        Description copied from class: JspFactory

        obtains an instance of an implementation dependent javax.servlet.jsp.PageContext abstract class for the calling Servlet and currently pending request and response.

        This method is typically called early in the processing of the _jspService() method of a JSP implementation class in order to obtain a PageContext object for the request being processed.

        Invoking this method shall result in the PageContext.initialize() method being invoked. The PageContext returned is properly initialized.

        All PageContext objects obtained via this method shall be released by invoking releasePageContext().

        Specified by:
        getPageContext in class JspFactory
        servlet - the requesting servlet
        request - the current request pending on the servlet
        response - the current response pending on the servlet
        errorPageURL - the URL of the error page for the requesting JSP, or null
        needsSession - true if the JSP participates in a session
        bufferSize - size of buffer in bytes, JspWriter.NO_BUFFER if no buffer, JspWriter.DEFAULT_BUFFER if implementation default.
        autoflush - should the buffer autoflush to the output stream on buffer overflow, or throw an IOException?
