tomcat7服务器有错误filterstart，无法启动

Question

我正在尝试在 ubuntu 13.04 中的 tomcat7 下运行 solr 4.3.0。请查看下面的日志片段，这是我在尝试通过运行 catalina.sh 启动 tomcat 时得到的。如日志中所示，我收到错误 filterStart。我该如何解决？

我已经在/etc/tomcat7 的 server.xml 中将默认端口更改为 9999。我无法打开 localhost:9999 或 localhost:9999/solr。

您遇到的问题与 Solr 4.3 中日志记录机制的更改有关。来自Solr Logging页:

What changed

These versions do not include any logging jars in the WAR file. They must be provided separately. The Solr example for these versions includes jars (in the jetty lib/ext directory) that set up SLF4J with a binding to the Apache log4j library.

Why did it change?

The logging setup was changed for increased flexibility. With older versions, changing your logging mechanism required either building a special target from the source code or doing surgery on the WAR file. Now anyone can change to another logging mechanism or upgrade to newer component versions simply by changing jar files.

请参阅Using the example logging setup in containers other than Jetty了解配置 Solr Logging 以与 Tomcat 一起正常工作所需的步骤。当我升级到 Solr 4.3 时我遇到了同样的问题，这更正了它。
