+===========================
+
+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:

+
+In the second command window
+----------------------------
+1) go to mortgage-loanapproval directory
+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
+run:

+
+If the loan is disapproved, you will see the following displayed in the command screen where
+mortgage-loanapproval is run:
+
+Buildfile: build.xml
+run:
