Apache Roller

Apache Roller is the Java community's response to the influx of PHP-based blogging tools that started with WordPress.

Roller can run on Java EE servers like Tomcat, GlassFish, and JBoss, and works with relational databases like PostgreSQL, Derby, and MySQL.

The blogging engine is easy to install, comes with lots of in-depth documentation, and allows administrators to manage multiple blogs at the same time from the same installation, sharing users with each other and most of the core features.

Roller is quite a powerful solution and even if it can be used for local one-man blogs, it's best used when deployed in larger projects with multiple authors working on the same or with multiple, different blogs.
