本文讲述在本地eclipse启动配置了jndi数据库配置文件的JBoss5.1.0GA时，因DS.datasource.book.com重复配置报错。解决方法包括删除jboss数据源配置文件、清空tmp和work文件夹，还可参考InstanceAlreadyExistsException的解决方案博客。

JBoss5.1.0GA配置了 jndi数据库配置文件oracle-ds.xml放到jboss目录 /C:/Java/JBoss/jboss-5.1.0.GA/server/default/deploy下面，在本地eclipse启动时报错，内容如下：

我报错的原因是因为 DS.datasource.book.com重复配置了，我把放到jboss中的数据库配置文件 oracle-ds.xml删掉了，然后就没有报错了，应该是数据源在其他地方已经注册过了，因为我看日志是正常注册了。

解决方法总结如下：

1.首先可以尝试删除放进jboss数据源配置文件，再次启动试试，防止重复配置数据源。

2.有时候是由于缓存引起的，清空 C:\Java\JBoss\jboss-5.1.0.GA\server\default 下面的 tmp和 work两个文件夹可以解决

3.有时也会导致 InstanceAlreadyExistsException报错，解决方法参考如下：InstanceAlreadyExistsException的解决方案_night field的博客-优快云博客_instancealreadyexistsexception

希望对你有帮助！
