Development Highlights

The Charting Tool application consists of 3 parts: Flex UI, Java Server and the Data sources. In addition to these, there are data scripts running to load data from various external sources into the system’s database. An email reader runs to fetch data from the system’s link.


The application is hosted on 2 cloud server instances with Rackspace

The heart of the application is the Tomcat app server. The application is split into 2 web mapplications ROOT and Charting Tool. The code for the client’s website is served by the ROOT web app (/usr/share/apache-tomcat-6.0.29/webapps/ROOT) and the services for the Charting Tool are all handled by the Charting Tool web app (/usr/share/apache-tomcat-6.0.29/webapps/ChartingTool). The Charting Tool appuses Spring and Hibernate frameworks for business logic wiring and database access.

The application follows a Service Oriented Architecture and the Charting Tool exposes multiple services in the Java Services layer. All remote method calls originates from the Flex UI and are processed by the Blaze DS Layer(http://opensource.adobe.com/wiki/display/blazeds/BlazeDS) which then utilizes one or more Java Service. Calls such as login, post chart, subscribe which originated from the HTML pages are processed by the JSP/Servlet layer which further uses the Java Services.

The Delegate layer has the business logic and uses the Data Extractor layer to either get Hosted Data from the Elmwood database server (eg. iVol, COT) or use specialized data fetchers and parsers for Non Hosted Data (Internet search trends, FRED, DDF) or fetches data saved on the file system used by the user uploaded


Email reader task is configured as a 4 hourly crontask in the Charting Tool web app using Spring Scheduling. It uses IMAPS to check the email id to extract all .xls files for data sources such as Rail Data and other adhoc data sets such as Survey, Rig etc. These are sent in a pre-decided .xls formats to the pre-defined id, parsed and then loaded in the system’s database
