When using the vaadin upload you should be able to use a ByteArrayOutputStream instead of a FileOutputStream.

So just use the sample from the book of vaadin but use a ByteArrayOuputStream instead.

When the uploadSucceeded method is called, you take the ByteArrayOutputStream, convert it into a string (Beware of the correct encoding) and set it as the value of your TextArea/Field.
