Help - Am I going down the garden path?

[Keith Chadwick]

Couple of questions for all of you.

My web pages are currently using my web services to fetch all of there data
as xml. The xml is placed in a MSXM4 object then rendered client side with
xslt. This works fine, now getting the data back.

I would like to update the client side xml with the changed values from the
form, easy enough. Then send that data back to the web service. So here
are my questions

1. Can I use the XMLHTTP object in JScript to create a post back to to a web
service?
2. If I wish to embed the xml into the XMLHTTP.send method call do I need to
start using soap?
3. If I am using soap do I need to create a proxy of the webservice in order
for the WSDL to be created?
4. If I am using soap, can I embed a document that the user has requested to
be updated. Can this be placed within the soap packet along with other xml?

Not looking for how you do it simply want to find out if I am on the right
path or not with some links. Been reading all weekend both books and
on-line and nothing seems to give a clear answer or example. The reason I
am using web services to post my data is because at a later date the
services will be made available to 3rd party vendors, right once use many
idea!

Any thoughts would be appreciated.

Cheers

Hi Keith,

Answers in-line:

1. Can I use the XMLHTTP object in JScript to create a post back to to a web
service?

Yes. You have to carefully craft the response so that it is consumable by
the method you expose as an ASP.net web service, but you can use pure XML
on the client.

2. If I wish to embed the xml into the XMLHTTP.send method call do I need to
start using soap?

In general, yes. SOAP is required for the ASP.net web service
infrastructure to work.

3. If I am using soap do I need to create a proxy of the webservice in order
for the WSDL to be created?

No. The WSDL is a server side thing and not related to the web service
caller code - but it is used to create a caller-side proxy by certain tools.

4. If I am using soap, can I embed a document that the user has requested to
be updated. Can this be placed within the soap packet along with other xml?

The SOAP message needs to map directly to the method requirements on the
service side. You will need to also comply with SOAP rules - you can add
XML in headers, and you can have a single element child of Body.

I hope this helps.

Thanks Dan,

After two days of exhaustive struggling I have finally managed to build the
soap package and submit it. Like anything it is easy once you do it but
getting the first one figured out can be a real nightmare.

I have put another post on the newsgroup regarding dealing with the
submitted xml. I hope you or someone respond to it soon.

cheers
