Developing Modern Applications With Scala
Scala is a general-purpose programming language. It has full support for functional programming and a very strong static type system. Designed to be concise, many of Scala's design decisions were inspired by criticism of Java's shortcomings. Scala source code is intended to be compiled to Java bytecode, so that the resulting executable code runs on a Java virtual machine. Java libraries may be used directly in Scala code and vice versa (language interoperability). Like Java, Scala is object-oriented, and uses a curly-brace syntax reminiscent of the C programming language.

Spring Framework Cookbook
The Spring Framework is an open-source application framework and inversion of control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE platform. Although the framework does not impose any specific programming model, it has become popular in the Java community as an alternative to, replacement for, or even addition to the Enterprise JavaBeans (EJB) model. It helps development teams everywhere build simple, fast and flexible JVM-based systems and applications.
