SERVICES Hi everyone!

I'm developing a concept for sending a XML-file to a database with 
SOAP. These XML-files are to be stored in the database and should 
also be available for other individuals to download. The XML-file to 
be sent comes from an ERP-system so the SOAP Client has to be 
integrated with the ERP-system. In SAP this can be done through BAPI, 
in Microsoft Exchange and Office through COM and DCOM, in Unix 
applications with COBRA and EJB with RMI.(or ?) 
I've found a lot of information in Internet about sending 
request/response messages to a web server, but not much information 
about sending SOAP messages with or without attachments to a database 
for storage. I'm not going to code the system myself, but present a 
concept. I was thinking about using a 4-Tier architecture looking 
like this:
< 1. Presentation - a SOAP client > 
------------------------------------------ Firewall
< 2. Web server - Security measures - Microsoft Web Server IIS or 
Apache > 
------------------------------------------ Firewall
< 3. Application server - SOAP server - BEA WebLogic or IBM 
WebSpehere> 
< 4. Database - SQL> 

Is that ok? Suggestions are appreciated.

Can someone tell me:

1) Where I can find more information about the basic steps I have to 
perform? As said, I will not develop the system myself, but present a 
concept for how to do it. Haven't found any good information about 
integrating a SOAP client in an ERP. 

2) if it's better to send a XML-file embed in the SOAP message or as 
an attachment? The XML-file is quite small.

3) can this be considered a web service? 

Thanks in advance!

Marcus
