Hello World Secure Web Service References Sample
|
|
================================================
|
|
This sample demonstrates an SCA reference that uses a web service binding.
|
|
|
|
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 you need to run the server first
|
|
so open a command prompt, navigate to the helloworld-ws-service 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-helloworld-ws-service-secure.jar helloworld.HelloWorldServer
|
|
|
|
and on *nix do
|
|
|
|
java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-helloworld-ws-service-secure.jar helloworld.HelloWorldServer
|
|
|
|
|
|
Once the server is running 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-helloworld-ws-reference-secure.jar helloworld.HelloWorldClient
|
|
|
|
and on *nix do
|
|
|
|
java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-helloworld-ws-reference-secure.jar helloworld.HelloWorldClient
|
|
|
|
|
|
Sample Overview
|
|
---------------
|
|
The sample provides a single component that is wired to a reference with a
|
|
web service binding. The binding refers to WSDL that identifies the service
|
|
exposed by the helloworld-ws-service-secure sample. This sample invokes a
|
|
secure web-serivce and hence specifies a policy intent named 'authentication'
|
|
which is fulfilled by a suitable policyset that is defined for the SCA Domain.
|
|
Over the helloworld-ws-reference sample, this sample demonstrate generally
|
|
the use of policy intents and policy sets in Tuscany taking the specific instance
|
|
of a security policy.
|
|
|
|
Note :
|
|
------
|
|
The policies mentioned and supported are instances of Tuscany specified policies and
|
|
not instnaces of WS-Policy.

Building And Running The Sample Using Ant
|
|
-----------------------------------------
|
|
With the binary distribution the sample can be built and run using Ant. Before
|
|
you do this start up the service that the reference will talk to. To do this
|
|
run up the helloworld-ws-service-secure test. Take a look at the README in that sample
|
|
and you will see you need the following commands
|
|
|
|
cd helloworld-ws-service-secure
|
|
ant run
|
|
|
|
Once done you can now compile and run this sample using the following commands;
|
|
|
|
cd helloworld-ws-reference-secure
|
|
ant compile
|
|
ant run
|
|
|
|
You should see the following output from the run target.
|
|
|
|
run:
|
|
[java] log4j:WARN No appenders could be found for logger (org.apache.axiom.
|
|
om.util.StAXUtils).
|
|
[java] log4j:WARN Please initialize the log4j system properly.
|
|

|
|
[java] Called getGreetings
|
|
[java] *** Calling Client UserId/Password Handler ....
|
|
[java] Hello World
|
|
|
|
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-service-secure sample first as Maven does this for you.
|
|
|
|
cd helloworld-ws-reference-secure
|
|
mvn
|
|
|
|
You should see the following output from the test phase.
