Seam provide a very simple way to process file upload.
There is s:fileUpload to process uploading UI...
Create a Enitity with a @Lob byte field...binding the s:fileUpload data attribute to the field, when the entity is saved, the file is stored into database.
Could you please elaborate with example. Because I'm very new to seam.
If you search a little in this forum you will find examples. Also the seam documentation is a good place to start
