[Lift] BSON support in lift-json
I finally had the opportunity to look into the couchdb code and I must say it is rather impressive. I would like to utilize the code in JSONRecord.scala in scamongo [1]. However, MongoDB uses a variation of JSON they call BSON, which they actually just published a spec [2] for, due to interest outside of MongoDB. Basically, it adds support for date, ObjectId [3], binary data, regular expressions, and code (JavaScript) data types. My question is, what would it take to add support to lift-json for these other data types? Is this even feasible?

Re: [Lift] BSON support in lift-json
I definitely agree with keeping the BSON code separate or possibly having a strict JSON mode.

Re: [Lift] setuid
Tamer, If you really want to run jetty on port 80, I would suggest using the iptables technique[1]. I used it before and it's pretty easy to get working and doesn't require jetty to run as root.

I am under the impression that a slight performance benefit offered by Apache would be offset by the bottleneck arising from double request handling (resulting in a reduction of throughput in comparison to direct requests to Jetty). Depends on what you serve a lot of. If it's anything but the page (i.e. css, js, png, img, etc etc), then you'll see better performance with Apache in front then jetty by itself. On the other hand, if you're serving mostly dynamic pages, then you won't see as much of a performance boost. However, ultimately, you're going to be better off putting Apache/Nginx in front. the performance concerns vs horizontal scaling options doing so are minor. A web server in front of the application server model allows you to easily add application servers to the mix. Running an application server alone won't do that. As with any talk of optimization, you should do it only when you have a problem. Thus, I would like the option to remove Apache down the road. In either case I would not want Jetty running as root. At this point its just an experiment, so I will try out a production scenario with Jetty server in the hopes that the issue with missing org.mortbay.setuid.SetUIDServer is due to building with Maven and using the plugin. Please let me know if you have a reason to believe otherwise. Thanks to all. I've never heard of a way to get a command line from the Java VM. The VM doesn't really work that way, and so gives you a layer of protection you don't have with a native app. http://math.hws.edu/eck/cs124/javanotes4/c9/s1.html is a nice summary of why. While Scala is not Java, it does run in the Java VM, using the compile Java Byte Code. Best, Tamer On Wed, Feb 17, 2010 at 5:16 PM, Timothy Perrett timo...@getintheloop.eu wrote: I would recommend using Nginx or similar up front and using a reverse proxy setup - it is the most optiomal solution as Nginx can handle a vast number more connections than Jetty so it makes scaling your app easier on a single machine.

Re: [Lift] Problems with SBT
sbt doesn't look at POMs. You need to create Project file and add the
dependencies in there.
The example in the following is a little old, but it shows what you need
http://code.google.com/p/simple-build-tool/wiki/WebApplicationExample
Here's an updated example:
import sbt._
class HelloLiftProject(info: ProjectInfo) extends DefaultWebProject(info)
{
val lift = net.liftweb % lift-webkit % 2.0-M1 % compile
val jetty6 = org.mortbay.jetty % jetty % 6.1.14 % test
// required because Ivy doesn't pull repositories from poms
val smackRepo = m2-repository-smack at http://maven.reucon.com/public;

Re: [Lift] (ISSUE) How to use the sbt with lift project ?
The jetty val you are overriding is an internal val that you shouldn't
be doing anything with. If you change that line to:
val jetty6 = org.mortbay.jetty % jetty % 6.1.22 % test-default
That part should work.

Re: [Lift] Re: (ISSUE) How to use the sbt with lift project ?
The lift-core dependency brings in every single lift module, even if
you aren't using them. I'd suggest you only use the ones you need,
instead. Also, I don't think the servlet dependency is necessary
anymore.
Try this for your project file:
import sbt._
class MyWebProject(info: ProjectInfo) extends DefaultWebProject(info)
{
val liftVersion = 2.0-M1
val liftwebkit = net.liftweb % lift-webkit % liftVersion %
compile-default
val liftmapper = net.liftweb % lift-mapper % liftVersion %
compile-default
val jetty6 = org.mortbay.jetty % jetty % 6.1.22 % test-default
// required because Ivy doesn't pull repositories from poms
val smackRepo = m2-repository-smack at http://maven.reucon.com/public;
}
This assumes you are using mapper. If not, you can remove that line.
You may also need to add other lift modules if you are using any of
them.
Note that mapper will actually bring in webkit for you, so it's
actually redundant in the example above, but I prefer to explicitly
set it.
Hth,
Tim

Re: [Lift] Problem with creating new project
I'm no maven expert, but I think you need to use generate instead of
create. See the warning halfway down, before the stack trace.
[INFO] [archetype:create {execution: default-cli}]
[WARNING] This goal is deprecated. Please use mvn archetype:generate
instead
Try:

