Sincerity: Put your Favorite Stack on Java

The Sincerity project, an open source project supported by Three Crickets LLC, announces the beta version of Sincerity, Sincerity is a tool for deploying, installing, and bootstrapping software stacks on top of the JVM."
The goal of the project is to create an easy way to install web software stacks on the JVM platform. Sincerity works with frameworks that did not originally come from the Java world, but now also run on the JVM thanks to a Java implementation of the programming language (for example, Ruby on Rails and Django). Sincerity also supports the Big Data framework Hadoop, the servlet container Jetty, the Apache Solr search engine, the OSGi platform Apache Felix, the repository manager Sonatype Nexus, and the Lightweight Java Game Library. The software currently supports projects that are written in Javascript, Python, Ruby, PHP, Lua, Groovy, Clojure, and Scala.
