I had this problem and it was because I was using the 'normal' way of getting
the input parameters from the request object (eg. request.getParameter
("name")) instead of traversing the items from the multipart request.
If ServletFileUpload.isMultipartContent(request) returns true then you need to
get the fields via the upload.parseRequest(request) method.
eg:
// Check that we have a file upload request
boolean isMultipart = ServletFileUpload.isMultipartContent(request);
if(isMultipart)
{
// Create a factory for disk-based file items
DiskFileItemFactory factory = new DiskFileItemFactory();
// Set factory constraints
factory.setSizeThreshold(1000000);
factory.setRepository( ConfigServlet.getTempDirectory() );
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
// Set overall request size constraint
upload.setSizeMax(10000000);
// Parse the request
List<FileItem> items;
try {
items = upload.parseRequest(request);
for(FileItem item : items)
{
if (item.isFormField()) {
String name = item.getFieldName();
String value = item.getString();
query.put(name, value);
}
else // file object
{
// do stuff for file request
}
}
} catch (FileUploadException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else
{
query = new TreeMap<String, Object>();
Map tbl = request.getParameterMap();
query.putAll( tbl );
}
Hope this helps you
