I need to represent graphically a directed graph, with possibility of defining events when clicking the nodes.
But the library needs to be free, because it's for a professional purpose and I won't get lucky on getting a paid one.
See Java graph library

I wonder, is there some powerful handwriting recognition libraries which can work not only with separate characters, but with whole words and sentences?
Try using Tesseract-OCR , it seems to be a good OCR Engine

What is the best Open Source Web Crawler Tool, written in Java.
Try crawler4j. You just need to implement a simple interface which controls which URLs to visit and what to do with each crawled page.
in java I think it boils down to Nutch vs Heritrix. You should specify what your needs are to get a better answer.

I am looking for Java libraries to produce data in KML format.
It appears there are at least three Java libraries for Keyhole Markup Language (KML):
JAK
gekmlib
kmlframework
As far as the best, that would depend on your needs. JAK appears to be the best supported at the present time.

I create a graph based visual applicaion using a Netbens Visual Library.
Can somebody post a code sample that enables a selection of nodes with mouse clicks (and Ctrl key fo multiple selection) ?
Thanks in advance.
http://graph.netbeans.org/examples.html contains many well written examples. Don't miss test.action.SelectLockedActionTest!
same link, but test.object.MultiMoveActionTest is a more relevant example.
