Web service that is able to receive a xml "POST" and process it

[Jay]

Hello all,

I was wondering if someone can point me to a tutorial that show me how
I can set up a web service that can listen for me to send a POST from a
client? like so

Client sends http POST to http://www.mysite.com/processTheRequest. The
data being sent across is XML like so "<request><data>alot of text data
that I will manipulate and save to the sql database</data></request>"


the serverside should have some function to receive this data.

receiveData(object sender, events e)
{
manipulate the data and respond to the post with
"<response>success</response>"
}

Jay,

That's what a webservice does by default. Just create the webservice method
and have it accept an xml parameter. XML is easily converted to and from a
dataset which is safe for sending in a webservice (data must be
serializable). In .NET 2.0 DataTables are also serializable. So you could do
something like this:

<WebMethod()> _
Public Sub XMLAcceptor(ByVal xmlDataset As Data.DataSet)

End Sub

what if I wanted to send xmldata as a string (that is formated in xml),
receive this string and do a

xmlDocument.Load(xmldata);


any examples or step by step tutorials?

 

[S. Justin Gengo [MCP]]

Jay,

You may certainly send the xml as a string just use ByVal xmlString As
String instead of the dataset.

Then load the string into an xml document like this:

xmldoc.LoadXml(sXML)

After that there are plenty of examples like this (do a google search on
"asp.net xmldoc" to see plenty more):

so I get to the point where I created a web service and it comes up to
this page when I push play. I can also click on jaytest and it will
take me to an invoke page... but when I try to send a transaction from
another application(that I have sent thousands of WebRequest Post to
our linux jboss server) it does not work.
