【问题描述】：

我正在尝试让一些演示工作，但一直遇到问题。我正在使用 Tomcat 7 + MySql。当我尝试在 http://repository.portletfaces.org/content/repositories/liferay-releases/com/liferay/faces/demos/jsf2-portlet/3.1.0-rc2/jsf2-portlet-3.1.0-rc2.war 找到的 jsf2 portlet 演示时，我的日志（为 log4j 配置）显示它已注册但立即取消注册。我不知道为什么，也没有在日志中看到任何原因。我将不胜感激。

有问题的日志条目是：“04:17:55,430 INFO [PortletHotDeployListener:470] 正在取消注册 jsf2-portlet 的 portlet”。

以下是通向上述内容的内容。

【解决方案1】：

您描述的行为通常意味着仍然发生异常，它只是 Liferay 没有正确记录。大多数情况下对我有用的方法是将 logging.properties 文件添加到我的 portlet 的 WEB-INF/classes 目录中，并为其提供以下内容：

handlers = org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
org.apache.juli.FileHandler.level = FINE
org.apache.juli.FileHandler.directory = ${catalina.base}/logs
org.apache.juli.FileHandler.prefix = catalina.

java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

在部署这个新的 WAR 之后，您应该会看到额外的日志记录，可以帮助您找到部署失败的原因。
