Hello World Secure Web Service Service Sample
=============================================
This sample demonstrates an SCA service that uses a web service binding that is enabled for simple
authentication using UseridToken and PasswordText

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-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

Now the server is started you can use the helloworld-ws-reference-secure sample to 
exercise it. 

Sample Overview
---------------
The sample provides a single component that is wired to a service with a 
web service binding.  The service specifies a policy intent named 'authentication' 
which is fulfilled by a suitable policyset that is defined for the SCA Domain.  Over 
the helloworld-ws-service 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.

          									for user identifiers sent by the client and verifying them 
          									against the password sent by the client.  For example
          									here is where one could access LDAP registries to obtain or
          									compare user identities and passwords.

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 helloworld-ws-service-secure
ant compile
ant run

You should see the following output from the run target.

run:
     [java] 14-Jan-2008 14:22:07 org.apache.tuscany.sca.http.jetty.JettyServer a
ddServletMapping
     [java] INFO: Added Servlet mapping: http://L3AW203:8085/HelloWorldService
     [java] 14-Jan-2008 14:22:07 org.apache.tuscany.sca.http.jetty.JettyServer a

     [java] INFO: Added Servlet mapping: http://L3AW203:8085/HelloWorldWsPolicyS
ervice
     [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. The webservice requires clients to 
have security headers that carry userid tonken and password text.

To stop the server just press enter.

To exercise the service run up the helloworld-ws-reference-secure sample. Take a look at 
the README in that sample and you will see you need the following commands

cd helloworld-ws-reference-secure
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-secure sample as Maven includes a simple ping test to make sure that the
service is available

cd helloworld-ws-service-secure
mvn

You should see the following output from the test phase.
