先把问题踢出来:

我们重点来理解这句:javax.naming.NameNotFoundException: While trying to look up jdbc in /app.; remaining name 'jdbc'

意思是说，没有找到名称，在寻找jdbc的时候:

但是我在项目中没有使用look up来查找配置完的jdbc数据库，使用的项目EjbDemo已经删除，这里的jdbc是什么意思呢？

接下来，我们再往下看：

at weblogic.jndi.internal.BasicNamingNode.newNameNotFoundException(BasicNamingNode.java:1139)

这里的报错，显然不是我们开发端的问题。

我们把weblogical控制面板打开:如下图:

选择Deployments，进入下面:

发现删除的项目这里仍然存在，EjbDemo还在没有删除。

这里我们把EjbDemo删除即可或者停止，问题解决。
