我有一个错误已经让我发疯了。
这是与Tomcat的Liferay 6.1，我们正在讨论预生产环境。部署了一个portlet，但在部署阶段失败了。这是错误：
发生此错误后，我看到一条消息，指出portlet已取消部署。
我们尝试部署另一个之前正在运行的.war但错误仍在继续。此错误仅出现在preproducction environtmet中，因为在集成和生产环境中它正确工作。
我尝试过下一步： - 停止服务器 - 删除临时文件夹 - 删除工作 - 从webbapp中删除portlet - 启动服务器 - 检查文件权限 - 使用正确工作的其他struts portlet检查依赖项/ libs。
一无所获，只要部署了portlet（以前的版本），就会出现同样的错误。
portlet使用struts，我也尝试将库放在portlet中。但它仍然是一样的。
有什么想法吗？
这是错误：
