Question

我正在为一个solr应用程序运行Tomcat服务器。我重新启动服务器并在catalina.out中观察到以下错误。

Exception configuring digester to permit java encoding names in XML files. Only IANA encoding names will be supported.

此错误的含义是什么以及如何解决？我根本不知道Java，所以任何帮助都将不胜感激。这是CentOs上的Tomcat6。

编辑日志文件：

我的问题是发现catalina.sh脚本的Java安装并不好。不知道为什么我没有调查。

这是一个centos 6 tomcat6 RPM安装。解决方法是安装Oracle JDK并更改/etc/tomcat6/tomcat6.conf以使用新安装的Oracle JDK。

以下Tomcat错误的原因是什么：
