WSO2 App Factory v1.0.0 M8

Recently WSO2 App Factory team released their 8th mile stone[Release mail]. This may be the pre alpha release.You can down load preconfigured VM from here.
Lets look at the new features of this release briefly.

1. Now users can create applications either with svn or git repository:In the VM a Apache server based svn deployment and Gitblit based git deployments are available .User can select preferred repository type while creating application.The Jenkins job also will be configured automatically according to users' selected repository type.

2.Integration of Human Task:While user submit registration from we can configure App Factory to fire a human task to get approval from an admin.This feature is valuable in the environment where strict approval process is needed. Refer this blog post for further information. 

3.New Gadgets:There are two new gadgets to view application event stream and search applications.

4.Log download:There is a way to download logs from build ui. App Factory uses WSO2 Stratos logging frame work to collect and display logs.With this release log download links is provided.

5.Improved Build and Deploy model:Ability to tag a build is provided and the default artefact storage is moved into Jenkins side.There is a REST api is exposed from the Jenkis to deploy a built artifact to a server.All the Jenkins plugins are merged into one "appfactory-plugin" and fixed some problem while deploying Jenkins in master slave mode.

Ok ,now the time to look at some new features that may come with next(probably Alpha) release.

 *Integration with GitHub :There will be Github based repository provider.
 *Artifact deployment with WSO2 Stratos 2 : Final Artifact deployment model will be with WSO2 Appserver Cartridge cluster.WSO2 recently released Stratos Alpha,this is a completely different cloud Linux lxc container based architecture.
*And more..
That's all  for now ,Wait for next release...

Creating SVN Repository Remotely

Linux distribution of Apache subversion provides svnadmin to create a svn repository.But this is not capable of creating repository remotely.By issuing svnadmin command we can only create a repository within local file system.
Here i am going to describe couple of ways by which we can create svn repositories remotely.Here all my ways achieve above mentioned objective through  java.Here is the list of method that i found.

1.Using ssh to execute svnadmin command remotely.
    a)Using apache sshd library
    b)Using JSch library
2.Using SCM -Manager
3.Using PHP+java Client

Using ssh to execute svnadmin command remotely

In this approach the repository is created by executing svnadmin or relevant command in remote host using ssh.Here there are two ssh opensource libraries available for java.

a) Using apache sshd library

apache sshd is a pure java implementation of ssh available under apache 2.0 license.This is a sub-project of apache Mina.Here is a example code for executing svnadmin command on remote host as a superuser.

To use apache sshd library you have to add following maven dependency. 

b)Using JSch library

This is another popular java implementation of ssh.There are  good examples also available for this libarary.Here is how to execute svnadmin command using JSch library.
Following is the maven dependency which can be used to create maven project.

Using SCM -Manager

Next approach is using a source code management system.SCM Manager is an open source source code management system which is implemented in java.This is
a server which provide user interface to create repository and manage them with users.Currently it support svn ,git and mercurial.In addition to user interface, it expose REST API to manage repositories.Here i am going to use the REST API to create a repository.Before staring writing the REST Client Download the SCM Manager from here and start the server by executing the script which can be found in bin folder of the distribution.
To write the REST client there so many ways.
  1.Using HTTP client
  2.Apache Wink client
  3.Jersey Client
I am using http client wich is very simple to use.All the REST calls are protected by BASIC Auth in SCM  Manager.We have to set the credential in http client.
Here i used Axiom for generating XML payload.

Using PHP+java Client

In this approach a php page that is hosted in apache 2 server in remote host will create a svn repository using svnadmin command and there will be a java client that is used to call the php.The php page is secured using Basic Auth.Here is the very simple php code to create svn repository.

Here is the java client that is used to call the php page.
This is how we can create svn repositories remotely.This will be helpful when ever there is a requirement of automatic repository provisioning.

Getting Started with WSO2 Appfactory VMware Image

In this post i am going to describe how to getting started with WSO2 Appfactory VMware image first mile stone  release.

