24. Class Loading Customization
o There are 4 in-built environment.
o Tomcat – Minimal runtime (Tomcat)
o Carbon – Tomcat + Carbon + Axis2
o CXF – Tomcat + CXF + Spring
o JavaEE – Tomcat + TomEE
o Users can add their own Class loading
environments
o Edit {carbon.home}/repository/conf/ tomcat/
webappclassloading-environments.xml file
o

25. Class Loading Customization cont.
o Configure per server or per application
o {carbon.home}/repository/conf/tomcat/webapp-
classloading.xml
o META-INF/webapp-classloading.xml
o Can provide mix of environment (e.g. CXF,
Carbon)
o To specify CXF/Carbon as the runtime
environments users should have the following
configuration <Classloading xmlns="http://wso2.org/projects/as/classloading">
<Environments>CXF,Carbon</Environments>
</Classloading>

26. Lazy Loading and Resource Management
o App servers usually run for a long time
o Keeping inactive applications on memory for a
long time, may affect performance
o App server restarting can cause considerable
amount of app downtime and affect availability
o Resources such as memory, cache and
processor time are expensive, hence need
better resource management
o Lazy loading and resource sharing
mechanisms should not negatively affect end-
user experience

27. Tenant Lazy Loading
o When a request is received, an
interceptor will assess request
details (e.g. URL, session info)
o Based on the request details, the
interceptor will pick the
corresponding Tenant from the
tenant store
o A Task will be running in the
background to identify inactive
tenant(s)
o When a tenant is inactive for a
predefined duration (e.g. 30 min),
the tenant will be un-loaded

30. Caching, Clustering & Session
Replication

31. Clustering and Session Replication
o Capable of storing session specific data in Web
services at 3 levels
o ServiceContext level
o ServiceGroupContext level
o ConfigurationContext level
o Clustering is based on the Hazelcast

32. Deployment Synchronization
o Synchronizing the main
repository of Carbon
server with a set of
nodes
o Usually one READ-
WRITE repository with
number of READ-ONLY
repositories
o SVN based synchronizer
Deployment Synchronizer

(R/W)

33. WSO2 Carbon Features

34. WSO2 Carbon Features with Webapps
o Carbon Webapp runs on Tomcat, while
o Other Webapps deployed in parallel to Carbon Webapp
o API’s are shared across all Webapps to enable important
Carbon features for external Web Apps
o Authentication
o Registry (Metadata Repository)
o Carbon Caching
Registry Repository
Carbon Context
User Store
Registry User Management Caching

35. Carbon Authentication for Webapps
o All Carbon functionalities are implemented as
Web Services, called Carbon Admin Services
o AuthenticationAdmin Service - handles all
Authentication functionalities
o AuthenticationAdminClient API
o Talks to the Admin Service
o Webapps can use it to communicate with the Carbon
User store
o Any User store can be plugged into Carbon
(Default LDAP)

36. Registry for Webapps
o WSO2 Governance Registry is used by all
WSO2 products as a metadata repository
o Webapps also can use it for the same purpose
through the CarbonContextAPI

37. Web Service Deployment
o SOAP 1.1/1.2 and Restful Axis2 web services
o JAX-WS 2.2 web services and JAX-RS
services
o

38. Development with
WSO2 Developer Studio

39. WSO2 Developer Studio
o The development tool for writing applications
that get hosted on one/more of Carbon servers
o Based on the popular Eclipse IDE with all
familiar tools at hand
o Contains diverse set of tools vital for
configuring your enterprise architecture
