我将Tomcat 7用作vaadin项目的Web服务器// Eclipse作为编辑器..它过去工作正常，但是昨天当我尝试运行服务器时出现此错误..我试图删除服务器并创建一个新服务器一个..但是没用

Answer 1

该痕迹最重要的部分似乎是

 The servlets named [com.example.teamonelibraryapp_.Teamonelibraryapp_UI$Servlet] and 
 [ui.AppMain$Servlet] are both mapped to the url-pattern [/*] which is not permitted
    at org.apache.catalina.deploy.WebXml.addServletMapping(WebXml.java:293)

因此，最有可能的是，将那些servlet映射到不同的url将解决您的问题。
