Java applications are profiled/traced using the -XrunTAU command-line parameter as shown below:

% cd tau/examples/java/pi
% setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:/home/tau/
solaris2/lib
% java -XrunTAU Pi

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