public abstract javax.servlet.jsp.PageContext extends (public abstract) javax.servlet.jsp.JspContext extends Object

javax.servlet.jsp.JspFactory _jspxFactory = javax.servlet.jsp.JspFactory.getDefaultFactory()

 

pageContext = _jspxFactory.getPageContext(Servlet, ServletRequest, ServletResponse, String, boolean, int, boolean)
