Corrupted files are downloaded

Question

Hi,
I have written a code to download .pdf docs contained in a zipped file. The code works fine mostly, but sometimes the zip file contains pdf of size 75KB only (although the size should be more than this).
Could anybody please suggest what can be the probably cause? Is it an error in pdf creation or zipping?
Thanks,
Amit

Amit,
I think the getPdf will get just the file name, I am not sure we have to define a static size byte array and write, See my below code to .zip the output log file,
Which is working fine,
String zipout = pageContext.getParameter("ZIPOUT");
if(zipout!=null && zipout.equals("Y"))
try
DataObject sessionDictionary = (DataObject) pageContext.getNamedDataObject("_SessionParameters");
HttpServletResponse response = (HttpServletResponse) sessionDictionary.selectValue(null, "HttpServletResponse");
HttpServletRequest request = (HttpServletRequest) sessionDictionary.selectValue(null, "HttpServletRequest");
String requestID = pageContext.getParameter("REQUESTID");
response.setHeader("Content-Disposition","p; filename=CatExtract"+requestID+".zip");
response.setContentType("application/x-zip-compressed");
ZipOutputStream zip = new ZipOutputStream(response.getOutputStream());
try
byte[] buffer = new byte[1024];
int bytesRead;
//to get the value of output directory
String logDir = pageContext.getProfile("XNC_DEBUG_LOG_DIRECTORY");
logDir = logDir.replaceFirst("log","out");
String fileName = logDir+"/o"+requestID+".out";
try
FileInputStream file = new FileInputStream(fileName);
try
ZipEntry entry = new ZipEntry(fileName);
zip.putNextEntry(entry);
while ((bytesRead = file.read(buffer)) != -1)
zip.write(buffer, 0, bytesRead);
zip.closeEntry();
pageContext.writeDiagnostics(entry.getName(), " added.",1);
catch (Exception ex)
pageContext.writeDiagnostics(this.getClass().getName(),"Exception "+ex,1);
finally {
file.close();
catch (IOException ex)
pageContext.writeDiagnostics(this.getClass().getName(),"Exception "+ex,1);
finally {
zip.close();
zip.flush();
}catch(Exception ex)
pageContext.writeDiagnostics(this.getClass().getName(),"Exception "+ex,1);
Thanks,
