  Modern beamlines at SOLEIL need to browse a large amount of scientific data through multiple sources that can be scientific measurement data files, databases or Tango [1] control systems. We created the COMETE [2] framework because we thought it was necessary for the end users to use the same collection of widgets for all the different data sources to be accessed. On the other side, for GUI application developers, the complexity of data source handling had to be hidden. These 2 requirements being now fulfilled, our development team is able to build high quality, modular and reusable scientific oriented GUI software, with consistent look and feel for end users. COMETE offers some key features to our developers: Smart refreshing service , easy-to-use and succinct API, Data Reduction functionality. This paper will present the work organization, the modern software architecture and design of the whole system. Then, the migration from our old GUI framework to COMETE will be detailed. The paper will conclude with an application example and a summary of the incoming features available in the framework.

  To build integrated high-level applications, SOLEIL is using an original component-oriented approach based on GlobalSCREEN, an industrial Java SCADA [1]. The aim of this integrated development environment is to give SOLEIL's scientific and technical staff a way to develop GUI applications for beamlines external users . These GUI applications must address the 2 following needs : monitoring and supervision of a control system and development and execution of automated processes (like beamline alignment, data collections, and on-line data analysis). The first need is now completely answered through a rich set of Java graphical components based on the COMETE [2] library and providing a high level of service for data logging, scanning and so on. To reach the same quality of service for process automation, a big effort has been made to integrate more smoothly PASSERELLE [3], a workflow engine, with dedicated user-friendly interfaces for end users, packaged as JavaBeans in GlobalSCREEN components library. Starting with brief descriptions of software architecture of the PASSERELLE and GlobalSCREEN environments, we will then present the overall system integration design as well as the current status of deployment on SOLEIL beamlines.
