[Lift] Re: Length too long for generated XML

[marius d.]

Scala's XML support is based in immutable objects meaning that you can
not change them but rather generate new structures.

Lift is very flexible and allows you to apply your own xhtml
transformation right before the response is sent down to client.

LiftRules.responseTransformers.append {

  case XhtmlResponse(node, docType, headers, cookies, code,
renderInIEMode) => // do whatever you want with node and return a new
XhtmlResponse
  case resp => resp
}

Br's,
Marius

[Lift] Re: Why do geeks like to use the language of ancient Ashdod instead of koine Greek or simple English?

[Timothy Perrett]

Johnie,

If you have a problem with lift, or are finding something lift-related
difficult to understand, by all means raise it on this list and there
is a good chance if its a problem with lift we'll do something about
it, pronto. However, if you have a problem with the way I construct
sentences or my selection of words, there is next to no chance of my
changing my accent or colloquialisms - let alone someone i've never
met and now have very little desire to ever meet changing them on a
public mailing list!

Im not sure about you, but I certainly have better things to be doing
with my time. This conversation is going nowhere - please take it
elsewhere.

Tim

[Derek Chen-Becker]

"I can easily make a second copy of the master file and change the format
there to match the Sony Reader specifications, but there are many formatted
items like tables, figures and forced line breaks that are based on an 8.5 x
11 inch (US Letter) page. Changing the page size without also fixing those
manual formatting items would probably make those items run off of the right
edge of the page, or may make them disappear entirely from the output."

Fixed.

[Lift] Re: Why do geeks like to use the language of ancient Ashdod instead of koine Greek or simple English?

[Alex Boisvert]

Hi Johnie,

Like many other words, "funky" has loose and varying meanings.  I'm not a
native English speaker myself so I asked my wife what "funky" means and she
said "interesting", "strange" and "unusual".

The American Heritage
dictionarysays: "When
asked which words in the English language are the most difficult
to define precisely, a lexicographer would surely mention *funky."*

Yes, we could all go and use simple English but that would be a shame
because language can be so colorful.

[Lift] Re: Using ExtJS

[David Pollak]

You can mix ExtJS into the project without any work at all.  If you want to
use ExtJS exclusively, then you'll need to do the adapter thing so Lift
knows how to communicate with the server (Ajax, Comet, etc.)

Yes, Funky makes no sense if it means "very good" to one person and
"very bad" to another person.  So why not just say very good or very
bad if that is what you mean?  I see no reason for Geeks to make
things more confusing by using local slang instead of simple
language.

I have notices as I lived in several countries where various
languages
were spoken that the two groups of people who misuse language most
are Geeks and lowest class such as druggies and criminals.  The
people
of ancient Ashdod were condemned for making Babel even worse.  Only
twice since then has the world enjoyed a near lingua franka.  I would
hate to see simple English die like koine Greek because certain
classes
want to communicate in ways that are confusing.

A group of linguists were eating together at the University of
Michigan
years ago.  I started a conversation by inviting everyone to proclaim
why their language should be adopted by the rest of us.  One person
proposed that Arabic should be preferred because it was one of the
most difficult.  My vote went for koine Greek because the affixes
make
it so easy to understand.  In fact it is still so easy that most new
pharmacituals are a combination of Greek roots because the meaning
of new words can be ascertained the combination of simple roots.
So why would anybody who wants other people with other native
languages and cultures use words which mean very good in one
context and very bad in another context?  Do you want to play the
difficult game of writing a computer program which explains
context?  I believe I can write that program for a lot of koine Greek.
I do not believe you or anyone else can write it for the class of
modern English which includes funky.

[Lift] Re: Using ExtJS

[Charles F. Munat]

Wait. Is that right, guys? Does the LGC need JQuery or YUI?

If not, then you only need to use an adapter and one of those if you are 
going to use the built-in Lift Js helper methods. So I guess it's 
possible to use ExtJs 3.0 without any adapter if you're not going to use 
the helper methods.

Sorry if I'm just confusing the issue. I am using ExtJs on a Lift site 
with no problems (other than that ExtJs is a PITA).

