Hi
I have an struts application which does the
authorisation in filters. Authorisation is done using
the request.getParameter("menu").
This filter works very fine But fails when the the
request is of enctype="multipart/form-data". i.e when
i am using the file upload in the page.
To solve this i used the commons-fileupload to get the
Parameter. Now again the parameter is available at
filter, but the request fails at Action of Struts.
Now how do i convert the request back to the original
form. If you could get me the code, it would be highly
appreciated.
My parsing code:
int contentLength = request.getContentLength();
// Copy the request's input stream.
final ServletInputStream bis =
request.getInputStream();
final BufferedOutputStream bos;
final Object bodyData;
if (contentLength > 50000)
{
// Use a disk file for storing the body data.
bodyDataFile = File.createTempFile("body-",
".data");
bodyDataFile.deleteOnExit();
final FileOutputStream fos = new
FileOutputStream(bodyDataFile);
bos = new BufferedOutputStream(fos);
bodyData = bodyDataFile;
}
else
{
// Use a byte array for storing the body data.
final ByteArrayOutputStream baos = new
ByteArrayOutputStream();
bos = new BufferedOutputStream(baos);
bodyData = baos;
}
final int BUFFER_SIZE = 10240;
byte[] buffer = new byte[BUFFER_SIZE];
int toBeCopied = contentLength;
while (toBeCopied > 0)
{
int read = bis.read(buffer, 0,
Math.min(BUFFER_SIZE, toBeCopied));
bos.write(buffer, 0, read);
toBeCopied -= read;
}
bis.close();
bos.close();
// Wrap the request in a
FileUploadHttpServletRequest for further processing.
chain.doFilter(new
FileUploadHttpServletRequest((HttpServletRequest)
request, bodyData), response);
Thanks
Vijaya
