我已经下载了kie工作台并解压缩了kie-drools-wb-distribution-wars-6.2.0.Final- tomcat7.war。我以前从未使用过tomcat，但是我想使用工作台，但似乎没有选择让工作台简单地向上旋转。因此，我安装了tomcat8。完成此操作后，我访问了tomcat管理器并部署了war。（我必须增加可接受文件大小的内存限制）

我现在已/kie-drools-wb-distribution-wars-6.2.0.Final- tomcat7列为应用程序，但不会启动。当我尝试启动它时，我得到以下信息：

FAIL - Application at context path /kie-drools-wb-distribution-wars-6.2.0.Final-tomcat7 could not be started
FAIL - Encountered exception org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/kie-drools-wb-distribution-wars-6.2.0.Final-tomcat7]]

这是catalina日志文件：

我似乎在context.xml中存在某种解析错误。但是，由于这是直接从Drools下载的代码的未修改内容，因此我不知道它可能有什么问题。
