Runtime r = Runtime.getRuntime();
Process p = r.exec("C:\\Condor\\test\\QueStatus.bat");
PrintWriter out;
String title = "Que Status";
response.setContentType("text/html");
out = response.getWriter();
FileReader fr = new FileReader ("C:\\Condor\\test\\output.txt");
for (int chr = fr.read(); chr != -1; chr = fr.read()){
     out.print(chr);
}

Couple of things. First you should search the forums for how to properly exec a dos batch file. There are some problems you may run into especially with io. I suspect you may not actually be running that batch file at all.
I would test outputing a text file separately from execing the batch file.
Here is some code so you don't have to output 1 char at a time. Setting the content length and closing the output stream might help.
File downloadFile = new File("c:\\blah\\blah\\blah");
response.setContentLength((int)downloadFile.length());
response.setContentType("text/html");
ServletOutputStream out = response.getOutputStream();
FileInputStream fis = new FileInputStream(downloadFile);
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = fis.read(buffer)) != -1) {
out.write(buffer, 0, bytesRead);
fis.close();
out.close();
