Question

I need to understand a quite large Java project. I browse through it with eclipse and use the call hierarchy and all, but that doesnt get me quite the idea on what is happening when the project runs (it’s a webservice).

Is there a possibility to print out every method call with parameters to console?
Basically something that puts

System.out.println("methodName, params: " + param1.toString());

in every method for me.
Some kind of framework that provides that for example?

You should try to use Aspect-oriented programming (AOP).

Here is an example that does more or less what you want: How to use AOP with AspectJ for logging?
