Subject Re: FileUploadBase.UnknownSizeException
Date Tue, 17 Jan 2006 18:32:38 GMT
here's an update on this problem: tells me that their implementation of javax.portlet.ActionRequest.getContentLength()
is currently hard-coded to return -1 ... still talking to bea to try to understand why...
anybody experience the same thing? i would think that if bea, a leading portal provider, has
a problem with this, then it must be a tricky problem to handle??
if any case, i would recommend the following change to the fileupload code:
do not check the request content length if the maximum file upload is set to -1 (meaning no
i believe fileupload checks the length in order to then check that the length is not greater
than the maximum...
this change, along with portlet setting file upload max to no limit (set to -1) in the PortletFileUpload
instance, would provide a workaround for portal implementations that return an unspecified
request content length

That depends. If the request does not include a content length header, then
FileUpload is working correctly. It cannot handle multipart requests unless
the content length is specified. There is an existing enhancement request to
add support for this case. However, this seldom comes up with browser

If the request _does_ include a content length header, then there might be
an issue. You should also ensure that the request has not already been
parsed by some other code before it reaches your code.
