TOTD #18: How to Add Metro Quality-of-Service to Contract-First Endpoint ?

This TOTD explains how to add Reliability and Security to a Contract-First
Endpoint using NetBeans IDE.

In the Contract-First, the contract, i.e. the WSDL, is defined first as
opposed to starting from Java. The Metro programming model starts with a Java
Service Endpoint Interface (SEI) and uses
Web
Service Designer to specify Security, Reliability and Transactions support.
This blog uses the WSDL bundled with the fromwsdl sample of
Metro download and adds
Quality-of-Service attributes to it.

Here are the steps to enable Reliable Messaging to Contract-First endpoint:

1. In a new Web project, right-click and select "

   Web Service from 
   	WSDL...

   " as shown below:
   
   
   
   
2. Specify the Web Service Name, package name and chose the location of the
   WSDL as shown below:
   
   
   
   
   
   
   
   The Web Service port name is chosen for you. Alternatively, you can click on
   "Browse..." button next to "Web Service Port:" and
   select the appropriate port.
3. Click on "Finish" and the Web Services Designer is shown as
   shown below:
   
   
   
   
4. Right-click on the Project and select on "Undeploy and Deploy"
   to deploy the project.
5. Expand the "Web Services" tree, select the newly added Web
   service and right-click on "Test Web Service". The Tester page
   is shown in a browser with links to the packaged WSDL file and text boxes
   and buttons to invoke the Web service.
6. In the Web Services Designer, select "Reliable Message Delivery".
7. Right-click on the project, select "Clean" to clean all the
   generated files. Again right-click on the project and then select "

   Undeploy 
   	and Deploy

   " to deploy the project again.
8. As in step 5 above, test the Web service. The packaged WSDL now contains
   the appropriate policy assertions and Reliable Message Delivery is enabled
   on the endpoint.

As described in
screencast
#ws7, Security can be added to a Contract-First endpoint using the steps
listed above.
