Portlet暂时不可用 [英] Portlet is temporarily unavailable

问题描述

按照Liferay在《操作手册》中的说明为portlet编写编辑模式.我已成功部署了Portlet.此portlet在编辑模式下包含一个文本框和一个按钮.如果我在文本框中键入一个名称并按下按钮，则该名称将在portlet的查看模式下显示.但是，当我进入编辑模式并在文本框中键入名称，然后按添加名称"按钮时，会显示"Portlet暂时不可用"消息.

Im following Liferay in Action book instructions to write edit mode for a portlet. I successfully deployed the portlet. This portlet contains a text box and a button in edit mode. If I type a name in the text box and press the button, this name will be shown in view mode of the portlet. But when I go to edit mode and type a name in the text box and press the Add Name button it shows me "Portlet is temporarily unavailable" message.

更新:

我检查了日志文件.它说"javax.portlet.PortletException:processAction方法未实现".但是我已经实现了.

I checked the log file. It says "javax.portlet.PortletException: processAction method not implemented". but I have implemented it.

  @Override
    public void processAction(ActionRequest actionRequest, ActionResponse actionResponse) throws IOException, PortletException {
        String addName = actionRequest.getParameter("addName");
        if (addName != null) {
            PortletPreferences prefs = actionRequest.getPreferences();
            prefs.setValue("name", actionRequest.getParameter("username"));
            prefs.store();
            actionResponse.setPortletMode(PortletMode.VIEW);
        }
    }

推荐答案

您可以在日志中找到错误(假设您也使用Tomcat)

You can find the error in the logs (Assuming your also using Tomcat)

• 服务器开启时:liferayfolder/tomcatfolder/logs/catalina.out
• 服务器关闭时:liferayfolder/logs/liferay- 2012-03-11 .log(日期可以更改)

• When server on : liferayfolder/tomcatfolder/logs/catalina.out
• When the server is off: liferayfolder/logs/liferay-2012-03-11.log (date can change)

如果您使用的是Linux或Mac OS，则可以拖尾日志文件以对其进行实时监控.

If you are on linux or mac OS you can tail the logfile to livemonitor it.

例如:tail -f path\to\tomcat\logs\catalina.out
