JAIDA is a Java implementation of the Abstract Interfaces for Data Analysis (AIDA) and
is part of the FreeHEP library. JAIDA allows programmers to easily
create histograms, scatter plots and tuples, perform fits, view plots and store and
retrieve analysis objects from files. JAIDA can be used for batch processing or with a GUI.
JAIDA reads and writes AIDA compliant files and can access data from ROOT, HBOOK/PAW
or SQL databases. Access from C++ uses the AIDAJNI adapter. JAIDA includes JMinuit,
a complete port of Minuit to Java. JAS3 uses JAIDA providing a full featured GUI.

WIRED4 is a generic Event Display displaying 2D/3D views of HepRep events.
As plugin module in JAS3 it has full interactivity, such as scaling,
rotation and hiding. Recent extensions handle picking of elements to show
detailed information and interactive cuts to hide details.

The AIDA tag library (AIDATLD) is an open source suite of custom tags that provide access
to JAIDA from J2EE applications and JSP pages. It can dynamically
create high quality physics and astronomy plots and providing access to
histograms and Ntuples stored in any AIDA store, including ROOT files via (x)rootd,
from web applications.

This software is used by several experiments and collaborations, including
BaBar, GLAST, and Geant4. Experience of using this software and new
developments will be presented in the talk. In particular, a wide ranging suite of web
applications developed using these tools for the GLAST experiment will be described.