@glenn - download this little tool... it will help you both with
executuing different HTTP requests, and perahps help you understand

http://code.google.com/p/rest-client/

I strongly recommend you read up on HTTP and REST resource orientated

[Lift] Re: Why do geeks like to use the language of ancient Ashdod instead of koine Greek or simple English?

[Timothy Perrett]

Johnie,

What on earth are you going on about? You qoute me there from a
convesation on-list with Heiko about OSGi... out of context it makes
no sense of course...

What is your point with this post? It appears to escape me. Im not
sure 900+ people wanted to read your comparison of one persons
grammatical style vs another; if you have issue with mine, or other
peoples use of the english language, or my intended interpretation of
correspondence, please bring it up with me off-list.

This is a public forum where-by people from all manner of countries,
cultures and so-forth communicate - im very confused why you cannot
take such english slang in-context of the conversation, like any other
normal person.

Regards

Tim

[Lift] Re: Using ExtJS

[Charles F. Munat]

You'll need to use an adapter for either JQuery or YUI because the Lift 
garbage collector depends on that.

There are no Lift JS functions specific to ExtJs, but as you'll be using 
either JQuery or YUI for the GC, you can use Lift's JQuery/YUI helpers 
for non-ExtJs stuff. For things specific to ExtJs, you'll have to build 
your own helpers, but you can probably just copy, paste, and modify the 
others to get what you want.

ExtJs probably can't be built into Lift because of licensing issues, so 
you'll have to do some work for yourself.

[Lift] Re: Lift for non UI, xml REST server embedded in existing application?

[glenn]

Tim,

If I have a PUT dispatch case like so:

case r @ Req("api" :: "company" :: Nil, "", PutRequest)=> () =>
addCompany(r)

and the handler is looking for something in r.xml  like this:

req.xml match {
   case Full({parameters @ _*}) => {
 for(parameter <- parameters){parameter match{
case {name} => company.name
(name.text)
case {line1} => company.line1(line1.text)
case {line2} => company.line1(line2.text)
case {city} => company.city(city.text)
case {state} => company.state(state.text)
case {postalCode} =>
company.postalCode(postalCode.text)
 case _ =>
}
 }

what would my PUT URL actually look like? The lift book shows

http://www.pocketchangeapp.com/api/expense - PUT - addEntry(request) +
XML Body as an example, but I don't really understand that in the
context of third-party
app sending the request.

[Lift] Re: Using ExtJS

[David Pollak]

Jesse,
It's pretty simple from a technical standpoint.   Just implement
the net.liftweb.http.js.JSArtifacts interface for ExtJS.  Then, set
LiftRules.jsArtifacts to an instance of your class and all will "just work".

Thanks,

David

[Lift] Why do geeks like to use the language of ancient Ashdod instead of koine Greek or simple English?

[johnnie]

A documentation author for Lift said,
   Hmmm. I can easily make a second copy of the master file and change
the
   format there, but there are a lot of tables and other things that
right now
   are set for 8.5x11. They would all come out looking pretty funky, I
think.
So I suppose funky just means "very bad."

But a Lift programmer said,
   Oh man, this is going to be nice - loving your work Heiko feels
   like this is the first brick in the road to something extremely
   funky.
So I suppose funky just means "very good."

But interested innocent people are just very confused.

[Lift] Error with tictac example

[Xavi Ramirez]

Hello,

There seems to be an error in the tictac on the following line:
registerCleanupFunc(() => is.foreach(who => LobbyServer ! RemoveLurker(who)))

I've changed the code to this:
override protected def onShutdown(session: CleanUpParam) {
  is.foreach(who => LobbyServer ! RemoveLurker(who))
}

I'm not sure if this is correct, but it seemed to get rid of the
error.  Just wanted to let you-all know.

Thanks,
Xavi

Or... it requires that you change:

case Req("api" :: "place" :: Nil, _, GetRequest) =>


to

case Req("api" :: "place" :: Nil, _, PutRequest) =>


Three whole letters to service a PUT instead of a GET.

Do you want everything to live in the same WAR file?  If you, set your
web.xml file to send requests to your REST apis to the LiftFilter.  If you
need something explicit, please let us know and I'll work up a specific
example.


>

So, once you've got your web container forwarding the API requests to your
Lift app, just write some of the api code (pattern matching on the incoming
requests) and use your existing persistence classes.

