Apache WS Evolution<\/h2><\/span>\n

First generation: Apache SOAP
\nSecond generation: Axis
\nThird generation: Axis2<\/p>\n

Axis2 Architecture<\/h2><\/span>\n

Core Modules<\/h3><\/span>\n

XML Processing Module<\/h4><\/span>\n

*AXIOM (Axis Object Model)
\n– Based on PULL parser so more control over XML parsing<\/p>\n

SOAP Processing Module<\/h4><\/span>\n

* Handlers: intercept and process part of SOAP message
\n– Three scopes: global, service, operation scope
\n* Phases: logical collection of one or more handlers
\n– They’re handler containers
\n– They also order handlers
\n* Pipers
\n– InFlow
\n~ Last handler is Message Receiver
\n– OutFlow<\/p>\n

Information Processing Module<\/h4><\/span>\n

* Description hierarchy: comes from deployment descriptors
\nConfiguration<>-ServiceGroup<>-Service<>-Operation<>-Message
\n* Context hierarchy: keeps run-time data
\nConfigurationContext<>-ServiceGroupContext<>-ServiceContext<>-OperationContext<>-MessageContext<\/p>\n

Deployment Module<\/h4><\/span>\n

* Axis2 supports:
\n– Hot deployment
\n– Hot update
\n* Service extension by modules
\nA module contains:
\n– Handlers
\n– Third party libraries
\n– Module related resources
\n– Moduel config file (module.xml)
\nA module can be deployed as a .mar file
\n* Axis2 can be deployed as
\n– Archive file: a .aar file
\n– POJO deployment
\n– Custom deployer<\/p>\n

Client API Module<\/h4><\/span>\n

* ServiceClient API: used to access SOAP body (payload)
\nsendRobust(): one way but traps exception
\nfireAndForget(): one way and don’t care exception
\nsendReceive(): sunc two way
\nsendReceiveNonBlocking(): async two way<\/p>\n

* OperationClient API: used to modify SOAP header
\nCreate ServiceClient -> Create OperationClient -> Create SOAPEnvelope -> Create MessageContext -> Add SOAPEnvelope to MessageContext -> Add MessageContext to OperationClient -> Invoke OperationClient – (if response) -> Get response MessageContext form OperationClient<\/p>\n

Transport Module<\/h4><\/span>\n

Supports:
\n* HTTP\/HTTPS
\n* TCP: needs WS-Addressing
\n* SMTP
\n* JMS
\n* XMPP<\/p>\n

Non Core Modules<\/h3><\/span>\n

Code Generation Module<\/h4><\/span>\n

Data Binding Module<\/h4><\/span>\n

Supports
\n* ADB (Axiss Data Binding)
\n* XMLBeans
\n* JaxMe: included in XMLBeans
\n* JibX
\n
