[Lift] Re: Lift and interoperability
I appreciate all the comments on lift and interoperability. What I'm hearing is that if an integration can be done in a plain old Java EE application, it can be done in lift. I never doubted that. It's just that I was hoping for a little transparency when it comes to resource management. If I want to grab a resource outside the lift application context, do I write plain html, Java EE code, lift code, or a hybrid? I can use an action attribute on an html form to submit a request to any URL, but I can't do that in a lift form template. Lift has api's to construct and process JSON and ATOM formats and even has REST methods to process them, but only if you plan on talking to yourself. I think a lift implementation of something like Ryan Dewsbury's JSONRequest class, in Google Web Toolkit Applications, would help.

[Lift] Re: OSGi support for Lift
Hi Alex, Yes, I do get that and these are exactly the things I'm looking for in moving to OSGi. However, as applications grow I think it's eventually necessary to modularize and isolate them so that changing something in one app doesn't affect another one. Yes, you are right. But so far OSGi does not support the concept of an application. Let's say I have 2 apps and I'd like one of them to run on Lift 1.0 and the other one on Lift 1.1-SNAPSHOT, how do you see this working? In a typical J2EE webapp, these would be deployed as separate wars, each having a separate web context and isolated Lift core instances. Two separate WARs means two separate applications which is not possible in OSGi so far. We could try to tweak this, e.g. by using non-overlapping version ranges on package imports. But currently Lift needs (evil) DynamicImport-Package to properly resolve classes (e.g. Snippets) which breaks version-based resolving. And there would be other issues, too. This whole application and isolation stuff is currently investigated by the OSGi EEG (enterprise experts group): Hopefully we will soon see a solution!

It's possible to write something in 1.0, but it's a lot harder...
basically,
you have to write a Snippet and do a custom LocParam.
Most of us are on 1.1-SNAPSHOT and the sites I deploy are on

[Lift] Re: how to display all template with chooseTemplate
Pravin, There's nothing magic going on with chooseTemplate or any of the other Lift Snippet code. The snippets take in a NodeSeq (a bunch of XML) and return a NodeSeq (a bunch of XML). XML is represented as NodeSeq which is a Seq[Node]. Seq[_] is the generic Scala representation for a linear collection of stuff, so all Scala collection operations (map, flatMap, filter, etc.) and works with Scala's for comprehension. The answers to your various questions are roots in manipulating XML which is basically Scala's collection manipulation. So, please spend some time learning about this basic Scala feature. We'll be glad to help you through the concepts, but I'm not sure answering small variants on how do I transform X to Y is going to give you the help you need.

The original version does not appear to have this functionality and Sun's maven-antrun-extended-plugin (which is supposed to supply this functionality) has so little documentation (that i could find) that i couldn't get it to work after an hour our so. - This version requires that BNFC, as an executable, be available on the path. Is there a blessed way to handle this sort of dependency? - i've got a hare-brained scheme that will fix this -- a meta-compiler-compiler from BNFC's input format to ANTLR's. i could include such a transform as a part of the project or a dependency and test for the availability of BNFC and fall back to ANTLR if it's not available. If anybody wanted to give this round of updates a whirl, even give me a code review, i would be very grateful. Best wishes, --greg -- L.G.

[Lift] Re: Lift and interoperability
Glenn, i'm not sure i've understood your concern. Are you saying that - web requests - lift are easy, but - lift - other services (web or otherwise) are hard? The latter direction is remarkably easy. Lift rests on top of Scala, Scala seamlessly interops with Java. So, anything you can do in Java you can do in Scala and therefore in Lift. Again, i may have misunderstood, but if there's a class or jar in GWT that you like, you can pretty much just use it (modulo hassles associated with dragging in its dependencies). You might want to look at DPP's longtime lift example where he puts together a comet-based actor framework in which you can handle potentially long-latency requests to some remote service -- using whatever transport + message formatting packaging you want (for which there are tons and tons of Java implementations that you can use out of the box). If you want some higher-level function or interaction method, maybe you could restate your concern. i think i'm still not getting it.

