Could not load [oracle/sql/converter_xcharset/lx20354.glb]如何处理？

centos下部署tomcat，启动运行一直打印下面的信息：

网上关于这个信息的解决方案大概有下面几种：

1. jar包冲突。我用的是oracle，只有一个ojdbc6.jar，也不可能冲突，其他jar包也好像没有冲突的地方
2. 数据库用户密码过期。已经核实状态是正常的，密码没有过期
3. 将oracle的jar包移动到tomcat下的lib目录。已复制了一份ojdbc6.jar包过去，但是问题依旧。

请教各位大神，还有什么其他可能的问题吗？

遇到相同问题，jar没重复，密码正常。解决不了，求解答。

有搞定么，求解

原因是因为在tomcat重启的时候，之前的tomcat的线程还没有完全关闭，最新启动tomcat就会报这个异常。
针对这种情况，在网上找了些原因
运行tomcat/bin/shutdown.sh,tomcat停止，但它的java进程还在，事不过状态为S(sleep)，不是运行时的R(Runnable)，如果不kill的话，这种进程越来越多

解决方法是重启Tomcat和Apache服务器，我把整个Linux服务器重启后就可以了正常使用，现做个记录，后面验证。同时也可以清除tomcat的临时目录（如：D:\tomcat-7.0.63\work\Catalina），避免文件冲突问题。

我是重新启动了下虚拟机，然后就好了
