Hi All,
I'm new to web services and just started learning the basics i.e. SOAP,
WSDL.
*According to my understanding:*
The *Client *sends a SOAP request to the *Receiver*.
The *Receiver *then finally sends the SOAP response to the *Client*.
But in books its mentioned :
All SOAP messages start with the initial sender(*Client*), which creates the
SOAP message, and end with the ultimate receiver(*Web Service*).*(OK)
*A SOAP message travels along the *message path *from a sender to a
receiver.*(DOUBT)*
As a SOAP message travels along the message path, its header blocks may be
intercepted and processed by any number of *SOAP intermediaries* along the
way. *(DOUBT)*
A SOAP intermediary is both a receiver and a sender. It receives a SOAP
message, processes one or more of the header blocks, and sends it on to
another SOAP application. *(DOUBT)*
The applications along the message path (the initial sender, *intermediaries
*, and ultimate receiver) are also called *SOAP nodes*.*(DOUBT)*
*I'm having a following doubt:*
Why we are having the *SOAP Intermediaries* ?
Since we only have a Client and the Receiver(*Web Service*).For example,
I've a *Java Client* that invokes a method of the *Web Service*.
Please help me in understanding the core concept as well as the context in
which this *SOAP Intermediaries *are being talked about.
A practical example would be great.
Thanks,
Nirmal
