UploadedFile and getting multiple file uploads?

I've created an XPage with a call to a Java class in the beforePageLoad event that takes over.

In the Java class I want to receive one or multiple file uploads (through a HTML form with multiple file upload controls all with the same name file).

This works:

Map parameters = request.getParameterMap();
UploadedFile file = (UploadedFile) parameters.get("file");

This does not work:

Map parameters = request.getParameterMap();
UploadedFile[] files = (UploadedFile[]) parameters.get("file");

So my questions is: How can I get to more than the first uploaded file from the Java class and loop through and process each of them?

Assuming, your Map parameters contains all UploadedFiles then you can get them all with

for (Entry entry : parameters.entrySet()) {
    System.out.println("parameter: " + entry.getKey());
    if (entry.getValue() instanceof UploadedFile) {
        UploadedFile file = entry.getValue();
        // work with file
    }
}