What I'm hearing is that if an integration can be done in a plain old Java EE application, it can be done in lift. I never doubted that. It's just that I was hoping for a little transparency when it comes to resource management. What resources are you looking to manage. Your original post lacked specifics as does this one. What is it that you want to do that you cannot (1) do with Lift or (2) do with some other JVM library because Lift is getting in your way? If I want to grab a resource outside the lift application context, do I write plain html, Java EE code, lift code, or a hybrid? What kind of resource do you want to grab? A database? An HTTP exposed service? In general, Lift is about servicing (responding to) HTTP requests, not about making them. There's nothing in Lift that I know of that impairs your ability to use other libraries to access external services. But, Lift is primarily about servicing, not making, HTTP requests. I can use an action attribute on an html form to submit a request to any URL, but I can't do that in a lift form template. This is just wrong. First, there's no such thing as a Lift form template. Lift's templating mechanism is a generic system for re-writing XML documents. There's no limit on how that re-writing can happen. What kind of re-writing do you want to do? How do you want the XML to appear? What kind of substitution do you want to make from a generic template into what is rendered to the browser? Lift has api's to construct and process JSON and ATOM formats and even has REST methods to process them, but only if you plan on talking to yourself. What does this mean? What does talking to yourself mean? I think a lift implementation of something like Ryan Dewsbury's JSONRequest class, This is a JavaScript class that operates on the client side (in the browser). There's nothing that bars you from using this class in your Lift-based application. If you are suggesting a Scala-based JSON request generator so that you can make JSON requests on external services, there are plenty of Java-based classes that do this and there's been no demand to writing a wrapper for one of these in Scala and include it with Lift. Once again, Lift is primarily concerned with servicing HTTP requests, not making them. in Google Web Toolkit Applications, GWT is a client-side technology, not a server-side technology. You can use GWT-based clients as front ends to Lift-based applications. As Marius said, be specific about what you want and why (you've seen the kind of support you've been getting related to the menu items... find me another framework team that adds features with a day or two turn-around when the feature is concrete). Continuing to be non-specific or just plain wrong is not helping your case. David would help.

[Lift] Re: Lift and interoperability
Glenn, I read with interest your mail below - to clarify, you've not been hammered by anyone... The lift comunity is a welcoming one and at no point would any member of the commit team shout down someone else - that's just not the way we roll. You expressed a viewpoint, and 4 seperate members of the team replied asking for various things to properly answer your mostly vauge question / comments. You chose to not answer these questions in a sucinct way which is why I suspect you feel hammered because people are just becoming a little frustrated with this thread... As a general rule, were really pleased when people come to the comunity and say something like XYZ feature is whack, it should do ABC - Lift simply wouldn't be what it is today if that didn't happen. However, coming on list and saying something like lift is difficult to integrate and provide no clarity or justification is, well, somewhat difficult and not overly helpfull - you won't get the answers you seek and everyone else just gets more email landing in there inbox :-) If you have a genuine hurdle, post a message, with relevant details, and you'll get a prompt and informative reply from either a lift team member or one of the great folks from the comunity at large. My suggestion to you: spend some time *really* getting to know lift, then perhaps re-visit this thread at a later date if you still feel the need to.

[Lift] Re: Menu access control not working as expected
David,
I changed default html in your menu example a bit and the results were
similar to using LocGroup -
the menu item won't display.
here's the change:
div class=column span-6 colborder sidebar
hr class=space /
!-- lift:Menu.builder /--
lift:Menu.item name=Fake
liFake Out/li
/lift:Menu.item
div
lift:snippet type=msgs/
hr class=space /
/div
/div
It seems this only works if you stick to outputting the full menu in
your templates with lift:Menu.builder/.
Anything else and it's broken.
