session - JSR 286 Portlet 统计在线用户数

Question

我想创建一个名为 VisitCounter 的 JSR 286 Portlet 以安装在 websphere Portal 8.0 上。VisitCounter 统计在线用户数。

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;
        }
        ........
}

这个怎么做？谢谢！

public void doView(RenderRequest request, RenderResponse response) throws PortletException, IOException { // 设置渲染响应的 MIME 类型 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;
    }
    ........

}
