File upload problems

[Azariah Jeyakumar <az...@tumbleweed.com>]

Hi,

We are using the file upload feature of struts heavily. We face the foll
problems:

1. I get "java.io.IOException: end of stream before boundary found!"
intermittently (full stack trace below). Roughly 1 out of 10 or 20 times I
submit the form that contains File upload. I have not been able to identify
a pattern when this exception happens. But I think the exception happens
only when no file is actually entered/uploaded.

To elaborate, my form has several Submit buttons. Only 1 of the submit
button expects the type=file field to have a valid file name. All other
submit buttons dont care about the field. When I click on one of these other
submit buttons, I get the above exception, intermittently.

2. The tag struts:multibox does not work well in a form that has
enctype=multipart/form-data. Only the last checkbox that I selected is set
in the multibox form field. I expect a comma separated list of the value of
all the selected checkboxes. This works in the form if I remove the enctype
attribute.

We use jakarta-struts-1.0-b1.

Thanks
Azariah
