I had deployed the app last on friday and it got deployed successfully.But since, today morning the deployment is not happening at all.It is checking for conflicting process and failing.
I'm doing this from the webide and i'm not able to check what are the conflicting process and how to resolve it.
WebIDE lacks the ability to do proper investigation on deploying apps to SAP Cloud Foundry.
The best way to do this is to install the Cloud Foundry Multi-apps plugin (see this tutorial). This will allow you to use the local terminal to control the deployment (or alternatively use SAP Business Application Studio which already has the commands built in).
Then use the command cf mta-ops to get the list of ongoing operations and cf dmol <operation_id> to download the logs for that operation. cf deploy can be used to abort/retry operations.
I tried to launch our Scala application on the Swisscom Cloud Foundry (CF) infrastructure. To do so, the matching Heroku buildpack was used:
https://github.com/heroku/heroku-buildpack-scala
As this did not work, I tried to deploy the 'hello-scala' example using this buildpack.
My fork to be able to build the slightly outdated example:
https://github.com/AlwinEgger/hello-scala
I have to underline that I am fetching the port I have to use as env variable 'PORT'.
Unfortunately, there is not much on the log. "failed to accept connections within health check timeout" message indicates that there is no one listening...
My questions: Did anyone succeed in deploying Scala apps on CF infrastructures (# Swisscom)?
A workaround I found:
I'm not using the scala- but the java-buildback. This with the major advantage and inconvenience that the project is not any more build on the instance.
Advantage: It speeds up the whole process considerably
Inconvenience: A build server is needed
So what do we have to do?
An example may be found here (this is the actual application):
https://github.com/OpenOlitor/openolitor-server
Add the sbt-native-packager to your project
Execute the action 'universal:packageBin' building by hand or configure your build server to do so
Change the buildpack in the manifest.yml and add some parameters, if necessary. Configure the path of the artifact to deploy.
Run cf push or let the build server do so.
Been googling around for some time already.
I have some java, nodejs, php, etc. applications deployed in openshift, and I want to deploy a scala play2.3 app now. I'm starting a new project and I really want to write it in scala with play.
I need either a way to deploy a play 2.3 app in openshift, or another free hosting service that provides the same tools.
Thanks in advance!

as i know Heroku hosting service let you deploy scala-play application. also it seems that OpenShift also provides the same functionnality.
You may try following QuickStart: https://hub.openshift.com/quickstarts/198-play-framework
I packaged my Scala/LiftWeb app with the sbt one-jar plugin into a single executable jar file and packed it up with Docker, exposing the embedded Jetty's port in the Dockerfile.
It runs fine locally on Docker and appearently deploys clean on AWS EB using the CLI deployment tools. On the received EB URL however, all I see is the congrats page saying "Your Docker Container is now running in Elastic Beanstalk on your own dedicated environment in the AWS Cloud.".
So, where is my app? Do I miss any steps making my app publicly available on my EB instance?
For future reference, the problem was caused by using an obsolete 2.x version of the aws-eb-cli tools package. Upgrading it to 3.x made the error obvious - building the docker image has failed on AWS.
What I was looking for was running an existing docker image, I found instruction for this scenario at https://aws.amazon.com/blogs/aws/aws-elastic-beanstalk-for-docker/.
Thanks a lot for Nick for asking the right questions which made me realize the obsolete tools package!
I love Heroku but I would prefer to develop in Scala rather than Ruby on Rails.
Does anyone know of any services like Heroku that work with Scala?
UPDATE: Heroku now officially supports Scala - see answers below for links
As of October 3rd 2011, Heroku officially supports Scala, Akka and sbt.
http://blog.heroku.com/archives/2011/10/3/scala/
Update
Heroku has just announced support for Java.
Update 2
Heroku has just announced support for Scala
Also
Check out Amazon Elastic Beanstalk.
To deploy Java applications using
Elastic Beanstalk, you simply:
Create your application as you
normally would using any editor or IDE
(e.g. Eclipse).
Package your
deployable code into a standard Java
Web Application Archive (WAR file).
Upload your WAR file to Elastic
Beanstalk using the AWS Management
Console, the AWS Toolkit for Eclipse,
the web service APIs, or the Command
Line Tools.
Deploy your application.
Behind the scenes, Elastic Beanstalk
handles the provisioning of a load
balancer and the deployment of your
WAR file to one or more EC2 instances
running the Apache Tomcat application
server.
Within a few minutes you will
be able to access your application at
a customized URL (e.g.
http://myapp.elasticbeanstalk.com/).
Once an application is running,
Elastic Beanstalk provides several
management features such as:
Easily deploy new application versions
to running environments (or rollback
to a previous version).
Access
built-in CloudWatch monitoring metrics
such as average CPU utilization,
request count, and average latency.
Receive e-mail notifications through
Amazon Simple Notification Service
when application health changes or
application servers are added or
removed.
Access Tomcat server log
files without needing to login to the
application servers.
Quickly restart
the application servers on all EC2
instances with a single command.
Another strong contender is Cloud Foundry. One of the nice features of Cloud Foundry is the ability to have a local version of "the cloud" running on your laptop so you can deploy and test offline.
I started working on the exact same thing as what you said a few weeks ago. I use Lift, which is a great framework and has a lot of potential, on top of Linux chroot environment.
I'm done with a demo version, but Linux chroot is not that stable (nor secure), so I'm now switching to FreeBSD jail on Amazon EC2, and hopefully it'll be done soon.

There are also other Java hosting environment including VMForce mentioned above.
If you are looking for a custom setup which also has the ease of deployment that heroku offers: http://dotcloud.com. They are invite only right now but I was given access in under three days. I am working on a Lift/MongoDB project there and it works well.
Off the top of my head, only VMForce comes to mind, but its not available yet. This will be a Java-oriented service, so that probably means you'll have to spend a wee bit of time figuring out how to package the app.
For more discussion, there was a debate about this in 2008.
I'm not entirely sure if it's really suitable or not, but people have deployed Scala applications to Google App Engine, for example http://mawson.wordpress.com/2009/04/10/first-steps-with-scala-on-google-app-engine/
Actually you can run scala on heroku right now. You don't believe it?
https://github.com/lstoll/heroku-playframework-scala
I'm not sure the tricks lstoll has used are legit but using the
new cedar platform where you can run custom processes and some
ingenious Gemfile hacking he has managed to bootstrap the Java
play platform into a process. Seems to work as he has a live
site running a test page.
Stax cloud service offers preconfigured lift project skeleton. Also, there is a tutorial on how to deploy lift project to appengine.
