I would like to deploy 3rd party libraries to help with the logic in my chaincode. How can I deploy these libraries to Hyperledger on Bluemix? I have successfully deployed chaincode without libraries, but now would like to try with libraries. However, the examples I've seen only point to a github directory with the chaincode go file and nothing else. Any help is appreciated.
I suspect vendoring all the dependencies would work well. It has for me in the past.

I am trying to set up a rest API that is connected to an IBM blockchain resource. I have developed a model file, logic file, and acl file.
I have it all packed up in a nice tidy .BNA, and now i would like to deploy it to a channel of my IBM cloud blockchain 2.0 resource, running on a free kubernetes cluster.
Everything on the cloud blockchain resource is set up perfectly, and all orgs, peers, orderers, msps, and CAs are set up correctly. The channel is set up properly, and has nodes and an MSP connected. I have all the admin cred .jsons
The channel only accepts smart contract files, so I tried repackaging the files (logic.js, permissions.acl, and model.cto) by putting them in a contract folder, and using the IBM Blockchain vsCode plugin to package them as a smart contract, but trying to install on the IBM cloud crashes the browser.
I am thinking maybe I have to remote connect into the IBM kubernetes cluster that the blockchain resource is sitting on, and use the hyperledger composer CLI to install the .BNA
Seems very unintuitive, but thats the one thing I can think to try while I wait for this question to get answered.
I expected to just be able to install the .BNA as a smart contract, like a .cds.
In August 2018, IBM announced that we are no longer investing in Hyperledger Composer, and instead focusing 100% on Hyperledger Fabric. As a result, IBM Blockchain Platform v2.0 will not provide any support or tooling around Hyperledger Composer.
The good news is that we've significantly invested in the programming model (APIs and SDKs) used to write smart contracts and applications in Fabric v1.4, and we've also released some great developer tooling in the form of an extension for Visual Studio Code: https://marketplace.visualstudio.com/items?itemName=IBMBlockchain.ibm-blockchain-platform
The extension offers an extensive set of capabilities for writing smart contracts - with tooling for creating new projects, packaging them, deploying them, testing them, and debugging them - all from within one of the most popular IDEs around.
To get started - just install Visual Studio Code, and then the IBM Blockchain Platform extension (there are a few prereqs, check the README first). After that, you will be presented with a homepage that links you to tutorials and samples to help you get started.
For the first one, I can't really suggest a solution. At best, try installing and using the composer CLI and the latest version to make the bna file. Composer playground isn't maintained as well imo.
For the second part, in the connection.json file and docker there will be a bunch of IP addresses that look something like localhost:7040 and so on for the CA, orderer, org and peer. You will need to replace these using the IPs given by IBM. The examples on github that demonstrate integration are to do with nodejs SDK and not composer, however you can refer to https://github.com/IBM-Blockchain/vehicle-manufacture to get the idea.
This link is the only I could find for Hyperledger Composer and IBM platform.

Can Bluemix environment with Liberty be replicated on developer laptops for offline development? Will I be able to run Bluemix local with Openstack on a quad core i5?
You can run Cloud Foundry in a VM on your laptop using bosh-lite. You could also install the open source Liberty buildpack into this local CF with the buildpack dependencies cached giving you an environment that could work offline.
The Bluemix services will not be available to you though, if you are offline, so the answer really depends on what services you need. You could reasonably set up some kind of local database but many of the services would just be unavailable.
I am not sure what exact your requirement is. IBM Liberty profile can be setup with Eclipse and you can create a server in local to test your java/JEE code. This is very simple, you need to install liberty plugin in Eclipse and create a server. See documentations in IBM web site.
See this url if it helps.. you can integrate BlueMix server to your Ecplise IDE

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!
Regards
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 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

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.
We have recently added some functionality to our web site that requires adding a service reference to an api in an external domain. Adding the reference to a VS2008 project createed a sub-folder in the "Service References" folder and added 18 files to that folder that appear to represent the classes in the api. The api provider also had me add custom binding and client references to system.serviceModel in my web.config file.
Do I have to deploy that entire folder with its 18 files to my production site to use the web service? Does some of it get compiled into my project dll? I can find all kinds of references to deploying a service, but not what is necessary to deploy a service consumption module.
Sorry for short, but I don't have the answer for you. But you can get this answer yourself. This is the only way Iwould get the answer. Deploy it without them, see if it works. If it doesn't deploy with. If it works, then you know.
The good news is that I have to deploy absolutely no files from the project have to be deployed to the production site. Everything the web service consumer application needs gets compiled into the application assembly.
