The Java Story: A Film About All of Us

Thu, 09 Jul 2026 08:43:59 +0000

Every so often a story comes along that belongs to an entire community rather than any one company or person. The Java Story documentary by CultRepo is one of those. On July 17th at 7pm UTC, the official Java documentary premieres live on YouTube - if you’ve spent any significant part of your career working with Java (and I assume most Foojay readers have!), I really think you’d want to watch it!

Tomcat TLSv1.3 cipher configuration

Thu, 26 Feb 2026 18:02:34 +0000

A recent update to Apache Tomcat introduced a subtle but significant change to how TLS cipher suites are configured. If your Spring Boot application explicitly configures TLS ciphers, particularly TLSv1.3 ciphers, and runs on Tomcat 9.0.115+ (Spring Boot 2.x), 10.1.52+ (Spring Boot 3.x), or 11.0.18+ (Spring Boot 4.x), your cipher configuration may be silently ignored.

Prior to the change, Tomcat used a single ciphers attribute on the SSL connector to configure cipher suites for all TLS versions. Starting with the versions of Tomcat listed above (Tomcat commit ), this attribute was split:

How to Deploy a Vaadin Application as a WAR on Tomcat 11

Mon, 19 May 2025 07:40:43 +0000

In this post, I’ll show you step-by-step how I did it.

Step 1: Download Tomcat 11

First, download Tomcat 11 from the official Apache Tomcat website . After extracting it to a local folder, you have a clean Tomcat installation ready to use.

Why I moved my blog to RIFE2 after 23 years?

Tue, 05 Mar 2024 06:42:47 +0000

In April 2023, I decided to move my blog to RIFE2 , a full-stack framework. It was previously built using my own custom JSP tag library , which ran non-stop for 23 years. At one point in time, it was handling close to 5 connections per second, or around 12 million a month, on a single Apache/Tomcat instance.

Over the years, I tried many frameworks, and the features never made up for the bloat. I’ve also never been a big fan of the MVC approach, and I wanted it to be very lean. RIFE2 no-dependencies approach immediately appealed to me, but I wasn’t sure the features passed muster.
