      public class JspContextWrapper
      extends javax.servlet.jsp.PageContext
      implements javax.servlet.jsp.el.VariableResolver

  Implementation of a JSP Context Wrapper. The JSP Context Wrapper is a JspContext created and maintained by a tag handler implementation. It wraps the Invoking JSP Context, that is, the JspContext instance passed to the tag handler by the invoking page via setJspContext().
