myeclispe来连接oracle数据库 ORA-00604 ORA-12705

用myeclispe来连接oracle数据库时出现了如下错误：

ORA-00604: error occurred at recursive SQL level 1
ORA-12705: Cannot access NLS data files or invalid environment specified

到网上一搜都是关于oracle编码的问题，但是我用jdbc连接却没有问题，可以运行，于是想到是不是eclipse本身的问题，最终终于在网上找到此问题的答案，原来是eclipse的环境编码和oracle的有冲突

oracle在注册表中NLS_LANG值为SIMPLIFIED CHINESE_CHINA.ZHS16GBK

eclipse启动时的配置文件eclipse.ini的-Duser.language属性却为en

将en改为zh，问题解决
