Hi,
I have
just finished a short project that uses SOAP but also requires encryption,
digital signatures and binary transfers. Since these components of SOAP
standard are not well supported I used a similar technique to Jerry. I wrap all
data up into a xml string and then apply any necessary encryption to the string
as a whole. For binary transfers I use an Hex encoding rather than base64. I too
have encountered size limitations leading to a need to make multiple
requests to the SOAP server. A better approach would involve a single request
and then asynchronous message responses pushed by the SOAP server. As far as I
can tell this is not possible as yet.
This
packet wrapping approach has worked well for us but does require that both
ends of the connection understand the wrapping techniques used. This
inevitably leads to greater coupling, something that Web Services try to
avoid.
Darren.

Subject: Size limits on SOAP messages
Hello,
I have encountered a
size limitation of 1.4 megs in my payloads. I am using the Microsoft Soap
Toolkit version 2 low API's to send a payload to an Apache Soap 2.2
implementation on Solaris 8 running iPlanet Application Server 6.0 SP3. I go
around some file limitations mentioned at this site by encoding my data in
base64 and treating it like a string on the server. I am convinced that it is
best to simply exploit this technique and write an architecture around
compressing and breaking large payloads into packets and managing those
packets on both client and server.
In considering this
architecture I am thinking of concepts already applied on the News Servers and
News Readers. A mature publisher/subscriber model with peer to
peer replication has a strong appeal. If only there was a way to administrate
user privileges and hide channels then we'd really have something interesting.
Has anyone implemented SOAP on top of NNTP and integrated that type of
service with a web server?
