Mortgage Loan Approval Demo
===========================
This demo was used as an example in the java developer journal article: http://jdj.sys-con.com/read/325183.htm.
The demo consists of two modules:
mortgage-loanapproval: provides the business logic for loan approval.
mortgage-creditcheck: handles credit check requests. This is a java component exposed as a webservice running on the embedded Tomcat.
Please check mortgage_assembly.png file that is located in this directory for a high level view of the demo.
Here is what happens when you run the demo. A loan approval request for customer with id 111-222-3333
gets initiated when mortgage-loanapproval application is run. Depending on what the 'imaginary' credit
status of this person is, the loan gets approved or diapproved.
You would need two command windows to run mortgage loan approval composite. The order in which the
applications are run is important. Run mortgage-creditcheck first since mortgage-loanapproval is dependent on
it's service.
In the first command window
---------------------------
1) go to mortgage-creditcheck directory
2) ant compile
3) ant run
You should see the following displayed:
Buildfile: build.xml
run:
[java] Starting the CreditCheck Service...
[java] log4j:WARN No appenders could be found for logger (org.apache.axiom.
om.util.StAXUtils).
[java] log4j:WARN Please initialize the log4j system properly.

In the second command window
----------------------------

2) ant compile
3) ant run
If the loan is approved, you will see the following displayed in the command screen where
mortgage-loanapproval is run:
Buildfile: build.xml
