PULL Model (Receiving Messages by the Client System)

16-9

PULL Model (Receiving Messages by the Client

System)

In the PULL model, the sender application of the server system (sender server) sends a SOAP message

and the receiver application of the client system (receiver client) receives the SOAP message to

process it.

Table 16-2 lists the items that must be agreed upon between the applications.

Table 16-2 PULL Model

PUSH sender (client system) setting item PUSH receiver (server system) setting item

Message type ID Message type ID

Receiver client ID Receiver client ID

Sender server ID Sender server ID

Key pair of the sender server Public key obtained from the sender server

Public key obtained from the receiver client Key pair of the receiver client

URL with which the sender server of the PULL

model is registered

URL with which the sender server of the PULL

model is registered

Each ID must be agreed upon in advance before specifying it for registration of the Web service. To use

the non-repudiation (signature option) function, it is necessary to prepare a key pair to be used for

SOAP digital signature for each side and to exchange the public keys of the sender server and receiver

client in advance using a file.

It is also necessary to place a sender application and a receiver application separately in the sender

server environment and receiver client environment respectively and to register Web service information

of each application.

Preparing a Key Pair and Public Key Used by the Sender Server

This section shows the procedure for using the non-repudiation (signature option) function.

The examples shown in this section specify commands used in an Interstage certificate environment.

Prepare a key pair for the sender server. The key pair is the same as that for the SOAP digital signature.

An example of command execution for generating a key pair for the sending server is as follows:

scsmakeenv -n serverkey -f filename

Next, prepare a public key for the receiver client. Since the receiver client also needs the public key of

the sender server to use the non-repudiation function, it is necessary to exchange the public key with

each other.
