java.lang.Objectorg.apache.jasper.compiler.JspRuntimeContext
public final class JspRuntimeContext
Class for tracking JSP compile time file dependencies when the &060;%@include file="..."%&062; directive is used. A background thread periodically checks the files a JSP page is dependent upon. If a dpendent file changes the JSP page which included it is recompiled. Only used if a web application context is a directory.
