Holder Pattern Service Sample
|
|
======================================
|
|
This sample demonstrates an SCA service that uses a web service binding. The
|
|
web service binding has been generated from a given WSDL file:
|
|
src/main/resources/wsdl/orderservice.wsdl
|
|
The generated binding has been placed in src/main/java/org/examle/orderservice
|
|
and was generated via the JDK tool wsimport and the command:
|
|
wsimport -d orderservice -keep orderservice.wsdl
|
|
|
|
The interesting feature of this sample is that the generated service interface,
|
|
OrderService, contains a method with the signature:
|
|
public void reviewOrder(
|
|
@WebParam(name = "myData", targetNamespace = "", mode = WebParam.Mode.INOUT)
|
|
javax.xml.ws.Holder<Order> orderData);
|
|
The orderData parameter is an input/output parameter that is provided by the caller,
|
|
updated by the service, and returned to the caller. The business object is updated
|
|
in place, a common pattern in web services, and not returned as a response. Tuscany
|
|
can handle limited instances of this pattern.
|
|
|
|
The README in the samples directory (the directory above this) provides
|
|
general instructions about building and running samples. Take a look there
|
|
first.
|
|
|
|
If you just want to run it to see what happens open a command prompt, navigate
|
|
to this sample directory and do:
|
|
|
|
ant run
|
|
|
|
OR if you don't have ant, on Windows do
|
|
|
|
java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-holder-ws-service.jar org.example.orderservice.OrderServiceTestCase
|
|
|
|
and on *nix do
|
|
|
|
java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-holder-ws-service.jar org.example.orderservice.OrderServiceTestCase
|
|
|
|
Sample Overview
|
|
---------------
|
|
The sample provides a single component that is wired to a service with a
|
|
web service binding.

|
|
Building And Running The Sample Using Ant
|
|
-----------------------------------------
|
|
With the binary distribution the sample can be built and run using Ant using the
|
|
following commands
|
|
|
|
cd holder-ws-service
|
|
ant compile
|
|
ant run
|
|
|
|
You should see the following output from the run target.
|
|
|
|
run:
|
|
[java] 14-Jan-2008 14:18:47 org.apache.tuscany.sca.http.jetty.JettyServer a
|
|
ddServletMapping
|
|
[java] INFO: Added Servlet mapping: http://L3AW203:8085/HelloWorldService
|
|
[java] HelloWorld server started (press enter to shutdown)
|
|
|
|
As this point the SCA service is exposed as a web service by a web server
|
|
started automatically by the SCA runtime. To stop the server just press
|
|
enter.
|
|
|
|
To exercise the service run up the helloworld-ws-reference sample. Take a look at
|
|
the README in that sample and you will see you need the following commands
|
|
|
|
cd holder-ws-reference
|
|
ant run
|
|
|
|
Building And Running The Sample Using Maven
|
|
-------------------------------------------
|
|
With either the binary or source distributions the sample can be built and run
|
|
using Maven as follows. When using Maven you don't need to run the helloworld-
|
|
ws-reference sample as Maven includes a simple ping test to make sure that the
|
|
service is available
|
|
|
|
cd holder-ws-service
|
|
mvn
|
|
|
|
You should see the following output from the test phase.

Note the console output with ">>>" prefix. This shows that an order was submitted in

the "Created" state, handled by the OrderService reviewOrder method, and returned in

the "Approved" state. This shows that the Junit test cases have run successfully.
