tomcat /conf/server.xml file uses something like this: 

<JDBCRealm
            debug="99" 
			driverName="org.gjt.mm.mysql.Driver"
			connectionURL="jdbc:mysql://192.123.117.38/db1" 
			connectionName="user"
	        connectionPassword="pass"
		    userTable="TOMCAT_USERS" 
            userNameCol="user_name" 
            userCredCol="user_pass" 
			userRoleTable="TOMCAT_USER_ROLES" 
            roleNameCol="role_name" />
And then in the webapps/app/WEB-INF/web.xml you can use something like this to enable form based authentication: 
<security-constraint>
      <web-resource-collection>
         <web-resource-name>Protected Area</web-resource-name>
          <url-pattern>/secure/*</url-pattern>
          <http-method>GET</http-method>
          <http-method>POST</http-method>
   	      <http-method>PUT</http-method>
         </web-resource-collection>
      <auth-constraint>
         <role-name>webapp1</role-name>
      </auth-constraint>
    </security-constraint>
    <login-config>
      <auth-method>FORM</auth-method>
      <realm-name>Authentication Area</realm-name>
      <form-login-config>
        <form-login-page>/login/login.jsp</form-login-page>
        <form-error-page>/login/error.jsp</form-error-page>
      </form-login-config>
    </login-config>
And then use the login page such as: 
<html><title>login</title>
<body bgcolor="#99CCFF" OnLoad="document.Form1.j_username.focus();">
<h1 align="center">Login 
  page </h1>
<form method="POST" action="j_security_check" name="Form1" >
  <div align="center"> 
    Username: 
    <input type="text" name="j_username">
    

    Password: 
    <input type="password" name="j_password">
    

    

    <input type="submit" value="login" name="j_security_check">
     
  </div>
</form>
</body>
</html>
This will then require authentication for any pages in the secure folder. (ssl can be enabled also in server.xml to stop encrypt the data)
i would suggest to look in the tomcat manual as this is only intended to point you in this direction. the manual will explain it in english.
