Handler Demo
============

This demo shows how WS-Addressing support in Celtix may be enabled.  

The client and server both use handler configuration to install the
WS-Addressing handlers, comprising a LogicalHandler (MAPAggregator)
responsible for aggregating the WS-A MessageAddressingProperties for
the current message, and a ProtocolHandler (MAPCodec) responsible for
encoding/decoding these properties as SOAP Headers. 

An additional demo-specific ProtocolHandler (HeaderSnoop) is used to
snoop the SOAP Headers and display these to the console.

As you may have seen in other Celtix samples, there are various ways
of installing handlers in an application. The approach used by this
sample is to customize the code generation with a bindings XML fragment
containing the handler definitions. Note that any other approach,
whether programmatic or driven via configuration, would be equally
valid.

Normally the WS-Addressing MessageAddressProperties are generated and
propagated implicitly, without any intravention from the
application. In certain circumstances however, the application may wish
to participate in MAP assembly, for example to associate a sequence of
requests via the RelatesTo header. This demo illustrates both implicit
and explicit MAP propagation.

In all other respects this demo is based on the basic hello_world sample,
illustrating that WS-Addressing usage is independent of the application.
One notable addition to the familiar hello_world WSDL is the usage
of the <wsaw:UsingAddressing> extension element to indicate the
WS-Addressing support is enabled for the service endpoint.

Please review the README in the samples directory before continuing.


Prerequisite
------------

If your environment already includes celtix.jar on the CLASSPATH,
and the JDK and ant bin directories on the PATH, it is not necessary to
run the environment script described in the samples directory README.
If your environment is not properly configured, or if you are planning
on using wsdl2java, javac, and java to build and run the demos, you must
set the environment by running the script.


Building and running the demo using ant
---------------------------------------

From the samples/ws_addressing directory, the ant build script can be used to
build and run the demo.  The server and client targets automatically build
the demo.

Using either UNIX or Windows:

  ant server  (in the background or another window)
  ant client

Both client and server will use the MAPAggregator and MAPCodec
handlers to aggregate and encode the WS-Addressing MAPs.

To remove the code generated from the WSDL file and the .class
files, run:

  ant clean


Buildng the demo using wsdl2java and javac
------------------------------------------

From the samples/ws_addressing directory, first create the target directory
build/classes and then generate code from the WSDL file.

For UNIX:
  mkdir -p build/classes

  wsdl2java -d build/classes ./wsdl/hello_world_addr.wsdl

For Windows:
  mkdir build\classes
    Must use back slashes.

  wsdl2java -d build\classes .\wsdl\hello_world_addr.wsdl

    May use either forward or back slashes.

Now compile both the generated code and the provided client and
server applications with the commands:

  javac -d build/classes src/demo/ws_addressing/common/*.java
  javac -d build/classes src/demo/ws_addressing/client/*.java
  javac -d build/classes src/demo/ws_addressing/server/*.java

Windows may use either forward or back slashes.


Running the demo using java
---------------------------

From the samples/ws_addressing directory run the commands (entered on a single command line):

For UNIX (must use forward slashes):
    java -Djava.util.logging.config.file=$CELTIX_HOME/etc/logging.properties
         demo.ws_addressing.server.Server &

    java -Djava.util.logging.config.file=$CELTIX_HOME/etc/logging.properties
         demo.ws_addressing.client.Client ./wsdl/hello_world_addr.wsdl

The server process starts in the background.

For Windows (may use either forward or back slashes):
  start 
    java -Djava.util.logging.config.file=%CELTIX_HOME%\etc\logging.properties
         demo.ws_addressing.server.Server

    java -Djava.util.logging.config.file=%CELTIX_HOME%\etc\logging.properties
         demo.ws_addressing.client.Client .\wsdl\hello_world_addr.wsdl

The server process starts in a new command window.

After running the client, terminate the server process.

To remove the code generated from the WSDL file and the .class
files, either delete the build directory and its contents or run:

  ant clean
