FileInputStream fin = new FileInputStream("FileName");
DataInputStream din = new DataInputStream(fin);

System.out.println("IN getFileName()():3333333333");

DefaultStyledDocument styledDoc = new DefaultStyledDocument();

System.out.println("IN getFileName()():4444444444444");

//Creating a RTF Editor kit
RTFEditorKit rtfKit = new RTFEditorKit();

//Populating the contents in the blank styled document
rtfKit.read(din,styledDoc,0);
Document doc = null;

doc = styledDoc.getDefaultRootElement().getDocument();

String str= doc.getText(0,doc.getLength());
