Java applications are profiled/traced using tau_java as shown below:

% cd tau/examples/java/pi
% setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:<tauroot>/<arch>/lib
% tau_java  Pi

More information about tau_java can be found in the Tools section of the Reference Guide.

Running the application generates profile files with names having the form profile.<node>.<context>.<thread>. These files can be analyzed using pprof or paraprof.
