Uploaded files are incomplete

[Lance Hill]

I am trying to upload a pdf to the server's file system. I seem to be able to upload the file, but it is incomplete.

Once it is on the server, I would like to use an action to find the pdf and display it to the browser. This also seems to break the file. If I put a good pdf in place on the server, when I stream it to the browser, I get an error that the file is damaged.

When I look at the file after it is uploaded, I can see that it is not the complete file, so I suspect something is going wrong when I am reading the file in.

Any advice on how to ensure I get the entire (and unbroken) file would be appreciated. Any examples of better or easier ways to do this would be even more appreciated.

Code follows.

File Upload Action:

<snip>
InputStream stream = file.getInputStream();
OutputStream bos = new FileOutputStream(fileLoc + fileName);
int bytesRead = 0;
byte[] buffer = new byte[8192];
while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) 
{
bos.write(buffer);
}
bos.close();
stream.close();  
</snip>

View File Action

File file = new File(filePath);
FileInputStream stream = new FileInputStream(file);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ServletOutputStream sos = response.getOutputStream();
int bytesRead = 0;
byte[] buffer = new byte[8192];

response.setContentType("application/pdf");
response.setHeader("Pragma", "No-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 1);

while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) 
{
baos.write(buffer);
}
stream.close();
sos.flush();
baos.writeTo(sos);
sos.close();
