    Develop some frameworks for the ePlatform
    Workflow framework, drive users through an application, use a description language very similar to java, generate dynamically buttons definition in XML. Multi applications.
    Chart engine framework customized for insurance, based on Chart2D. Accept a meta description container in XML to read data. Output gif, jpeg, png. Adding a new product is done by dragging a configuration file in a directory. Design/Layout, retrieving data are configured through reusable factories.
    Virtual Transport (VT) framework which provide independancy of protocol (generic client ProcessIF) with the help of plugins: Soap Apache, Soap Axis, socket, local jvm. Calls are driven by controller plugins: load balancing, fault tolerant, Once, firstWorking. The responsability to choose a server among a list is done through load balancers (random, weighted round robin (WRR), round-robin (RR), least weight connection (LWC), least connection(LC) ). The error handling is done with the help of failures handlers (single, multiple failover, rethrow). Discovering of webservices and also servers is done with a load balanced and redundeant pool of UDDI registries (use also VT). Exception are dynamically rendered through exception renderer. The internal design is highly extensible(60 pages of documentation- 180 classes, 48 interfaces) - checked exception - 3 caching algorithms - Audit/history in XML - 10 factories.
    Container framework for holding data in bean and E3 for nimius. Automatic marshalling into XML.
