websphere获取数据库连接时报用户名密码错误，但PL/SQL可以正常登录，大家帮忙看下，谢谢！
在集成解决方案控制台中测试也正常通过，java代码如下：
Hashtable parms = new Hashtable();
parms.put(Context.INITIAL_CONTEXT_FACTORY,
com.ibm.websphere.naming.WsnInitialContextFactory.class.getName());
parms.put(Context.PROVIDER_URL, "iiop://localhost:900/");
Context ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup("userdb");
错误日志：
Exception in thread "P=907546:O=0:CT" java.sql.SQLException: ORA-01017: invalid username/password; logon denied
DSRA0010E: SQL 状态：72000，错误码：1,017。

[解决办法]
WebSphere 配置数据源时提供了 JCA 登录配置条目吗？在先配置一个 JAAS 条目，输入用户名和密码，在配置数据源时选择这个 JAAS 条目名称，当我们 lookup 它时容器就会自动用这个 JAAS 条目中的用户名和密码来连接数据库。
另外你这个程序是什么环境中跑? 怎么像是 main 命令? 如果是运行在服务器中的程序就明了些。
