Introduction
• What is the Project?• Integrating Drupal with SDA

Limitations of existing system• Inter module communication
• Has complex and huge modules: intertwined, cannot be separated with Liferay 5.2.3 used by system
• Current system uses some of them e.g. out of 60 3-5 are used - consumes resources (memory, processor, hardware resources, software resources)
• Does not have boundaries between organizations • Passing parameters to multiple portlets• Session management• Very difficult to upgrade to the newer versions• Does not have clean URL

Why we choose Drupal?
Still on the process of studying the feasibility of whether Drupal can replace LIFERAY?
SDA

Why we choose Drupal?Technical motivations:
• Drupal can solve the above limitations of LIFERAY:
• Provide boundaries between organizations• Passing parameters to multiple portlets• Especially upgrade to new version

Why we choose Drupal?Technical issues:
• And more than that, Drupal fulfills other requirements of SDA that LIFERAY can not
• Support group (Organic group)• Time to start and build a module is pretty
quick• Support Java backend: standardize API -
XMLRPC • Very highly scalability and load balancing
support

Why we choose Drupal?Non - Technical motivation:
• Drupal become more popular (Top 3)• Big organizations/firms are using Drupal
• Whitehouse• US Department of Commerce• Continental Airline and United Airline Merger• Intel
• Tietronix customers (including NASA) are switching to Drupal
• Drupal – A free open source tools• Strong community including paid services

System Architecture
Provide an UI to interact with the system
Include logic to present data to the users
No business or data access logics
PHP/HTML/JS/CSS
SDA Presentation - Drupal

System Architecture
Provide an interface for Drupal to interact with SDA
Drupal plays XMLRPC client
SDA backend plays XMLRPC Server
Web Services – XMLRPC
SDA Communications - XMLRPC

Challenges and Pros/cons of communication Techniques
Challenges: • The current implementation uses
Liferay, which supports Java• Drupal is PHP based and thus its
integration with the backend Java business layer is a tricky part
• There are two ways to achieve that:• Web Services (XMLRPC)• PHP/Java Bridge

Challenges and Pros/cons of communication Techniques
• What is XMLRPC?
• What is PHP/Java Bridge?

Challenges and Pros/cons of communication Techniques
To choose between these two options we came up with some evaluation criteria

How we are achieving the goals
• Implement XMLRPC
• Build custom modules in Drupal to replace the modules in Liferay and act as XMLRPC client
• Build a custom class on top of SDA’s core modules and act as XMLRPC server

SDA Communication Module
• This module will act as a communication layer between back-end SDA and its presentation layer
• This module resides on top of SDA’s core java modules. This module contains a class called XMLRPCServer.java
SDA

XMLRPCServer.java
• XMLRPCServer.java contains following three methods: • XMLRPCServer • GetInitialProcessDetails • GetProcessDetails

Future work/ summary• Analyze the possibility, pros and cons, and
personnel skills for integration of SDA with Drupal over the current open source CMS like Liferay
• Implement two SDA modules Lifecycle, My Worklist (J2EE based) in Drupal
• Write the publication paper• More inclined to industrial case study• Focus on issues like migration, integration, use
of multiple languages, and how to deal with legacy system
