I can't find any references to Java stuff at the link you mentioned. By the way, the code is C, not C++.

I'm not sure if that is what you meant, but integrating Java and C/C++ code involves the Java Native Interface (JNI). I was once engaged in heavy JNI work about 6 years ago at college but have almost entirely forgotten most of it, because I have forgotten most of C/C++ myself.

The coverage of JNI has been stripped of the Sun Java tutorial for many years, probably due to lack of interest. If you want to find more information, you will need to search for older documents. I dug this up in an early version of the Java tutorial:

Integrating Native Code and Java Programs

Good luck, because it is very easy to crash the JVM with JNI.

jstack

jstack(1)						      General Commands Manual							 jstack(1)

NAME

       jstack - stack trace

SYNOPSIS

       jstack [ option ] pid
       jstack [ option ] executable core
       jstack [ option ] [server-id@]remote-hostname-or-IP

DESCRIPTION

       jstack  prints  Java  stack traces of Java threads for a given Java process or core file or a remote debug server. For each Java frame, the
       full class name, method name, 'bci' (byte code index) and line number, if available, are printed. With the -m option,  jstack  prints  both
       Java  and  native frames of all threads along with the 'pc' (program counter). For each native frame, the closest native symbol to 'pc', if
       available, is printed. C++ mangled names are not demangled. To demangle C++ names, the output of this command may be piped to c++filt.

       NOTE - This utility is unsupported and may or may not be available in future versions of the J2SE SDK.  jstack is not  currently  available
       on Windows platforms or on the Linux Itanium platform.

PARAMETERS

       Options are mutually exclusive. Option, if used, should follow immediately after the command name.

       pid	      process  id  for which the stacktrace is to be printed.  The process must be a Java process. To get a list of Java processes
		      running on a machine, jps may be used.

       executable     Java executable from which the core dump was produced.

       core	      core file for which the stack trace is to be printed.

       remote-hostname-or-IP
		      remote debug server's (see jsadebugd) hostname or IP address.

       server-id      optional unique id, if multiple debug servers are running on the same remote host.

OPTIONS

       -m	      prints mixed mode (both Java and native C/C++ frames) stack trace.

       -h	      Prints a help message.

       -help	      Prints a help message.

SEE ALSO

       pstack(1) c++filt(1) jps(1) jsadebugd(1)

KNOWN BUGS

       Mixed mode stack trace, the -m option, does not work with the remote debug server.
