Glass fish and JEE 6 keynote at the server side java symposium

Oracle’s first slide is a TEN LINE disclaimer from their legal department.  Which must be standard because nothing was forward looking.

JEE 6

  • Split  sub platforms so less large
  • JEE web profile
  • New: managed beans, bean validation, CDI (dependency injection)
  • ejb 3.1 lite lets you use ejb in a war file
  • Ear files are now for backward compatibility
  • Encouraged use of setting up everything in annotations instead of web.xmk [I think somethings belong eternalized]
  • Putting a web-fragment.xml file inside your meta-inf directory lets jars contribute content to the web.xml
  • Can promote a managed bean to a “real ejb” to take advantage of transactions
  • Showed response builders for web services. Nice concise way if setting status, content type, result, etc.
  • Ejb 3.1 supports singleton and start up beans. Can set scheduled tasks and asynchronous tasks in annotations as well.
  • Going to great lengths to avoid mentioning Spring,  Guice was cited as the comparison/example of dependency injection. Speaking of Spring, this is the first time I’ve seen this much JEE 6 code. It looks a lot like Spring.

Glassfish

  • Web profile ships with REST
  • Glassfish is wonderful because Oracle says so. Not taking further notes on this. Do people really use Glassfish in production?

  1. Re: GlassFish – yep, people sure do. It’s very stable and performant. It may not (yet?) have JBoss’s numbers, but it’s what gets talked about. GF doesn’t feel like a RI at all – it’s production-ready.
