JAX-WS based Webservice application

Step1: using eclipse ide developed Jax-ws webservice application

                                                                                                    

File>new>dyanmicwebproject>Enter project name >next>next>finish

create new class (showing below screen shot)

create class as SumService

Then right click on java class >webservice>create webservice

then open below window

after drag the test service and test client(show in bleow image)

>next>next> then get this

after next>next>---->finish  after open below browser here you enter input values then press invoke button get the result(for testing only)

now see the your package structure

Client Application:

create java project>after create java project

then open

after click the browse button

choose browse button  select our wsdl document

>ok

>next>next>next>finish

Now see your packages there new class

now create your own class

create new class as client

create object sumserviceproxy class using this instance we can cal our webservice method shown below

Struts2 with Rest Application

* In Struts2 Rest application must contains some naming conventions

struts.xml:
----------
<struts>
<constant name="struts.convention.action.suffix" value="Controller">/
<constant name="struts.convention.action.mapAllMatches" value="true"/>
<constant name="struts.convention.default.parent.package" value="rest-default"/>
<constant name="struts.convention.package.locators" value="example"/>
</struts>


* Ur class name  must start with action  name with suffix as Controller (e.g suppose ur action name is orders ur class name must be OrdersController).

*Another role is ur controller class must be contains in the "example" package.(it means which package are mentioned in the constant (e.g <constant name="struts.convention.package.locators" value="example">).
