<section name="Using FileUpload">
<p>
Your application should detect whether or not FileUpload should be
invoked, based on the HTTP method and the content type of the request.
</p>
<p>
Assuming that you have decided that FileUpload should be invoked, you
might write the following code to handle a file upload request:
<pre>
// Create a new file upload handler
DiskFileUpload upload = new DiskFileUpload();
// Set upload parameters
upload.setSizeMax(MAX_UPLOAD_SIZE);
upload.setSizeThreshold(MAX_MEMORY_SIZE);
upload.setRepositoryPath(TEMP_DIR);
// Parse the request
List items = upload.parseRequest(request);
// Process the uploaded fields
Iterator iter = items.iterator();
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();
if (item.isFormField()) {
processTextParameter(request, item);
} else {
processFileParameter(request, item);
}
}
</pre>
