In the context of building a new generation ERP runtime system, fully metadata driven, and based on a Domain Specific Language, design and implementation of a full authorization engine in Java for complex integrated systems using WebServices – EJB – Java Generation.
- Definition of a Role and Rule based Authorization engine.
- Modify generated code to integrate the security request in the core system code for a maximum security level.
- Definition of a Domain Specific Language defining the Security rules used by the engine to evaluate Authorization request and generation of the Java classes.
- Definition of an Eclipse based set of tools to edit/define/customize the security definition, integrated in a complete application development tool for the new ERP runtime system.
Main Points :
- Strong exposure to Lawson Security Models (Classical and Landmark)
- Work with fully Metadata driven architecture
- Creation of Domain Specific Language : parsing and Java classes automatic generation
- Integration in Application Servers (EJBs and Web Services, WebSphere, JBoss and Tomcat)
- Development of a Rapid Application Development tool in the Eclipse Framework

Design and implementation a new CORBA architecture for a data acquisition real time system for MudLogging, based on the data server developed earlier.
The aim is to manage all the server-side modules in a same way.
- Design administration and diagnosis procedures
- Design CORBA interfaces using the procedures to standardize the behavior of all the servers regarding administration tasks
- Implement this interfaces in the 30 different CORBA servers, each one manage a particular type of data.
- Design a GUI to allow the users to use the procedures, diagnoses a problem and try to solve it.
- Changing ORB from Visibroker 3 to JavaIDL, and using of POA instead of BOA in all the system.
- Design and implement a solution to launch the different servers in different JVM other the different PCs used.
- Design and implements a set of tools and different clients for this server (User applications, Scripting tools, computation processes, …)
Main Points :
- Interfaces in distributive system
- CORBA, JavaIDL, System programming in Java

Design and implementation of a Real-Time Database Server.
- In a CORBA architecture (Visibroker), Real-Time multi-threaded server implemented in C++ under Windows 2000.
- Starting with different modules existing in a prototype and global rewriting of these modules in a way to increase performances and to integrate new high-level functionalities.
- Design and implementation of various Java clients for this server
- Then Design and implement this server in Java 1.4.
Resulting Server :
- Full 100% Java Data server.
- Tested with 2000 concurrent requests.
- Manage storage in binary files, memory cache system, and subscriptions functionalities to alert clients when new values are entered in the database.
- High level data processing
Main Points :
- C++, Java 1.1, Java 1.2 et Java 1.4 - UML
- Multithreading and memory profiling in Java and C++