Is this enough for you or is it too abstract?  I'll be glad to work up an
example if it's too abstract.

Thanks,

David

[Lift] Using ExtJS

[Jesse Eichar]

Hi,

I was wondering how plausible using ExtJS since Lift adds some Ajax
libraries.  ExtJS requires adapters to work nicely with others.  I am
not sure if the adapters need to be ran with the specific version of
(say YUI or JQuery) the library that is shipped with Ext or if the
adapters are enough by then selves.

But really my question is:  Is it possible to use advanced ExtJS in
Lift?  And what would the recommended way be?

Thanks,
Jesse

I'm all for interoperability... I like baseball and apple pie, too.  If
there is a problem with Lift interoperating with another system or another
piece of J(2)EE infrastructure, be specific about it and we'll work on.

To date, Glenn has complained a lot and made very little sense and has not
been specific.  He's complained that you can't create a form to be submitted
to an external server that won't somehow magically execute functions defined
on your server.  He's complained that Lift doesn't have its own
implementation of some JavaScript functions which are available in existing
JavaScript libraries.  To date, Glenn has demonstrated little in terms of
understanding if code is executing on the server, in the browser or on some
other server.  This makes it very difficult to have a coherent
conversation... and every time we've asked him for specifics, he's ignored
us or give examples that are very far off the mark.

Okay... so there's a ton of documentation on the use of JPA within
Lift-based apps.  Derek has written a lot of this and does a lot of support
on this list of people using JPA within Lift and Scala.  Further, if you've
already got Java/JPA code, *IT JUST WORKS* inside Lift and Scala.  There's
nothing to document beyond "just use it."

I personally recommend starting with building your REST APIs with Lift.
 It's an easy way to get your hands dirty with Lift, you get to preserve
your existing models and it's very easy to do REST and XML/JSON within Lift
and Scala.

Lift is not primarily focused on persistence.  Lift is primarily focused on
the servicing of HTTP requests.  We will help people on this list with
JPA-related stuff, but it's not the primary focus of Lift as a web
framework.

That's because it's not a "Lift thing", it's a persistence thing.  Please
look at Exploring Lift, there are a ton of JPA-related examples.

I disagree with this.  Glenn was complaining that "Lift didn't do
everything" for him and that's how he seems to define interoperability.
 Lift in fact interoperates with all things in JVM-land.  If there's
something you want to do on the JVM and Lift is getting in your way, please
let us know.  We'll work on it.

Lift is simply a ServletFilter and can intercept as many or as few HTTP
requests as defined by your web.xml file.  If you simply want to use Lift to
service a single URL, you put that in your web.xml file and away you go.  If
you want Lift service all the URLs in your app, that's the define web.xml
file.  If you want to use Lift's mapper for RDBMS related stuff, cool, but
if you want to use JPA, existing home grown classes, whatever, you're
welcome to.  If you want to talk to PayPal, Lift has APIs for that... but
you can use your own.

At the end of the day, Lift can be as big or as small a part of your
application as you want.  If you have a specific requirement, please let us
know and we'll help you through it.

Thanks,

David

Hmm - im afraid your just plain wrong here... it needs nothing of the
sort. I have lift applications that are 100% back-end process, and
have no UI, or rather, the UI is an objective-c cocoa desktop
application. No magic included. Lift is extreamly good at building
REST services as it has a very flexible HTTP handling mechanism. I do
wonder though, if you already have a GET dispatch, what you cannot
figure out how to do PUT? (look at net.liftweb.http.PutRequest and how
its used in Req pattern match)

@barry: You can do what you want without any issues. Lift is
implemented as a filter so can co-habbit with other servlets etc. Lets
assume that you implement the lift element under /badger - configure
your web.xml correctly then only /badger/* requests get passed to
lift. Technically speaking there is no difference in serving XHTML and
XML... its all XML at the end of the day; its just that your browser
can make sense of the micro-format ;-)

Whatever you have your persistance teir configured with, you can just
layer lift on top for a REST service - it really is that easy.

