Generating Method Call Diagram in Java Project

I have a source code of a java Project and i want to trace for every method, what method called inside that method.

example:

foo(){}
bar(){}
bar2(){
   bar();
}
foo2(){
   bar();
   bar2();
}

main(){
   foo2();
}

the result will be like:

main
|_foo2
  |_bar
  |_bar2
    |_bar

any add-ons or plug-ins is okay and since it is an internal project of a company, i hope the tools is offline. For the result, it doesn't have to be like that, graph or anything is okay.

Adding some information:

1. I cannot edit the code
2. I cannot run the code
3. but (maybe) i can add them to eclipse IDE
4. The project is either in WAR, EAR, or JAR type

Firstly, If you are use Eclipse as your IDE, then you can right click on a method and choose "open call hierarchy"
then eclipse shows all the methods that call the selected method and all the methods that are called from the selected method .

Secondly We can find it by programming.

ie, by using the eclipse JDT internal classes, these are the same classes used by eclipse to show whose calling the method.

initially we need to importing below two classes,

    import org.eclipse.jdt.internal.corext.callhierarchy.CallHierarchy;

    import org.eclipse.jdt.internal.corext.callhierarchy.MethodWrapper;

And then Create a method to get callers, and that takes the selected method as an input.(please note it will be your API type method) you should call this method from your program for find which methods call what..

If it’s a pure Java project with no other framework, one way to do this would be to use AspectJ to intercept every method, and put an entry in Thread local map for method name to counter + 1. If main is 0, foo2 would be 1, bar and bar2 would be 2, and so on.
See this section of AspectJ docs.

• All you need is to use ajc compiler instead of javac. It makes you able to use AspectJ. Using aspects you can define Pointcut and log what you need.
• Another option I think, could be analyze a stacktrase after all calls.

You can use a Plugin like Code Iris from IntelliJ
