problem getting sbt 0.11.2/Lift 2.4/Jetty initially set up

[Toby Thain]

Hi,

Not really a Lift problem but more an sbt/Jetty problem, but hoping someone here might have hit this and knows how to solve it.

Running sbt I see this:

[info] Resolving org.eclipse.jetty#jetty-webapp;7.6.2.v20120308 ...

Which appears to be this problem:
http://stackoverflow.com/questions/9889674/sbt-jetty-and-servlet-3-0

But the ivyXML workaround posted there doesn't work for me.

Anyone solved this?

The dirty but easy solution would be to download the jar, create a lib folder at the root of your project and place the jar there.

I also had many problems with eclipse, did you try it with maven?

It works simple without problems. Also tell me if you have syntax problems in eclipse I got solutions for that which are hard to follow if you research them.

Thanks for the replies, everyone.

I did get this working, but only with Jetty 6. Here is my build.sbt with the working configuration. Commented out are the configurations which fail (Jetty 7 and Jetty 8).

I also had same problem with the latest 8.1.2, but the 8.1.0 makes no trouble, try:

"org.eclipse.jetty" % "jetty-webapp" % "8.1.0.v20120127" % "test, container", // For Jetty 8

I did get this working, but only with Jetty 6.

Since I am deploying with Jetty, is there a way I can import Jetty utility classes from my Lift project? A simple import does not find the package; obviously I am new to Java deployment—is there some step I need to take to make this possible?

You are quite right. This works fine! Thanks.

[Diego Medina]

which jetty utilities are you trying to use?
You would normally have to add the correct dependencies to your
project, if you are using SBT, there is a build.sbt or build.scala
file you would need to modify, if you are using maven, you modify a
pom.xml file.

My build.sbt is described above. The Jetty container is working fine. I am just wondering how I can import a class from Jetty, e.g.

org.mortbay.util.UrlEncoded

I'm not sure how you see this email thread, but I just saw one email and no sample build file.

I want to help you but I don't think it's fair for me to have to go and search the mailing list to see where your build file  went.

Apologies; libraryDependencies look like this:

libraryDependencies ++= Seq(
  // see http://docs.codehaus.org/display/JETTY/Downloading+Jetty for Jetty versions

  "org.eclipse.jetty" % "jetty-webapp" % "8.1.0.v20120127" % "container",
  //...
)

Hi,

Ok, if you want to access
org.mortbay.util.UrlEncoded
you cannot use

"org.eclipse.jetty" % "jetty-webapp" % "8.1.0.v20120127" % "container",

because org.mortbay is jetty until version 6

So, you will have to downgrade to jetty 6 or see what the new name is
for jetty 8.1
I think the new name is
org.eclipse.jetty.util.UrlEncoding
so try using that name, if that import does not work, you need to add
a dependency that has that class.

Just guesing here, but you can try adding

"org.eclipse.jetty" % "jetty-util" % "8.1.0.v20120127" % "container",

do your build file and run sbt update.

Regards,

Diego

Right, my initial experiments were with v6, then I got v8 working later for the webapp.

That sounds like the missing piece of the puzzle! Thanks, I'll try it.

Never mind - it does work. The "configuration" part did not match the configuration I was running. By using dependency:

  "org.eclipse.jetty" % "jetty-util" % "8.1.0.v20120127",

I can import the class and run in default configuration (sbt run).

Thanks for the help!

Hello, 

I have got a similar problem trying to import my project in eclipse (I created it using "sbt> eclipse with-source=true").

In the file "RunWebApp.scala", the four imports are refused:

import org.eclipse.jetty.server.handler.ContextHandler

import org.eclipse.jetty.server.nio.SelectChannelConnector

import org.eclipse.jetty.server.{Handler, Server}

import org.eclipse.jetty.webapp.WebAppContext

Here are my library dependencies:

"net.liftweb"       %% "lift-webkit"        % liftVersion        % "compile",

    "net.liftweb"       %% "lift-mapper"        % liftVersion        % "compile",

    "net.liftmodules"   %% "lift-jquery-module" % (liftVersion + "-1.0"),

    "org.eclipse.jetty" % "jetty-webapp"        % "8.1.7.v20120910"  % "container",

    "org.eclipse.jetty.orbit" % "javax.servlet" % "3.0.0.v201112011016" % "container" artifacts Artifact("javax.servlet", "jar", "jar"),

    "ch.qos.logback"    % "logback-classic"     % "1.0.6",

    "org.specs2"        %% "specs2"             % "1.12.1"           % "test",

    "com.h2database"    % "h2"                  % "1.3.167"

Do you know what I have been missing? I created the project using https://github.com/lift/lift_25_sbt and imported it in Eclipse. It is the first time I use eclipse for a Lift Webapp so I don't have any idea :-/. I can run my Webapp using "sbt> container:start" and see it in the browser without any problem.

Thanks in advance!

When you find yourself in a case like this, where the IDE tells you
there is a problem, but sbt runs fine, then it is an IDE bug
I don;t know where you would report those bugs, (I use Intellij, and
I love it :) )

Okay, I had heard some people saying that they were loving Eclipse for Lift =). I'll maybe try IntelliJ then!

Yes, you will find people loving eclipse, emacs, vim, etc :) What I
like ab out intellij is the maintainer really fixes issues as we find
them, basically, if you run into some code marked as error that is not
a real error, you can report them on
http://youtrack.jetbrains.com/issues/SCL
post a link here on the list, so we all vote on the issue and some
time later the fix should magically appear :)

Hi Jones

First a quick note: You are not required to use the functionality of RunWebApp.scala to integrate your Scala/Lift work into Eclipse.

I use eclipse for all my java/scala projects but when It comes to running lift/scala apps I mostly do it from within sbt (with jrebel) but if you prefer you can just as easy run it from within eclipse.
When I need to dig deeper and debug the app I run from within eclipse with the use of the RunJettyRun eclipse plugin. See [1] for more information it's really simple to set up.

Generally when you want to work on a Lift app with the use of Eclipse IDE you start by import the lift project into eclipse (ones)

Here is the 2 steps for the initial setup:

1) Start sbt and run the eclipse command to create project files.
project$ ./sbt
> eclipse

2) Now in Eclipse menu ..
File ==> Import...
Select General ==> Existing Project into Workspace
Use "Brows" to look up the project root ....

Most of my github projects includes this step information in the "Scala IDE for Eclipse" section in the readme.md file in [1] or any of my other github projects (they generally includes this information).

[1] http://higherlogics.blogspot.se/2012/03/debugging-lift-24-with-eclipse.html 

[2] https://github.com/karma4u101/Templating-With-Twitter-Bootstrap

best regards

[Peter Petersson]

... and of corese (I forget to mention) when you are working with Scala in Eclipse you need the Scala ide plugin for eclipse [1].

best regards

[Olek Swirski]

I think, that you may get the error, because you try to:
import org.eclipse.jetty.webapp.WebAppContext
but in your sbt file jetty-webapp is in "container" configuration,
but not in compile configuration, so will be available when your jetty
is used by sbt to serve your app, but not during compilation. I think
using "container,compile" instead should fix your problem. It works
for me and I can do the imports you listed.
