maximum size of a document for a doc/lit ws

[Dario Di Minno]

Hi axis users,
have you got an idea of how much can be big in MB a document transported 
in a message of a doc/lit web service?

I'd like to know it because I have to decide if a web service has to 
transport data as attachment or not.

(When I tried message style web services I experienced many "out of 
memory error" with large (several MBs) documents).

Thank you.
Dario
