I added this file META-INF folder then The error won't come back.

context.xml:

<?xml version="1.0" encoding="UTF-8"?>
<Context path="/myapp" docBase="myapp"
   crossContext="true" reloadable="true" debug="1">
          <Resource driverClassName="com.mysql.jdbc.Driver" 
          maxActive="100" maxIdle="30" maxWait="10000" 
          name="jdbc/test" 
          type="javax.sql.DataSource" 
          url="jdbc:mysql://localhost:3306/test" username="root" password="root" />
