The AIDAJNI adapter package allows a C++ program to use the C++ AIDA interface to link with a Java implementation of AIDA, such as JAIDA.
Geant4 can for instance be linked against AIDAJNI, thereby enabling it to use JAIDA to write .aida files which can afterwards be analysed using JAS3 - Java Analysis Studio.
The package is available for the Linux, Windows, Sun and MacOS X platforms using a variety of compilers.
AIDAJNI uses the JNI (Java Native Interface) to access Java from C++ and vice-versa.
