I?m very glad to see the topic of s:upload being discussed, because I too am
having problems. I have managed to get s:upload to do exactly what I want with
just one file upload box on a page. But my goal is multiple file upload boxes
on the same page. What im doing is linking the data and fileName attributes
directly to an entity bean that contains my getters and setters. In the getter
method for a the column in my db where I want to store the name of each
filename I added some code to write the file to a directory on my server then
return the file name. pretty simple I thought. But running to problems I don?t
understand
1. the only name I can give the fileName attribute is fileName? I know,,,
sounds bazaar. But it seems to be the case
2. if I add the second upload box with different targets, the first box
fileName will persist fine,, but and a blank file is written to disk,,, but
content is null.
Any help or criticism will be greatly appreciated.
Using seam 1.2.1 and jboss 4.0.5