Re: [Lift] Re: How to disable XHTML?
You need to remove the if guard on the first case match and change the
second parameter you are passing to Req. The second param is for the
context. Try this:
LiftRules.determineContentType = {
case (Full(Req(location :: maps :: testmap :: Nil, _,
GetRequest)), Full(accept)) = text/html; charset=utf-8
case _ = application/xhtml+xml; charset=utf-8
}

determineContentType is of PartialFunction[(Box[Req], Box[String]), String]

Re: [Lift] Jetty/Derby, unable to redeploy hot changes (FIXED)
I had the same problem while using H2. I solved it by disposing the db connections when the servlet is destroyed. I wrote a gist about it here: http://gist.github.com/166687 I don't think I've ever seen your solution, which might be a better way to handle it.

You can then either remove Derby as a regular dependency or put it as scopeprovided/scope so that Maven will not package it in your warfile. Is anyone else having this issue? Should I open a ticket in the issue tracker for the archetype? Maybe everyone knows to do this but it was annoying for a first timer like me who just started with the archetype, especially after the annoyance that archetype:generate menu generates an old archetype and won't upgrade to v1.0.

Re: [Lift] Re: How to configure two database connection in Lift?
I think there might be a problem with the way you are specifying which
db to use in your mapper classes. Here's the relevant text from the
The Lift Book:
dbSelect... is used to find an instance by primary key, and takes a
partial function (typically a match clause) to determine which
connection to use.
dbCalculate... is used when a new instance is created to decide where
to store the new instance.
Those 2 methods are used for sharding. Are you sharding? If not I
think you just want to override dbDefaultConnectionIdentifier

Re: [Lift] Re: How to configure two database connection in Lift?
I did some more digging and got a sample app to work. You can see the code here: http://github.com/eltimn/lift_1_1_sample There are 2 things I had to do. The first is to pass in the DbId when calling Schemifier; Schemifier.schemify(true, Log.infoF _, OneDB, User) Schemifier.schemify(true, Log.infoF _, TwoDB, Dog) This was the cause of the NPE earlier. The second thing I did was to create 2 separate DBVendor objects. I could not get this to work with one that matches on the ConnectionIdentifier, like the example in The Lift Book. I didn't dig into why this wasn't working, so it could be the way the code is written.

Re: [Lift] Re: how does lift work with redis?
I haven't used redis at all but it looks like they have a jdbc driver that you might be able to use with mapper. It doesn't support all jdbc functionality but it might work well enough for your needs. If that doesn't work you could either use the jredis java client code directly inside lift or use the record framework which is meant to be a mapper like framework for generic (ie nosql ) dbs. It, however, requires a back end implementation for each db system. Currently there is no back-end implementation for redis, so one would need to be written for it.

var stream: String = ;

[Lift] Re: record framework questions
Thanks David. Ticket has been filed: http://github.com/dpp/liftweb/issues/#issue/162 Regarding my last question about stability of the record files; I'm trying to decide if I should use the record framework and the back end implementation I wrote to build my website or if I should use the more basic framework I wrote. My main concern is having to make changes to my implementation if the record files are modified. Not that I'm against changes, I just want to plan ahead as much as possible. I realize that changes will always be a possibility and that you probably won't know more until you actually write the other back end implementations, I just want to get a sense of how you currently feel about them and what, if any, plans you have for the record framework in general.

[Lift] record framework questions
I have been working on a back end implementation for Record that uses MongoDB and I have a couple of quick questions; Is there a reason that valMinLen and valMaxLen were not copied into StringField? TimeZoneField has a companion object that has a list of the available time zones, it would be nice to have a similar companion object for LocaleField. How stable are the current Record, MetaRecord and Field* files? Are there any plans to make any changes to these?

[Lift] Re: Why fields are declared as 'object' with Mapper/Record?

wrote:
I don't care for the pattern, but it comes from Scala history... so
In the days of Scala 2.3, an inner object had different class and method
visibility than a val instantiated in the same way. So, if you had:
object foo extends Object { def bar = You can call me
}
You could call bar. However:
val foo = new Object { def bar = You can't call me
}
foo would be an Object, not visible as a subclass of Object. So, that's
the first reason for object vs. val.
The second reason is that it's possible to disambiguate:
object foo extends MappedString(this, 32)
from
var foo: MappedString[OtherThing] = _
It may be possible to disambiguate these now, but in the 2.3 days, it
wasn't.
It sounds like both reasons for using objects are legacy related. Is there
any reason (other than time constraints) to not update the Record framework
to take advantage of the newer language features?

