我想创建一个名为VisitCounter的JSR286 Portlet,安装在WebSpherePortal8.0上。VisitCounter统计联机用户数

public void doView(RenderRequest request, RenderResponse response) throws PortletException, IOException {
        // Set the MIME type for the render response
        response.setContentType(request.getResponseContentType());

        // Check if portlet session exists
        VisitCounterPortletSessionBean sessionBean = getSessionBean(request);
        if( sessionBean==null ) {
            //response.getWriter().println("<b>NO PORTLET SESSION YET</b>");
            return;
        }
        ........
}
public void doView(RenderRequest请求、RenderResponse响应)抛出PortletException、IOException{
//设置呈现响应的MIME类型
response.setContentType(request.getResponseContentType());
//检查portlet会话是否存在
VisitCounterPortletSessionBean sessionBean=getSessionBean(请求);
if(sessionBean==null){
//response.getWriter().println(“还没有PORTLET会话”);
回来
}
........
}
怎么做这个? 谢谢

public void doView(RenderRequest请求、RenderResponse响应)抛出PortletException、IOException{ //设置呈现响应的MIME类型 response.setContentType(request.getResponseContentType())

//检查portlet会话是否存在
VisitCounterPortletSessionBean sessionBean=getSessionBean(请求);
if(sessionBean==null){
//response.getWriter().println(“还没有PORTLET会话”);
回来
}
........
}

正在使用应用程序范围

    // Check if portlet session exists
    VisitCounterPortletSessionBean sessionBean = getSessionBean(request);
    if( sessionBean==null ) {
        //response.getWriter().println("<b>NO PORTLET SESSION YET</b>");
        return;
    }
