I'm sorry for the double post

[Christian Thomas]

Hello,

I'm sorry for my double posts ( creating a new theme ). After creating the new theme the first time, I was wondered, that it was not created. That's why I have created the theme twice (headline: Jump start for creating a lift 2.5 web-app base project with maven) . After that I have read the hint:

Thank you : )


Kind regards!

Jump start for creating a lift 2.5 web-app base project with maven



Hello Lift community,

I'm a JEE developer and I'm looking for a cool and powerful web-framework, which can use my JEE business/backend components (should be simply possible with an JNDI lookup of my EnterpriseJavaBeans). So I found the liftweb.net page and I'm really interested in using the Lift framework (because it is flexible as rails, grails, etc. - I need no persistence-layer from a web-framework, while this already exist's in my JEE environment ).

My aim:
- create a base-lift project using maven instead of the sbt ( it should be integrated as a module into an existing maven-project later on )
- I would like to use the lift 2.5-M2 version
- I would like to use the scala version 2.9.2
- with that base I want to learn the power of lift (by reading the exploring.lift /simply.lift books)
- in addition I also have to learn scala ( that should not be a big problem )
- create a REST interface, that should be used from lift itself, but also give the chance, that another client (like an android-app/ iOs app) can use the interface. Business objects should interpreted/mapped/converted as JSON objects for client's
- I'm using a JBoss AS 7.1 app-server. I think it should not be a problem to deploy the lift-war file to the jboss instead of a jetty server. If not, then a jetty will be used for the web-client.

My problem:
At the moment it is hard to create a simple base web-app structure. Beside the simply-lift book I've started to read the exploring-lift book.

But following does not work ( Exploring Lift ) :
Next, we use Maven’s archetype:generate command to create the skeleton of our project:
mvn archetype:generate -U \
  -DarchetypeGroupId=net.liftweb \
  -DarchetypeArtifactId=lift-archetype-blank \
  -DarchetypeVersion=2.0 \
  -DarchetypeRepository=http://scala-tools.org/repo-releases \
  -DgroupId=demo.helloworld \
  -DartifactId=helloworld \
  -Dversion=1.0-SNAPSHOT

it will be created, but the following part

Maven should output several pages of text. It may stop and ask you to confirm the properties configuration, in which case you can just hit <enter>. At the end you should get a message that says BUILD SUCCESSFUL. You’ve now successfully created your first project! Don’t believe us? Let’s run it to confirm:
cd helloworld
mvn jetty:run

does not work.

 mvn jetty:run

My next try is to call a mvn install (I think it should be executed, before I can start the jetty), but that doesn't work, too. It will return the same error above.

It's a pity. ( In addition this is not a solution to use newer releases of lift / scala )


Then I have downloaded the lift tar, which includes the different base projects of lift. They are all configured for the sbt.

Should I use the blank project, remove all sbt artefacts and create a own pom.xml? But then the big question is, what are the required dependencies, what do I have to configure? ...

I hope, some of you can help me, what I have to do, to create a lift-2.5/scala 2.9.2 blank web project with maven. Or can give me a base pom.xml, which can be used for an own project.

Thank's a lot! : )

Kind regards!
Christian

Sorry Christian, I was finishing a SOF answer when the email for moderation came in my mail box!

One of the twice created threads I've deleted.

May you can remove this message here ( "I'm sorry for the double post" ) too. Then everything is fine.

Thank's!
