                                          throws IOException

Method used to stream content from a multipart request (either from servlet or portlet request) to given StreamVariable.

This method takes care of locking the session as needed and does not assume the caller has locked the session. This allows the session to be locked only when needed and not when handling the upload data.

Overrides:

doHandleSimpleMultipartFileUpload in class com.vaadin.server.communication.FileUploadHandler

Parameters:

session - The session containing the stream variable

request - The upload request

response - The upload response

streamVariable - The destination stream variable

variableName - The name of the destination stream variable

owner - The owner of the stream variable

boundary - The mime boundary used in the upload request

Throws:

IOException - If there is a problem reading the request or writing the response
