You need to read the docs on WOFileUpload but here is a rough example:
upload : WOFileUpload {
filePath = fileName;
bufferSize = 2000;
size = 20;
outputStream = byteArray;
}
// variables for the data displayed on screen, submitted into the form
public String fileName;
public ByteArrayOutputStream byteArray = new
ByteArrayOutputStream(1024*1024);
I think “filePath” is somehow mandatory even if you don’t use it.
Basically you are dealing with a component that has been extended over the
years (by Apple) that has grown up and worked around some problems in the early
days of the web. In the original HTML 1.0 days I think you really only could
have 1 image and it must be last. But with a newer parser and some more
maturity, it is possible to stream any number of large binary files and in any
order if you “stream” them. That’s about the best I can do for a brief answer
that is not entirely factual but relatively close to the truth.
