Hi Gilles and All,
Well I am still struggling with this. Gilles, you mentioned that the
"boundary" value might be picked from some library by Zope. But I guess (but
not sure) that the request is created by the client (browser) ie the
boundary value is also entered by the browser. If not then Zope should send
some boundary value somehow alongwith the FORM html code.
I have added the "Java Code" at the bottom of the page. This code works fine
with another Form submission form written by me but not with the Zope form
as mentioned in the code. Could you or someone help me in detecting out as
what is the problem.
Thanks
