How to convert a text file content to String in JSP?

Question

Hi,
I need to read the content of a text file and convert it into String and display it on to a JSP file.
But the codings below don't work. Please advise me on how can i display the text file content.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
File adCheck = new File("list.txt");
fis = new FileInputStream(adCheck);
int Length = adCheck.length();
byte arr[] = new byte[Length];
int dataRead = 0;
int totalData = 0;
while(totalData <Length)
     dataRead = fis.read(arr,totalData,Length);
     totalData += dataRead;
String Content = new String(arr);//byte array converted to String
arr = null;

     InputStreamReader in=new InputStreamReader(fis);
      StringWriter out=new StringWriter();
      char[] buffer=new char[8192];
      int sizeRead;
      while ( ( sizeRead=in.read(buffer, 0, 8192) ) != -1 )
        out.write(buffer, 0, sizeRead);
     String content=out.toString();
