A Brief History of Abeans

• 6 years of continuous development• @ ANKA, DESY, ESO, RIKEN, SNS, DLS, GSI,

SuperSOR, UVSOR, ...

Release 1– A wrapper for CORBA to make Java clients

Release 2– Plugs for different CS are introduced

Release 3– Professional, reusable GUI components– Plugs, Models, Services



Basic Concepts

• Model: Logical containment of CS Objects– Channel, Device oriented

– GIS • Plug: Connection to remote modeling layer

– ACS, TINE, EPICS, UFC• Service: Implementation of shared functionality

– Error reporting, Logging, directory and lookup services

Experience of Using Abeans at Various CS

• ANKA, ESO: ACS CORBA

• GSI: UFC going to ACS CORBA

• DESY: TINE

• Diamond, SNS: EPICS

• SNS: GUI Components



Use of Enhanced GUI Components

• Use Abeans as a library– GUI widgets– Services



Display of Data Quality



Building GUI Applications

• Using NetBeans IDE to build GUI applications



Use of ACS Services

• Most ACS CORBA services lack GUI components

• Example: Remote Logging service of Abeans– Encapsulates ACS CORBA logging

• Part of every Abeans application



Facilitating Upgrade of GSI CS

• UFC, a custom CS will be upgraded to CORBA

• Transition period – both systems have to be supported

• Abeans can use multiple plugs– UFC + ACS



Hierarchies in EPICS

• EPICS is a flat database– Hierarchy: Additional

data are needed• Naming convention,

database, etc.

• Abeans directory service– EPICS plug fills it– Based on JNDI– Cosy Navigator



Reducing Memory Footprint of Java

• Java Virtual Machine Sharing

Platform Independence for DESY

• TINE – applications in Visual Basic• Some people have Sun and Linux. They

have the need to run the same applications

• Abeans are written in Java

• Archive Reader



Archive Reader for DESY



Physics Applications for ANKA



Complex Panels for ANKA



Power Supply Table for Hitachi-Zosen



Vacuum Display Application for Diamond



Object Explorer



Control Desk - Towards "ACS Office"



Conclusion – What are Abeans Really

• A self-contained application framework• Deliver generic applications• A library for

– Communication management– GUI widgets– Services (e.g. Logging)

• Professional development process• Documentation (tutorials, reference manuals),

tests, quality control, support
