websphere8.5部署应用：不支持 userid 为空。 ERRORCODE=-4461, SQLSTATE=42815 DSRA0010E: SQL 状态：42815，错误码：-4,461

       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 block
	e.printStackTrace();
	s="3";
} finally {
	if (ctx != null)
		try {
			ctx.close();
		} catch (NamingException e) {
			// TODO Auto-generated catch block
			e.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。
