Final Year Project


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.

Please Refill TVs in all my warehouses


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


Reliable


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

x
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

x
We needed to patch some source files to use the real
local JNDI names to get things working

x
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

?C
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)

x
But would HSQL behave well in real situations?(Doubt,
implies Not reliable)

x
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
