我有一个java课

public void doView(
        RenderRequest renderRequest, RenderResponse renderResponse)
        throws IOException, PortletException {

//I need to pass the string variable over to my jsp
ThemeDisplay themeDisplay = (ThemeDisplay) renderRequest.getAttribute(WebKeys.THEME_DISPLAY);
String sLang_Id = themeDisplay.getLanguageId();

include("/html/mypackage/view.jsp", renderRequest, renderResponse);

}

我将如何阅读sLang_Id我的jsp

 <c:out value="${sLang_Id}" /> ???
