  1. Groovy and CFML CFGroovy: Groovy for CFML Developers Barney Boisvert

  2. Who Am I? Barney Boisvert Sr. Web Application Developer Mentor Graphics Corp. 10 years of CFML development 2 years of Spring/Hibernate development I try not to read slides. I don't always succeed.

  3. Who Are You? CFML developer Sense there's more out there Curious about other languages Curious about Java Platform technologies

  4. What We're Talking About Groovy, CFML, and Java Language selection Language integration Why it matters How it can help Billions of tiny magnets spinning around and around

  5. Java JVM based Java syntax Static typing Compiled Ceremonious Concise Huge ecosystem Widely adopted Stable

  6. CFML JVM based CFML syntax Dynamic typing “Compiled” Essential Verbose Small ecosystem Increasing adoption Cumbersome access to Java

  7. Groovy JVM based Extended Java sytax Dynamic typing Interpreted or compiled Essential Concise Small ecosystem Increasing adoption Direct access to Java

  8. Data Structures

  9. Java Access

  10. Groovy Language Features Closures Optional typing Literals (that actually work) Meta programming Inline DSLs Lots of “grease” http://groovy.codehaus.org/Documentation

  11. CFGroovy (1) Created in 2007 Initially a scriptlet focus Morphed into Hibernate focus Largely superseded by CF9's ORM Abandon-ware?

  12. Hibernate Demo Config Entity Saving Recall Implicit relationship traversal

  13. CFGroovy 2 Created at cf.objective() 2009 One CFM file (an 88 line custom tag) Scriptlet-only Shared output stream Pluggable languages

  14. Demo

  15. The Future Hibernate devalued by CF9 Return to scriptlet focus (CFGroovy 2) Scriptlet classpath Better CFML integration, where possible

  16. Groovy Gotchas zero- vs one-based indexing Map key case sensitivity Type ambiguity PermGen (CFGroovy only – not CFGroovy2)

  17. What's the Point? Use more/better tools Increase your skillset Bridge to Java/JRE piecemeal

  18. The Punchline!

  19. Soapbox* If you're not using version control, start. Before you write another line of code. If you don't use a Front Controller framework, start. (I like FB3Lite, but then I wrote it) Learn about your tools. They're all far more powerful than you believe. * I'm going to read this one verbatim. Sorry.
