Class JREDesc

  • public class JREDesc
extends java.lang.Object
    The java element (or the j2se element) (sub-element of resources) specifies what Java Runtime Environment (JRE) versions an application is supported on, as well as standard parameters to the Java Virtual Machine. Several JREs can be specified in the JNLP file, which indicates a prioritized list of the supported JREs, with the most preferred version first.
