I have a Java object with some unknown structure. Now I want to output this structure (properties and their values) to log file. And of course I’m interested to do this in recursive mode. Are there any libraries that can help me?

XStream is extremely good at printing object graphs, even handling cycles without any extra configuration or extra code in your classes (i.e. no messing with toString()’s). Just add the library and you can do this to anything and get nice, useful output:
That will give you XML output. If you prefer JSON, you can get it with a tiny bit more work as detailed in the XStream JSON tutorial.
