配置的db2的数据源通过控制台的测试连接能够连接成功，但是部署应用的时候就报错了：

英文的报错信息是这样的：

Null userid is not supported. ERRORCODE=-4461, SQLSTATE=42815

JNDI获取连接的代码：

Connection conn = null;String jndiName = "test";DataSource ds = null;Object ref = null;Context ctx = null;String s="0";String flag="d";String errorMsg="";try {try {ctx = new InitialContext();ref = ctx.lookup(jndiName);flag="f";} catch (Throwable localThrowable) {s="1";}try {if (ref == null)ref = ((Context) ctx.lookup("java:comp/env")).lookup(jndiName);} catch (Throwable localThrowable1) {s="2";}if (ref == null) {ref = ((Context) ctx.lookup("java:comp/env")).lookup("java:comp/env/" + jndiName);}ds = (DataSource) ref;} catch (NamingException e) {// TODO Auto-generated catch blocke.printStackTrace();s="3";} finally {if (ctx != null)try {ctx.close();} catch (NamingException e) {// TODO Auto-generated catch blocke.printStackTrace();}}if (ds != null) {try {//conn = ds.getConnection("db2admin", "qwe123!");conn = ds.getConnection();System.out.println(conn);} catch (SQLException e) {e.printStackTrace();flag="gg";errorMsg=e.getMessage();}}

如果采用下面的方式赋予用户名和密码获取连接就没有问题：

conn = ds.getConnection("db2admin", "qwe123!");

分析一下，应该是数据源配置的有问题，就是数据库用户名和密码没有传到JNDI的数据源当中,但是为啥控制台的测试连接能够成功，不解？？

用户名和密码相关的：JAAS － J2C 认证数据配置的没有问题后来发现：

资源-》JDBC-》数据源点开配置的数据源有下面的配置：

只要在这块组件管理的认证别名中选择配置的JAAS － J2C 认证数据就行，如下：

再次部署就成功了。

was的异常除了输出到logs\server1下面，还会输出到logs\ffdc下面。
