JDBC and MySQL: Getting rid of the dreaded message – WARN: Establishing SSL connection without server’s identity verification is not recommended

When connecting to a MySQL database, you may encounter this scary warning message.

Thu Feb 04 14:49:25 IST 2016 WARN: Establishing SSL connection without server’s identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn’t set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to ‘false’. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

Your app will continue to work fine … it is just the MySQL database yelling at you.

To get rid of the warning message. Append ?useSSL=false to the end of your database connection string.

For example,

Replace – jdbc:mysql://localhost:3306/demo

With – jdbc:mysql://localhost:3306/demo?useSSL=false

Note that I appended ?useSSL=false to the end.

That will get rid of the pesky message … whew!


JSF: Handling Dates in JSF Forms

In this article, I show you code examples on how to handle dates in JSF forms.

The project consists of three files:
– student_date_test_form.xhtml
– student_date_test_response.xhtml

The user enters the student data into the form: first name, last name and hire date. The input format for the hire date is day, month, year. As an example For 1 May 2016, you would enter: 1-5-2016.


Once the form is submitted, then the app will show the output.



Here’s the code. Enjoy!
