I am running the Tomcat server for a solr application . I restarted the server and observed the following error in my catalina.out .

我的问题是 catalina.sh 脚本发现的 Java 安装不好.不知道为什么，因为我没有调查.

My problem was that the Java installation the catalina.sh script found was no good. Not sure why as I did not investigate.

这是一个 centos 6 tomcat6 RPM 安装.修复方法是安装 Oracle JDK 并将/etc/tomcat6/tomcat6.conf 更改为使用新安装的 Oracle JDK.

This is a centos 6 tomcat6 RPM install. The fix was to install a Oracle JDK and change /etc/tomcat6/tomcat6.conf to use the newly installed Oracle JDK.