WSO2 Appfactory

WSO2 Appfactory is a new solution that provides a convenient environment to manage Applications between different stages of development.For example each application developed in enterprise goes through so many stages (such as dev and QA)before going to live.While it is moving between stage it goes through so many reviews(such as security review and policy review) by different users and authorities.WSO2 Appfactory provides a convenient and easy to use environment to manage application between different stages.For more information on WSO2 Appfactory refer following blog.

WSO2 Appfactory VMware Image(M1 release)

WSO2 Appfactory team recently released their first appfactory milestone release as a VMware image.The image has following servers
1.WSO2 Appfactory
2.WSO2 Stratos Manager
3.WSO2 Application server (for each stage(dev and live))
4.SCM manager
All the servers are connected to a single LDAP and a remote  governance registry
Following diagram shows the deployment pattern that the image uses.

Now lets play with this image.


1)VMware player should be installed in 64 bit machine with visualization enabled.
2)The host machine should have at least 4 GB memory and connected to Internet.

Getting Started with vm

1)Download the image from
2)Unzip the downloaded file.
3)Start the VMware player.
4)Open the image as following

5)Edit the image setting as follow

Increase the memory to at least 2 GB(Recommended ~8GB)  and enable bridge network setting.
6)Start the image

use following credentials to login to the image.
User-name: appfactory
Password: appfactory

1.Change the /etc/hosts entry of to
2.Change keystore location of scm manager.
Open the carbon-auth.xml that can be found in /home/appfactory/final-zip/scm-server/repository/config.
Change the keystore location to /home/appfactory/final-zip/appfactory/wso2appfactory-1.0.0-SNAPSHOT/repository/resources/security/wso2carbon.jks

7)Start all the servers as back-end process.
Start Appfactory
cd /home/appfactory/final-zip/appfactory/wso2appfactory-1.0.0-SNAPSHOT/bin
nohup ./ &
Start Stratos Manager
cd  /home/appfactory/final-zip/cloud-manager/wso2stratos-manager-2.0.0-SNAPSHOT/bin
nohup ./ &
Start Dev cloud Application server
cd /home/appfactory/final-zip/dev-cloud/wso2as-5.0.0-SNAPSHOT/bin
nohup ./ &
Start Live cloud Application server
cd /home/appfactory/final-zip/live-cloud/wso2as-5.0.0-SNAPSHOT/bin
nohup ./ &
Start SCM Manager
cd /home/appfactory/final-zip/scm-server/bin
./scm-server start
8) Get IP address of the VM and enter following to /etc/hosts of the host.
In VM issue sudo ifconfig and get the IP.

Add above entries to /etc/hosts of host machine.Here change the IP address as you got in previous step.
Wait for some time to start all the servers success fully then you can access the servers using following link in host machine browser.
Access Appfactory
Access Dev cloud Application server
Access Live cloud Application server

Getting started with Appfactory

Now it is the time to create a application and deploy it to cloud.
1.Register a new user
 2.Register a user by clicking sign up button at left top of the sign in page as follow.
Fill the sign up form

Check your mail  and click the link sent by mail to validate the email address.

2.Create an App
 Login as created user
By clicking add apps create new app
After successful creation of application it will display the created SVN url.
 When ever user login he always see the list of applications with short details
When the user click on a app depending on the role of the user he will see different dashboards.
All the member can view the dev-view as follow.
The users in admin role can view admin view.The admin user can invite already registered users to application.

The user in devOps role can view devOps view.Here he can deploy the application to stages(dev or live).

3.Invite a user as a developer
Register a new user.
Invite him as a developer to created project.

4.Invite a user as devOps
Same way invite another user to devOps role.
5.Commit a CAR project into svn as developer
Check out the svn repository  displayed on dev-view as developer.
Add a car project  to the checkout directory(use following car project)
Commit the project

6.Login as devOps and you can
              -deploy to dev
              -deploy to live in dev-ops view.

7.Then finally you can check the relevant application server in cloud for the deployed application.
Login to
as the user who created application using user name as {user-name}@{application-id} and check the deployed car applications.

Thats all for milestone one release.I hope wso2 appfactory will come with more functionality with less distribution size in future releases.
