Very cool. I'm sure there are some things that we can incorporate here.

 Hi guys.

 I have thrown up the little JEE container framework that I wrote for
 my company last year. I have already written some about what we did on
 my blog.

 In short it has support for:

 
 - JPA -
 JPA Template, Genenic Repository etc.

 
 - JTA -
 EJB-style TX semantics: REQUIRED, REQUIRES_NEW, MANDATORY, NEVER,
 SUPPORTS. It hooks into Hibernate/JPA. Can make use of the AOP
 framework to allow decorating your methods with:

 import javax.ejb.{TransactionAttribute, TransactionAttributeType}

 trait Foo {
  @TransactionAttribute(TransactionAttributeType.REQUIRED)
  def foo(msg: String)
 }

 
 - AOP -
  A simple generic Interceptor/AOP framework. Uses either annotations
 or the AspectJ pointcut parser.
 See my blog for a detailed post:

 http://jonasboner.com/2008/12/09/real-world-scala-managing-cross-cutting-concerns-using-mixin-composition-and-aop.html
 (last half)

 
 - Caching -
 Annotate your methods with '@Cacheable' to have the cached in a
 performant way.

 
 - DI -
 We used the Cake Pattern, but used Guice at one point, should be easy
 to add that again if requested.
 See this article for details:

 http://jonasboner.com/2008/10/06/real-world-scala-dependency-injection-di.html

 You can find all code here:
 http://github.com/jboner/skalman/tree/master

 Here is the JTA stuff:

 http://github.com/jboner/skalman/blob/610ad8918111c56284640f04ff7dcce7c33d3e5b/core/src/main/scala/JTA.scala

 Please come with feedback if there is anything that would fit Lift.
 Especially the JTA stuff since that have been discussed to be added.

 Thanks.

Cool. Thanks. I'd need some feedback here, since I don't have much
knowledge in what Lift needs and how it can be integrated.

[Lift] Re: JEE stuff (JTA, JPA, AOP etc.)

2009-04-05 Thread Derek Chen-Becker 
I think it would be nice to get the Transaction stuff easier to integrate.
Perhaps a Transactional marker trait that could be applied to snippet or
view classes:

trait Transactional {
  def transactionalMap : PartialFunction[String,Boolean] = {
case _ = true
  }
}

The transactionalMap def could be used to explicitly make particular snippet
methods transactional or not. Just a rough idea. The bulk of the work in
this case would be in LiftSession, I believe.
