How to generate a Java call graph, Eclipse based solutions

I had exactly the same problem, so I 've written the java-callgraph suite of tools. Using it, you can create both dynamic (runtime) call graphs and static call graphs, provided that you have the program's and its dependencies' jar files.


Getting callstack

1) If you can debug the application simply put a breakpoint (double click over the left margin of the code) and wait it to stop. Go to Debug Perspective if you're not there, and open the Call stack View/Panel. It has the call stack :)

2) If you want to print this stack trace somewhere use an Exception:

Exception aux = new Exception("I'm here"); // not for throwing!
aux.printStackTrace(); // if you want it in stdout

or

Exception aux = new Exception("I'm here"); // not for throwing!
StringWriter sw = new StringWriter();
aux.printStackTrace(new PrintWriter(sw));
String result = sw.toString(); // if you want it in a string

Obtaining method references

You can obtain all references to a method by right-clicking, References, Workspace. It will search all callings in your current open projects. Very very useful.

Profiling an app

(thanks those who had answered the profiler option)

Eclipse TPTP provides profiling:
