tomcat7.x中的java.util.concurrent.ExecutionException

我有点tomcat代码，通过在tomcat5.x的server.xml中添加以下行，它工作正常。tomcat7.x中的java.util.concurrent.ExecutionException

<Host name="nsncatbranch" debug="0" appBase="D:/svn/branch/rncom/modules/web/clients/web/web/operationsmanager" 
       unpackWARs="false" autoDeploy="false"> 

       <Logger className="org.apache.catalina.logger.FileLogger" 
        prefix="om_log." suffix=".log" 
        timestamp="true"/> 

     <Context path="" docBase="D:/svn/branch/rncom/modules/web/clients/web/web/operationsmanager" debug="0" 
       reloadable="false" crossContext="false" /> 
    </Host>

但是在tomcat7.x中它给了我下面的错误。

我没有得到上面的错误，因为我在web.xml中评论过调用者。我正面临下面描述的新错误。

你可以发布与该上下文相关联的web.xml吗？这似乎是问题。 – Patrick 2012-02-03 14:20:37

我认为你是对的我刚刚在web.xml中发布了servlet servlet行，并且抛弃了这个错误。现在我面临另一个错误，请验证我编辑的问题。 – chetan 2012-02-06 06:05:27

应用程序是否按预期工作？它看起来像错误是无害的，至少根据这个错误https://issues.apache.org/bugzilla/show_bug.cgi?id=52511 – Patrick 2012-02-06 13:48:25

我有同样的问题，帕特里克是正确的问题是在web.xml文件。我删除了下面的标签：

<servlet-mapping> 
    <servlet-name>invoker</servlet-name> 
    <url-pattern>/servlet/*</url-pattern> 
</servlet-mapping>

它工作正常。所以我的建议是再次检查web.xml文件并确保其中的所有内容都正常。
