Description: Stop treating your Web Application Server as a black box.
Most Java developers press Run in their IDE and never think about what happens underneath. But the moment you need to configure a server from scratch, diagnose a production outage, or tune performance, that knowledge gap becomes a crisis. WAS for Developers is a hands-on guide built from real-world experience - not theory. It covers the two servers you are most likely to encounter on the job: Apache Tomcat and JBoss/WildFly. What you will learn:- Tomcat and JBoss/WildFly architecture from the inside out
- Server configuration - connection pools, JNDI, data sources, and virtual hosts
- Troubleshooting techniques for real production problems
- Performance tuning - thread pools, JVM options, and garbage collection
- Deployment strategies, logging, and security hardening
- Migrating applications from Tomcat to JBoss
- Real-world incident response scenarios and postmortems
