Configuring the environment

The system requirements needed to run PRD are installing JDK and configuring the environment variables.

System requirements

To correctly execute PRD, the following are necessary:

• The Java Runtime Environment (JRE) 1.7 or higher installed
• The JAVA_HOME variable configured
• The PATH variable entry configured, pointing to [JAVA_HOME]/bin

While only JRE is necessary to execute PRD and the other applications that we will discuss in this book, we will also need the Java Development Kit (JDK) to develop one of the applications in the last chapters. For this reason, we will install JDK 1.7.

Note

JDK also includes the Java Virtual Machine (JVM), a series of tools that lets us develop Java applications, including a compiler, a debugger, the API source code, the JRE, and so on.
