Hierarchical service deployment support in WSO2 WSAS-3.2.0

WSO2 WSAS-3.2.0 is the latest version of WSO2 Web Services Application Server which consists of some new features as well as a lot of bug fixes. Hierarchical service deployment is one of the new features included in the latest WSAS.
Hierarchical service deployment model allows you to deploy two (or more) different versions of the same service in a very easy manner.
Lets see how multiple versions of the same services can be deployed on WSAS-3.2.0

Download WSO2 WSAS-3.2.0 from here

Step 1

Start WSO2 WSAS by running wso2server.sh{bat} from WSAS_HOME/bin
Access management console using https://localhost:9443/carbon and log in with the default credentials(admin/admin)

Select Axis2 Service from the left navigation menu.

You will notice there is an input text box, Service Hierarchy. Here you can specify a service path. eg:- /marketing/test
Browse a service archive (eg:- Axis2Service.aar) in your local file system and click on Upload.
The service will be deployed successfully, go to the service list page and you will the service is listed there as follows. The service name is prefixed with the hierarchy path you have given when deploying the service (marketing/test/Axis2Service)

Step 2

Now, we are going to deploy a different version of the same Axis2Service. Access the Manage --> Services --> Add --> Axis2 Service page and specify a new service hierarchy (eg:- /sales/test)
Browse the same service archive which have deployed in the previous step (Axis2Service.aar) and click on upload.

Now, you will notice a different version of the same service, sales/test/Axis2Service listed in the service management page.

Likewise, you can deploy many versions of the same service and make use them in your SOA infrastructure. Hierarchical service deployment facility can be used in Spring, Jax-WS and Jar services as well.
