Hello,
I am making a forum where people can upload files to be shared. I can't make file
upload work whereas I am in a very classical environment :
seam 1.2.1 CP1
jboss eap 4.2.0
filename and bytearray are seen as null in the SFSB
I have seen some people having quite the same problem but none of the case corresponds to
my problem.
it might be silly but ....i am stuck
here is the web page :
