我面临一个问题，我无法在 tomcat 上部署我的 grails 应用程序，我正在按照以下书面步骤操作：
grails prod warmv target/app.war /var/lib/tomcat6/webapps- 使用重启tomcat
sudo service stop
问题是我的服务器启动但它没有部署战争，因为当我 goto 时/myapp，我得到一个 404。
我得到的日志是：

Resolved jbilling resources directory to:
Apr 11, 2012 4:25:30 PM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
Apr 11, 2012 4:25:30 PM org.apache.catalina.core.StandardContext start
SEVERE: Context [/jbilling] startup failed due to previous errors
Apr 11, 2012 4:25:30 PM org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc
SEVERE: The web application [/jbilling] registered the JBDC driver [org.postgresql.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
Apr 11, 2012 4:25:30 PM org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
SEVERE: The web application [/jbilling] created a ThreadLocal with key of type [null] (value [org.codehaus.groovy.grails.commons.spring.ReloadAwareAutowireCapableBeanFactory$2@127ea69]) and a value of type [java.lang.Boolean] (value [false]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
log4j:ERROR LogMananger.repositorySelector was null likely due to error in class reloading, using NOPLoggerRepository.

Log4j XML Plugin - please put a log4j.groovy or log4j.xml under /grails-app/conf, or uninstall this plugin
`
我什至在文件夹路径 /usr/share/tomcat6/bin/grails-app/conf 下有一个 log4j.xml 文件。
我尝试使用谷歌搜索，但我无法理解给出的解决方案，有人可以帮忙吗？
