why text file store in unix operating system can't be read

I have promblem .Currently i using both jsp and io class in to store value in a text file and mysql database .The promblem is that I can view in window platform the content of the text file ,but not in UNIX platform . Below are the syntax
<%
//String save2 = request.getParameter("flag");
String fileName = request.getParameter("fileName"); //get file name from download_process.jsp
String usr = request.getParameter("usr");
String passwd = request.getParameter("passwd");
System.out.println("f " +fileName);

String s[] = fileName.split(":");
String file1 = s[0];
String file2 = s[1];
System.out.println("fiel " +file2);
response.setContentType("text");
response.setHeader("Content-Disposition","attachment;filename=" + file2);

int Read1;
FileInputStream stream1 = null;
try {
File f = new File("c:/mysql/data/mrs/download/" +file2);
System.out.println("ff " +f);
stream1 = new FileInputStream(f);

System.out.println("stea " +stream1);
while ((Read1 = stream1.read()) != -1){
out.write(Read1);
}//end while
out.flush();
}//end try
finally {
if (stream1 == null){
stream1.close();
}//end if
}//end finally
