Java Jboss Oracle JDBC连接失败

Jboss EAP 6.3，Oracle 11g Express。 我有一个独立的oracle数据源：

                <datasource jta="true" jndi-name="java:/OracleDS" pool-name="OracleDS">
                <connection-url>jdbc:oracle:thin:@localhost:1521:XE</connection-url>
                <driver>oracleDriver</driver>
                <security>
                    <user-name>Boris</user-name>
                    <password>password</password>
                </security>
            </datasource>
            <drivers>
                <driver name="oracleDriver" module="com.oracle">
                    <xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
                </driver>
            </drivers>

数据源显示在Jboss管理面板中。我运行了一个测试连接，但它的响应是：

Unexpected HTTP response: 500

Request
{
    "address" => [
        ("subsystem" => "datasources"),
        ("data-source" => "OracleDS")
    ],
    "operation" => "test-connection-in-pool"
}

Response

Internal Server Error
{
    "outcome" => "failed",
    "failure-description" => "JBAS010440: failed to invoke operation: JBAS010447: Connection is not valid",
    "rolled-back" => true
}

在jboss控制台中，我发现：

Caused by: java.sql.SQLException: ORA-00604: error occurred at recursive SQL lev
el 1
ORA-12705: Cannot access NLS data files or invalid environment specified

但我在互联网上找到的错误解决方案没有帮助

我做错了什么？

ORA-12705错误表明这可能是区域设置问题。您可以尝试使用转换为NLS时使用的语言环境启动JBoss。例如，尝试将其添加到JBoss启动配置中（

jbossas/bin/run.conf

中的

JAVA\u OPTS

变量）：

Caused by: java.sql.SQLException: ORA-00604: error occurred at recursive SQL lev
el 1
ORA-12705: Cannot access NLS data files or invalid environment specified
