将变量传递给jsp

Question

我有一个java类

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);

}

我怎么读sLang_Id我的jsp

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

Answer 1

在调用include方法之前添加以下内容:

renderRequest.setAttribute("sLang_Id", sLang_Id);

API可在http://portals.apache.org/pluto/portlet-2.0-apidocs/index.html?javax/portlet/RenderRequest.html上参考.
