WSo2 Platform

Challenges in Enterprise Software
Legacy Modernization and Integration
Most enterprises have complex existing systems that are expensive to replace and need to be connected to web applications and new business processes
End-to-End Flows, Straight-Thru, Business Processes, Portals
Enterprises need to reduce human interaction as much as possible to make transactions efficient
When human interaction is required, it needs to be high-quality and contextual (portal, task list, analysis data available)
Performance, Scalability and Reliability
For Straight-Through-Processing and consumer-fronting applications there needs to be very high scalability and performance
Skills
There is a shortage of people required to build very high performance, complex, integrated applications. Simple effective systems with clear programming models are vital
Governance
Large enterprises have thousands of applications that need to be tracked, with lifecycle and dependency management
Identity Management
Need to integrate Web-based Identity management and federated identities
A strong move to Policy-based authorization and entitlement with central management

WSO2 Carbon, The webapp
Carbon can be used as an standalone server or can be deployed in application servers.
Carbon is itself a webapp, hence In the standalone mode, it uses an embedded tomcat instance.
In both modes, Carbon is launched by the BridgeServlet which bridges the non-OSGi world and the OSGi world.

What is a Carbon Component
A set of OSGiBundles.
Lives in the Carbon Framework. Hence should conform to rules define in the Carbon Framework.
Two aspects/ BE-FE Separation
Every component has a core runtime, a clean SOA management interface, a well-defined front-end console component
Back-end Runtime
Front-end Console
Uses Core Carbon Services
Via OSGi service registry
e.g. Registry Service, UserManager Service, etc.

What is a Feature
In Eclipse world
Feature is a grouping of set of logically related plug-ins/ OSGi bundles
Feature can be installed into Eclipse platform using its Update Manager
In Carbon world
Feature can be thought of as an installable form of one or more logically related Carbon component
Service Management Component
What you develop
Service Management Feature
What you install
Feature is a grouping of one or more logically related Carbon components
Features can be installed into Carbon based product using Feature Manager

Features
Allows you to specify pre-requisites of your Carbon component.
Other dependent features, bundles.
Dependency Management.
Are installable Units which can be installed into any Carbon based product.
Can be install using the WSO2 Carbon Feature Manager
Can be shared with others by packaging features as a Repository (Update Site in eclipse terms).

Carbon Component: Development Process
Develop the Carbon component
Back-end component (BE OSGi bundles)
Front-end component (FE OSGi bundles)
Common bundles, if any
Develop the corresponding feature
BE/Server Feature
FE/UI Feature
Composite Feature
Install into a Carbon based product
By integrating with the product build system
By developing a feature repository and installing using Feature Manager

Carbon Component: Build Process
We use Maven as our build tool.
Building Carbon components/OSGi bundles
Use Maven Bundle plugin to build OSGi bundles
http://svn.wso2.org/repos/wso2/branches/carbon/3.0.0/components/logging/org.wso2.carbon.logging.service/3.0.0/pom.xml
Building Features
Use Maven P2 Feature plugin (Developed at WSO2)
User p2-feature-gen goal
http://svn.wso2.org/repos/wso2/branches/carbon/3.0.0/features/logging-mgt/org.wso2.carbon.logging.mgt.server.feature/3.0.0/pom.xml
Building a Repository
Use Maven P2 plugin
P2-repo-generator goal
http://svn.wso2.org/repos/wso2/branches/carbon/3.0.0/features/repository/pom.xml

What do you need to know to develop a Carbon component?
Java – to write some code
Carbon - Understand the architecture and the usage
Apache Axis2 - enough to create a service and consume it
JSP
XML
SVN - To check out the code
Maven - To build the code
Plus a little OSGi and a little p2
OSGI is useful for:
Getting OSGi services (e.g. Registry) injected into your code
Handling activation of bundles

Let’s write some code!
Enough talking!

Student Manager Component
Lets develop a sample Carbon component to understand the development process as well as the build process.
Student Manager component
consists of a BE runtime which exposes a Web services to
Add new students
Get the list of students
Consist of a FE console which displays the available student information on the Carbon management console.
Student Manager Feature
org.wso2.carbon.student.mgt.server.feature
org.wso2.carbon.student.mgt.ui.feature
org.wso2.carbon.student.mgt.feature

Developing the BE Component
Some actual server logic plus an admin service to manage it
Add some special sauce into the services.xml to let us know it’s an admin service
component.xml -> configures permissions

BE Component: Directory Structure
org.wso2.carbon.student.mgt
- src/
- main/
- java/
- org/wso2/carbon/student/mgt
- Resources/
- META-INF/
- services.xml
- component.xml
-test/
- pom.xml

Developing the FE Component
Admin service client – standard Axis2 WSDL client
JSP
Helper code sets correct security
component.xml
Defines the menu structure to place the JSP in the right place

FE Component: Directory Structure
org.wso2.carbon.student.mgt.ui
- src/
- main/
- java/
- resources/
studentmgt.wsdl
org/wso2/carbon/student/mgt/ui/i18n/Resources.properties
META-INF/
- component.xml
web/
student-mgt/ (web context of the FE console)
doc/
userguide.html
images/
js/
*.jsp files
pom.xml
