Huge opportunity to work with Atos Origin
India (regarded as one of the leading brands
in IT industry worldwide)
Curiosity regarding how the IT industry
works, as majority of the jobs are IT oriented
Willingness to learn new technologies and
accept new challenges
Software Applications are an integral part of
our lives

Scenario : Retailer offering TV sets to Consumers
(TV delivery being the supply chain module)
The application should generate tasks for various
departments automatically (Automation)
To fulfill orders the Retailer has to manage stock
levels in warehouses ( 3 Warehouses considered )
When an item in stock falls below a certain
threshold, the Retailer must restock the item
from the relevant Manufacturer’s inventory ( One
Manufacturer, ‘Sony’ )
In a simple way, our web-application handles the
part after an order bill is generated by websites
like eBay, Amazon, etc.
I have only 3!
Please Refill TVs in all my warehouses
Warehouse A
Send 4 Tvs

A recent study found that supply-chain
problems cost companies between 9 and 20
percent of their value over a six-month
period
Effective supply-chain software tools could
save companies billions of dollars
No open source application available for
Supply Chain Automation
Java based- hence can be accessed anywhere

The business process was analyzed and a
flow diagram was designed on paper
Lets have a look at the Flow Diagram





How to implement workflows? A very powerful
opensource tool,jBPM comes to the rescue
The flow diagram was then implemented using
the Graphical Process Designer for jBPM
configured in Eclipse IDE
jBPM needs Database,MySQL was configured as
the database for jBPM
jBoss AS was configured to run/host the jBPM
process
Dynamic Web Project was created for UI pupose

Which version of jBPM to be used?
◦ jBPM 4 vs jBPM 3
 jBPM4 tools are only half finished and quite buggy
 The original 'brain' of JBPM has left Redhat and is now
working on a competing open source API under the
name of 'Activiti‘
 Apparently Redhat also already has JBPM5 in
development;JBPM4.x is given up for lost for now and
the focus for the tool development will be on JBPM5
 All is fine and well, but we all want is a working JBPM
API that DOES have functional tools. So we stick with
old JBPM 3.2.X, which has served well

Configuring jBPM 3.2.x with jBoss 5.0
◦ Fixing jbpm-enterprise.jar
 The main problem we needed to fix here is the way
that the JNDI lookups are done - it tries to use the
java:comp/env space, which is off-limits unfortunately
 We needed to patch some source files to use the real
local JNDI names to get things working
 Luckily we know these JNDI names; they are defined in
the jboss.xml descriptor file
◦ Configuring jBoss Data Source file for MySQL

Which database to be used?
◦ Although MySQL was directly suggested its important to
know why we need to use MySQL when default
configuration with HSQL is easier than configuring
another database with jBPM
◦ HSQL vs MySQL
 Hypersonic is a memory-resident test database. The fact
that all data is kept in memory accounts for the speed
difference.(HSQL is faster)
 But would HSQL behave well in real situations?(Doubt,
implies Not reliable)
 MySQL is a free 'real' database in the sense that it is used in
many production systems and is tested to be reliable.

We have released our project under Eclipse
public license (Open source license) on
Google Code
The project has got 31 download hits already
Source code hosting with SVN
◦ The project we developed serves on a smaller scale
and has a large scope of development to serve the
industry
◦ Keeping this in mind we have hosted the project on
