[Lift] Re: Started integrating lift in a scala+spring project. Feedback?
Yes, but I am referring to the case when there is no Full(session).
I.e. how do I get the servlet context in the 2nd case at the place
where I am currently throwing a RTE.
def servletContext = {
S.servletSession match {
case Full(session) = session.getServletContext()
case _ = throw new RuntimeException(no session)
}
}

[Lift] Re: Started integrating lift in a scala+spring project. Feedback?
Your best bet is to go find some Java static thing that's going to give you the ServletContext Yes that could work, but is it an idea to make the liftServlet available as an object in Lift (when it has the right provider)? Then the servletContext can be obtained nicely via liftServlet.getServletContext() --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Started integrating lift in a scala+spring project. Feedback?
Thanks Marius, that was what I was looking for! So in 1.0.2 I can call: def servletContext = LiftRules.context And when I upgrade to 1.1. I will change that into your suggestion. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Started integrating lift in a scala+spring project. Feedback?
Hmm, I am still confused... Maybe better to get into a specific use case. Suppose i have the following: 1) a lift application just serving stuff via the Servlet interface 2) an object in the ServletContext (let's say spring's ApplicationContext) 3) a snippet that does not need a session but needs access to this object in the ServletContext (let's say just some static content but reusing spring's i18n support) How do I get access to this object in the ServletContext from such a snippet? Or are you telling me that this use case makes no sense in Lift? Rintcius --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Started integrating lift in a scala+spring project. Feedback?
No, I think you mean there is not a guaranteed **session** (it is S.servletSession that returns a Box) I agree that once I go through the servletSession I should not just open_! the Box. But that's not the point I am trying to make. I think there should be a way to get the ServletContext without going through the servletSession. In other words: It's quite possible that there is no session in a lift snippet, but there always is a ServletContext (I assume..). However, it's a different question whether there's currently a method available in lift that enables me to get the ServletContext from a snippet (I couldn't find it).

[Lift] Re: Started integrating lift in a scala+spring project. Feedback?
Ok hopefully better phrased: It's quite possible that there is no session, while there is a ServletContext. The context of the request is going to depend on how the current session is instantiated. I don't get that. Quote from http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/ServletContext.html : There is one context per web application per Java Virtual Machine. (A web application is a collection of servlets and content installed under a specific subset of the server's URL namespace such as /catalog and possibly installed via a .war file.) So why is it depending on how the current session is instantiated? Rintcius --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Started integrating lift in a scala+spring project. Feedback?
Hi, I have started integrating Lift in a Scala + Spring example project (see http://code.google.com/p/scala-spring). This first integration just has a single template and snippet for now but should give an idea how Lift can be integrated. Before I go further with this I would like some Lift experts to review the code I have written so far. Anybody? The changeset that adds lift integration is in http://code.google.com/p/scala-spring/source/detail?r=18 Thanks, Rintcius --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Started integrating lift in a scala+spring project. Feedback?
Hi Tim, This project is meant as an example for people (like me) that maintain existing Spring architectures and are interested in using Scala and Lift. What I want to do now is port the existing jsp's and spring controllers to lift, so that people can compare jsp and lift-webkit with each other (and probably favor lift :) ). Currently I have just looked at the easiest way to integrate Lift and Spring (that is using the LiftFilter and access Spring's ApplicationContext), but I am also interested in other ways to integrate them (at a later stage).

Ok thanks David. What is the recommended way to get the ServletContext from a lift snippet (in 1.0.2)?

[Lift] Re: Started integrating lift in a scala+spring project. Feedback?
Hmm, isn't there a direct way to get the ServletContext? I mean now that I think about it looks to me that it should be possible to obtain the ServletContext no matter if there's a session or not. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] Re: Lift and interoperability
Interesting discussion! I think I see a bit where Glenn is coming from. To me it's about *ease* of interoperability. For enterprise architectures the most important question is: to what extent is Lift helping me to build a **composable** software system. A composable software system will offer gradual change from one architecture to another and it will make this migration easy. So suppose I am having a Spring based architecture with Hibernate and struts and want to migrate this to Lift. I think it would be a good exercise to check how such an architecture can be gradually migrated to a lift based architecture. So what to do if I just want to replace struts or hibernate. Or what if I want to start with migrating my POJO's to POSO's. My guess is that this is all possible in Lift but I haven't seen anything in the code or docs that facilitates this. Maybe I have overlooked something but what I have seen so far is based on an all or nothing approach (also nothing wrong with that, e.g. Grails doesn't facilitate this either and this is a very productive framework as well).
