 protected Writer getOut() 
{
        return OutputConverter.getWriter(pageContext.getOut());
}

Get the outputWriter. This method should be used in preference to pageContext.getOut(), as some charset conversions may need to happen in some servers.

 protected Page getPage() 
{
        Page p = (Page)pageContext.getAttribute(PAGE, PageContext.PAGE_SCOPE);
        if (p == null) {
            p = (Page)pageContext.getAttribute(PAGE, PageContext.REQUEST_SCOPE);
            if (p == null) {
                pageContext.removeAttribute(PAGE, PageContext.PAGE_SCOPE);
            }
            else {
                pageContext.setAttribute(PAGE, p, PageContext.PAGE_SCOPE);
            }
            pageContext.removeAttribute(PAGE, PageContext.REQUEST_SCOPE);
        }
        return p;
}
