  <p>I create a connection springstudent: with user spring student. Besides create a database with table on my workbench.</p>
  
  <p>I would like to connect my eclipse project on my database. So I write the code and add a library. </p>
  
  <p>My steps: </p>
  
  <ol>
  <li><p>Download apache tomcat</p>
  
  <p>Create web-dynamic project. Create a servlet  Add library
  my-sql-8.0.12</p>
  
  <p>Java compiler, Java built path, Project Facest have the same version</p>
  
  <p>I try to run doing both of the above settings:  Server Right Click
  priorities : workspace metadata  Server Right Click priorities :
  local</p>
  
  <p>Delete and add the server(Window->Show Servers...)  Check project
  facets->runtime apache clicked Clean project Clean server </p>
  
  <p>Delete and import project again.</p>
  
  <p>console:</p></li>
