Challenge
Provide an end-to-end loan origination, pricing,
pre-qualification and closing tool for SPHL's partners.
Solution
Use industry standard MVC web development framework to
provide a cross-platform, standards based web application,
Streamline.
Story
Faced with the task of providing a web application that had
to collect and store data as well as interface with third
party loan origination systems, Java was the natural choice.
Write once, run anywhere combined with a rich set of
established API's make Java perfectly suited for difficult
integration tasks. CloverLink Systems decided on a MVC
architecture for the site using the Webworks 2 and Xworks 2
framework for the site itself, industry standard JDO as the
persistence mechanism and a wide array of other Java tools
to provide the glue and support mechanisms, including Joram
JMS for guaranteed asynchronous processing of back end loan
origination system requests, picocontainer for configuration
and service dependency resolution, FOP for PDF document
generation and Freemarker and Velocity for template driven
views and data. CloverLink used agile development techniques
including test driven development, frequent peer code review
and extreme programming to deliver the solution to the
client on time. CloverLink's portal application tied the
development process together to give the client an up to the
minute view of the development process, issue resolution,
test results and build status.
The SPHL web application is a complex interface which
presents three faces to the outside world: a realtor partner
view, a mortgage manager view and and administrator view.
All of these views are provided using an advanced role based
authentication and authorization scheme and template-driven
view management system made possible by the Webworks/Xworks
MVC framework. Once signed up, the realtor users are able to
make loan applications on behalf of their consumer clients
and track the progress of the loan approval from application
through loan product selection and final loan funding by
SPHL partner institutions. The entire process is under the
control of the administration and mortgage manager users
using an advanced administration interface.
Perhaps the most difficult challenge was integrating with
the Gallagher GFS loan origination system. CloverLink had to
be extremely creative in working around limitations of the
GFS platform to provide a web-service view of the GFS api.
With CloverLink's integration ?glue? in place, SPHL's
partners are now able to take advantage of the advanced
mortgage loan pricing engine that GFS provides. SPHL can
itself make use of the GFS system in novel ways, including
custom clients and other web services built on top of the
interface that CloverLink wrote.
The CloverLink solution was written with extensibility and
reuse in mind. All components and services are interface
driven and can be swapped with alternate implementations if
desired. The integration with SPHL loan funding partners is
completely extensible. The system is able to handle
xml-based funding solutions, RPC based, what have you ?
anything the Java platform supports, the SPHL web
application can talk to.
The SPHL Streamline website presented a challenging
integration problem to CloverLink. But the correct selection
of implementation platform and tools made it possible for us
to deliver the site on time with all specified
functionality. These same choices will make it possible for
CloverLink to adapt and evolve the solution to SPHL's
changing needs in the future. |