Hi all,
Building off of a previous thread[1], I'm trying to parse a POST
request that contains JSON data. Specifically, I expect a JSON array
of JSON objects representing Packet model data and want to have a List
[Packet] at the end.
I am trying the following:
val packets = for {
JSONPackets - req.param(packets)
packet - JSONParser.parse(JSONPackets)
nodeId - packet.param(node)
node - nodeId.toLong
} yield {
val packet = Packet.create.node(node)
packet.save
packet
}
The problem is that JSONParser.parse returns a List[Any], so packet is
of type Any. I can try to convert packet to a Map with
packet.asInstanceOf[Map[String, String]], but this seems to just push
my type problems to the next line of code. I'm having a hard time
getting to the point where I have the Map[String, String] from which I
know I can extract values to create Packets, so I would appreciate
suggestions on how to do this.
This all seems quite complicated and I wonder if I'm missing an easier
way to do this. Is JSONParse the way to go, or should I switch to
Joni's lift-json stuff? I'm using 1.1-M5 but would be willing to
switch to 1.1-SNAPSHOT...
Thanks for your help.

[Lift] Re: URL rewriting woes
Paul,
The basic problem here is that whatever you put in the RewiteResponse must
be in your SiteMap. So, to get a url like /customer/list/1 to be rewritten
to /cust.html?page=1
you would need:
Menu(Loc(Customers,
cust::Nil, Customers))
in your SiteMap. Doing this however means that your menu link will be /cust
and you would have to manually generate your links.
I am running into this same problem and haven't figured out how to handle
it yet.

Hello again,
I've been looking at the article on URL rewriting at [1] and am having

My sitemap contains Menu(Loc(Customers,

gives a link to /customer/list/1.
My rewrite is:
LiftRules.rewrite.append {
case RewriteRequest(ParsePath(customer::list::page::Nil, _,

RewriteResponse(cust :: Nil, Map(page - page))
}
so clicking on /customer/list/1 should show cust.html and give me a
page parameter. The cust.html file exists.
Unfortunately I get The Requested URL /customer/list/1 was not found

Do I need to do anything else to get this to work?

[Lift] Re: Another backtrace on reload
I just read your original post and that error is exactly what I was referring to in my last post. The problem is, by default, the database shuts down when the jvm shuts down. So, if you want to dynamically restart jetty, you need a way to shutdown the db if the jvm is not shutown. You can do as I described in my last post, using sbt, but there are other options. I'm not sure if that will work with mvn. H2 comes with a DbStarter [1] ServletContextListener that will start up and shutdown the db. It can also start up a tcp server, if you need that. However, it requires you to specify the db url, user, and pass as context-params. Which is a show stopper for me. There is only one line in DbStarter that one would really need and that is a sql statement that is sent to the db. This code is in the contextDestroyed method. So, if there is a way in Lift to call some code when the servlet context is destroyed, then one could put that sql statement there and manually shutdown the db. I realize you use Derby, but I'm guessing that it works similarly. So, Lifters, is there a way to call some code when the context is destroyed? Or, is there another way to accomplish this?

I just saw that the other day. The problem is those pages aren't being
wrapped by the default template. In newer versions of Lift there is a
default screenWrap, but 1.0 doesn't seem to have it.
In order to add the wrapper, you need to add lines similar to the following
to com.pocketchangeapp.model.User.scala
override def changePasswordXhtml =
lift:surround with=default at=content
div id=formBox{ super.changePasswordXhtml }/div
/lift:surround
That fixes the change password
page. You'll need to look at the source of ProtoUser to see the other
page names:

[Lift] Re: Unique constraint
H2 has a great console servlet that you can use to connect to any jdbc
compliant database and I just figured out how to configure it to work with
lift.
Assuming you already have H2 as a dependency, just add a mapping to the
servlet in your web.xml. Mine looks like this:
web-app
filter
filter-nameLiftFilter/filter-name
display-nameLift Filter/display-name
descriptionThe Filter that intercepts lift calls/description
filter-classnet.liftweb.http.LiftFilter/filter-class
/filter
filter-mapping
filter-nameLiftFilter/filter-name
url-pattern/*/url-pattern
/filter-mapping
servlet
servlet-nameH2Console/servlet-name
servlet-classorg.h2.server.web.WebServlet/servlet-class
load-on-startup1/load-on-startup
/servlet
servlet-mapping
servlet-nameH2Console/servlet-name
url-pattern/console/*/url-pattern
/servlet-mapping
/web-app
Then you need to add a rule to LiftRules.liftRequest using the following
line in boot:
LiftRules.liftRequest.append({case r if (r.path.partPath match {case
console :: _ = true case _ = false}) = false})
That basically allows all requests that start with console to be ignored
by lift and passed thru to the servlet.
I am actually using PostgreSQL, but I prefer using this to pgAdmin or other
SQL tools.