Is it just a matter of documentation?  If so, I might be able to help
with
that.  When I am really interested in something, people praise me
very
highly for being explicit, easy to understand, and forceful.  I have
the
same feelings as Glen and Rintcius although I have great faith in
everything else that has been said.  If you gurus want to expand your
influence to the great unwashed masses, please see if
you can determine a time when you are willing to explain everything
to me at your location.

I am a genius, a Ph.D. and many other good things although I have a
learning disability, ADD, and other gifts which hold me closely to
the
masses.  I can't see this interoperability.  But if you will take the
time to
explain it to me as soon as I can come to visit you in person, I will
write
it up so that others can understand  it better/differently than your
current documentation.
Sincerely, Johnnie

[Lift] Re: Lift for non UI, xml REST server embedded in existing application?

[glenn]

What exactly are you looking for?
Are you looking for way to use lift to communicate with an existing
REST server, so that you can extract documents and display them
in your lift app - using lift as your blog interface?

If so, I'm trying to do something similar. There are discussions on
this
site from a lot of folks who say they are integrating lift with Jersey
and
other similar systems, but I haven't seen any code that directly gives
lift templates and snippets direct access.

You are correct, in that you can pretty easily create a REST server in
your lift application and GET xml documents from it, but I haven't
figured out
how  to PUT documents from a non-lift resource into my lift app, since
that
requires that you can somehow access lift's Req object via a URL

[Lift] Re: Redirect after login

[glenn]

David,

I was a little puzzled by the line, in the override of def homePage,
of loginReferer.remove(). This actually resets the homePage to "/".
Removing the line has the intended result. But, then I need a way
to reset the loginReferer session variable.

Better still, it would be nice to be able to create additional
stateful
parameter maps, something like Seam's conversation state, which
would make creation of wizards a breeze.

This brings up another point. The only way I trust to trace the code
to determine what's going on is the old-fashioned way, of putting in
a bunch of println statements in my code. With lift's flow back-and-
forth
between templates, which are really client-side, and snippets, which
are on the server, normal java debugging tools just doesn't work.

This makes developing a slow process and can even offset the gains
lift brings to coding efficiency.

What do you, and other's use for debugging that might help.

Thanks in advance for your assistance.

Glenn...

[Lift] Lift for non UI, xml REST server embedded in existing application?

[Barry Kaplan]

I'm looking for a bootstrap example of integrating lift into an
existing application that needs to server up XML documents via a REST
api.

The application is already operational and cannot be reconfigured to
live within lift -- I'm looking to lift to add just the http service
and infrastructure.

Does such a beast exist? (BTW, I have the lift book, but it seems only
to discuss adding an api to UI based lift application.)

thanks!

[Lift] Re: lift-webkit broken in 1.1-SNAPSHOT?

[Timothy Perrett]

Probably maven had a problem whilst downloading it - just blow away either
the net/liftweb folder in your .m2 or the whole .m2 dir and let maven
download it again.

Cheers, Tim

[Lift] Logging question

[TSP]

Does the lift logging framework support the classed based loggers that
are the normal use pattern:

Logger  logger = Logger.getLogger("com.foo");

and the class is automatically attached to the message.
If so how do you call it - with a direct java import or is there
something more lift-esque

Thanks

[Lift] lift-webkit broken in 1.1-SNAPSHOT?

[Mark Tye]

I've been using the 1.1-SNAPSHOT with great success until just now.
Maven just updated my lift-code dependencies, and now when I build, I
get this error:

error: error while loading Loc, class file '/Users/mtye/.m2/repository/
net/liftweb/lift-webkit/1.1-SNAPSHOT/lift-webkit-1.1-SNAPSHOT.jar(net/
liftweb/sitemap/Loc.class)' is broken
(bad constant pool tag 116 at byte 2819)
one error found

I see a new lift-webkit jar was installed in the repository at 17:30.
Is it possible the jar's corrupted? Is anyone else having this problem?

[Lift] Re: Lift and interoperability

[rintcius]

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).

Regards, Rintcius

I managed to fix the problem by changing  to
.

The question that still remains is why is this happening?
Summary: Naselja is a StatefulSnippet.
 -> new instance of Naselja created each time
"list" is rendered
 -> only one Naselja instance created

Why? Is it a bug? Is it by design and if it is where is it documented/
explained?
Thanks! :)
