public class JavaApplication
extends RunnableApplication

Component responsible for configuring command line for java based CasProcessor. Each CasProcessor is configured via CPE descriptor either statically (xml file) or dynamically by means of APIs. In both cases, the java-based CasProcessor to be launched by the CPE must be properly setup for launching. Its environment must be setup, command line, and any jvm arguments.
