is reached.
