In this chapter we discuss the latest available Java level and tell you about some considerations you may face. 8.5.1 What is Java? Java is a language whose specifications are maintained by SUN Microsystems. The most important task of SUN Microsystems is to guard the Java philosophy: Develop once, run everywhere Java is packaged as a set of tools, better known as the Software Development Kit, or SDK. The SDK consists of a number of things: First of all there is the runtime environment, known as the Java Virtual Machine (JVMTM). This is the layer between the Java runtime code and the z/OS runtime environment. Basically, the JVM is the computing engine that executes Java applications on the zSeries Chapter 8. Exploitation 323
