Date Thu, 17 May 2007 20:56:28 GMT

im trying to upload a file using jsp.

a flash application is sending a http post multipart upload to the jsp.

i cant seem to get the thing to work.

when i remove the added code for the commons-fileupload, the jsp runs. when
i put the code in as described on  jakarta website, i get the error outlined
below. does anyone have any ideas or suggestions.
