Mobile Phone Stock Trading for MIT
Innasite
has developed a middleware product based on the Open Financial
Exchange (OFX) standards to enable share trading for mobile
phone users through the Morocco Stock Exchange
The complete share trading operation can be divided into the
following steps: .
1.
User sends a transaction request through the mobile phone
to the Financial Services Provider (FSP). FSP captures user
actions and converts them into an OFX compatible request
for further processing by the OFX Servers. The FSP also
serves as the WAP gateway.
2. OFX server accepts the OFX requests from the Financial
Services Provider and convert the requests to a Java object
using the Java Architecture for XML Binding (JAXB). The
Java objects built at run time using the JAXB are then converted
into Enterprise Java Beans (EJB). The EJB components are
deployed on an Oracle 9i Application Server platform. The
backend database used for persistent storage is Oracle 9i.
3. The Java Objects are then delegated to the internal process
servers based on system requirements. The internal process
servers are divided into the Front Office, the Middle Office
and the Back Office. The internal process servers are responsible
for work-flow checks, validations and other processes before
the OFX request is sent to the stock exchange for completing
that request.
4. The OFX server communicates with the stock exchange through
Java Messaging Service (JMS). The request is converted into
stock exchange compatible format and put in the message
queue. The same process is followed the other way round
for responses from the stock exchange.
Technology
used:
Sun
Solaris, Oracle 9iAS, Oracle 9i database, EJB & Java
Objects using JAXB, OFX adapters, Java - XML based adapters,
Apache Soap for SOAP-RPC calls, SMSSE V2 SMS Messaging service
Engine, Apache ANT, and Apache Log4j
