title: Weblogic 12.2.1.3.0 Developer - Unable to create data source using admin console
body: <p>I have been trying to create a DataSource on my development machine using Weblogic 12.2.1.3.0 developer install using the admin console and I am getting an exception that I have not encountered before. I have verified that all of the connection information is correct and I can connect to the Oracle Database (v12.1.2) using SQL Developer and an IDE connection but the Weblogic server is not cooperating.
  This is the exception that I am getting:</p>
  
  <p><a href="https://i.stack.imgur.com/GJWyN.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/GJWyN.png" alt="DS Creation Exception"></a></p>
  
  <p>I have also tried creating a DataSource when the EAR file is deployed using descriptors and the DS is created and deployed but the connection pool for the DS cannot be created and the only exception that I am seeing is this:</p>
  
  <blockquote>
    <p>Connection test failed with the following exception: weblogic.common.resourcepool.ResourceDeadException: 0:weblogic.common.ResourceException: Could not create pool connection for datasource 'StipDS'. The DBMS driver exception was: null</p>
  </blockquote>
  
  <p>Anyone have any ideas? 
  Oracle has not been much help at all so far.</p>
