Runtime Code Generation for Java and Beyond

Every now and then, it's really helpful to be able to generate a new Java class at runtime. Some problems just can't be solved any other way. It's one of those troublesome tasks: it's fairly tricky to do, and you only need to do it occasionally—but when you need it, you really need it (and usually you need it yesterday). So you have to start essentially from scratch, learning about how to do it on the fly, under pressure.

This talk is designed to help. You may not face this problem for a while, so there's no point focusing on the arcane details that you'll soon forget. Instead, I'll give you what you'll need to quickly come back up to speed when the time comes. You will see some real bytecode generation, but more importantly we'll discuss the types of problems where runtime code generation can save the day, the variety of tools and techniques that are available, and a step-by-step approach to getting the job done. Finally, for those who may be working with more dynamic languages, I'll show how powerful runtime code generation can be when it's easy. We'll start simply, but before we're done we'll be pretty deep into the bag of tricks. Come along, and be ready for the next time you need more than what's in your JAR file.
