Passing variable to jsp

问题

I have a java class

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);

}

How would I read sLang_Id in my jsp

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

回答1:

Add the following before your call to the include method:

renderRequest.setAttribute("sLang_Id", sLang_Id);
