Question

我开发了一个portlet应用程序，它在liferay-plugin-package.properties中启用了安全管理器：

security-manager-enabled=true

当应用程序启动时，我们在liferay 6.2 EE和6.2.1 CE日志（Tomcat 7包）中获得下面的堆栈跟踪。它只发生一次并且它不会破坏任何东西，尽管这个消息portlet工作得很好。如果我们在portlet的liferay-plugin-package.properties中禁用安全管理器，则不会发生此异常。这个类＆＃34; javax.faces.webapp.FacesServlet＆＃34;不在portlet的.WAR中，并且它没有在代码中使用（至少它不是直接使用，可能是依赖项）。 portlet包含这些门户依赖项，不确定它是否相关：

portal-dependency-jars=jstl-api.jar,jstl-impl.jar

请其他人遇到此问题吗？有什么想法解决它吗？

看来Maven已经在web.xml中自动生成了这些条目，可能是由于我这边的处理错误：Javax faces只包含在pom.xml中作为测试依赖项，可能是我们做过一次范围错误或其他什么那样的。

删除这些线条后，一切都很完美。谢谢！
