In Appfuse, we don't use servlets. I am using struts where Action classes
extends BaseAction class. Another question: why the pics are in "admin"
path?
One solution that worked for me is that I saved the pics in a public folder
(accessible by direct url). Then the Action class sends the path of the pic
to jsp, and that path is saved in database. Next, jsp just points to that
url and the pic is shown. Clearly, it doesn't allow us to set privacy
settings to pics. Ad hoc method to fix this is to set the filename something
long and messy, so it is not easy to remember/guess.
Cheers,
Amit
