Presentations
Introduction to REST: What can we learn from it?
REST is a description of how the Web works, what use is that to developers just trying to build or integrate applications?
This presentation introduces REST, explains the key differences/constraints, and then highlights how these concepts can improve key parts of application and service development:
- scalability, integration, evolvability
Glassbox: Open Source Java Monitoring and Troubleshooting
In this session you will learn about the Glassbox open source troubleshooting and monitoring tool. Glassbox enable detection of common application problems such as database failures, slow operations, thread contention, and excessive distributed calls. Glassbox enables low overhead monitoring and troubleshooting without needing to “bake in” instrumentation up front.
Adding Behavior to Java Annotations
Java's Annotations provide a way to add data to program elements. Annotations are used to configure containers, describe persistence configuration, set security roles, and are defined by nearly every recent JSR standard. This presentation explains the processing options available for consuming Annotations and demonstrates the techniques with live code demonstrations.
