Criteria for Innovative Success

By John Heintz
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.
The presentation:
* introduces Annotations and how to create custom Annotations,
* surveys the techniques that can add implementation effects from Annotations (code generation, bytecode transformation, runtime reflection),
* demonstrates adding behavioral effect to an example with APT, Reflection, Javassist, and AspectJ,
* wraps up with best practices for using and defining Annotations.
No prior experience is necessary, and attendees will learn how to define and to provide behavior for custom Annotations in their own systems.
Tool support for Agile Databases: Introducing Liquibase
By John Heintz
This presentation introduces and demonstrates Liquibase: a new Java tool to support automating database refactoring and deployment.
Agile Database tools and techniques have been evolving to catch up with the existing support for source code. Many projects struggle to keep external databases (and DBAs) in sync with rapidly changing and tested source development.
Support for Agile Database development needs to include tools support for the following areas:
* Database Refactorings
* Schema Version Control
* IDE Support
* Scripted tools (Ant, Maven, command line)
Liquibase is an LGPL-licensed Java tool for tracking, managing, and applying database changes. Liquibase enables the database schema, reference data, and data change scripts to be managed as effectively as source code on Agile projects:
* the CI build doesn't break from forgotten SQL script runs
* developers don't have to coordinate check-ins/outs with each other
* embedded or external databases can be managed with the same scripts
* databases can be automatically upgrades, or SQL generated for review
This presentation introduces these topics and demonstrates Liquibase with an example application showing Spring Framework, Ant, and continuous build integrations.
Introduction to REST: What can we learn from it?
By John Heintz
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
Introduction to REST
Constraint-based Architecture
Hypermedia
Properties of REST
Constraints of REST
