Javadoc is not enough: java2dot

I just wrote a tiny tool used to draw a graph for a java hierarchy. The input of the program is a set of jar files and the name of the classes to be displayed.

The source code is available here:

http://code.google.com/p/lindenb/source/browse/trunk/proj/tinytools/src/org/lindenb/tinytools/Java2Dot.java

. The information about each class is obtained using the java.lang.reflect API and the classes are dynamically loaded using an URLClassLoader. The output is a DOT file which is then piped into graphiz dot

As an example, the command line below was used to create the hierarchy of the com.hp.hpl.jena.rdf.model.Model.
It was generated using the following command line:

java -jar ./java2dot.jar

 -jar <dir0:jar1:jar2:dir1:...> add a jar in the jar list. If directory, will add all the *ar files
 -r  add a pattern of classes to be ignored.
 -i ignore interfaces
 -m ignore classes iMplementing interfaces
 -d ignore declared-classes (classes with $ in the name)
 -o  output file
