Apache Tomcat^®

The Apache Tomcat^® software is an open source implementation of the Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket technologies. The Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket specifications are developed under the Java Community Process.

The Apache Tomcat software is developed in an open and participatory environment and released under the Apache License version 2. The Apache Tomcat project is intended to be a collaboration of the best-of-breed developers from around the world. We invite you to participate in this open development project.

Apache Tomcat software powers numerous large-scale, mission-critical web applications across a diverse range of industries and organizations. Some of these users and their stories are listed on the PoweredBy wiki page.

Apache Tomcat, Tomcat, Apache, the Apache feather, and the Apache Tomcat project logo are trademarks of the Apache Software Foundation.

As part of the EU-FOSSA 2 project, there will be a Tomcat Hackathon in Brussels, Belgium on 4-5 May 2019.

The outline of the schedule is:

• general update on the status of the project
• hacking
• wrap-up

with the majority of the time spent hacking.

We are currently collating potential tasks on the wiki.

The EU-FOSSA 2 project is providing accommodation (on the basis of 2 people sharing - you can request a single room if you want to pay the difference) and might be able to help with transport costs.

Space is limited so we are asking anyone who would like to attend this hackathon and contribute to the development of Tomcat to register yourself.

Time is fairly tight so if you are interested please let us know ASAP.

We hope to see you in Brussels.
