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:

Null userid is not supported. ERRORCODE=-4461, SQLSTATE=42815JNDI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:
was的异常除了输出到logs\server1下面,还会输出到logs\ffdc下面。
