Instead, similar to what cppyy strives to do for Python, it exploits the syntactic and semantic similarities between Java and C++. Under the hood, it uses JNI, so it works with all implementations of Java SE, in addition to Android, Avian, and RoboVM (instructions). ...

Last released version of the SchemaSpy was in 2010, and I have a plan to change this. Process of installation is very simple because SchemaSpy is only one Java .jar application. You can learn more read the installation doc. When you environment will be ready, and you can start using SchemaSpy you can read more about the configuration. Browse some sample pages generated by SchemaSpy. Note that this was run against an extremely limited schema so it doesn't show the full power of the tool.
