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:
New Member Policy: New members are moderated.
Please be patient after posting, your message may not show up

So please ignore one of the new themes / threads.
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
