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

This demo shows how to use JAX-WS handlers. The server uses a SOAP protocol 
handler to log incoming and outgoing messages to the console. 

The server code registers a handler using the @HandlerChain annotation within 
the service implementation class. For this demo, LoggingHandler is a SOAPHandler 
that logs the entire SOAP message content to stdout.

The client includes a logical handler that checks the parameters on outbound 
requests and short-circuits the invocation in certain circumstances. This 
handler is specified programmatically.

Please review the README in the samples directory before continuing.


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

$SUBSTITUTE_PREREQ$


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

From the samples/handlers directory, use the following commands to build and run 
the demo on either UNIX or Windows:

  ant build
  ant server 
  ant client

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

  ant clean


The server process uses the LoggingHandler and the client process uses the 
SmallNumberHandler. Notice that both the client and server consoles display 
short informative messages. The client handler examines the operation parameters 
and, based on the parameter values, may decide not to forward the request to the 
server. The server handler displays the entire content of each message in its 
console. The @HandlerChain annotation in the implementation class indicates that 
the file demo_handler.xml includes the information needed to identify the 
handler class.

  @HandlerChain(file = "../common/demo_handlers.xml", name = "DemoHandlerChain")

The client side SmallNumberHandler is specified programmatically:

    SmallNumberHandler sh = new SmallNumberHandler();
    List<Handler> newHandlerChain = new ArrayList<Handler>();
    newHandlerChain.add(sh);
    ((BindingProvider)port).getBinding().setHandlerChain(newHandlerChain);

After running the client, terminate the server process.


Building the demo using wsdl2java and javac
-------------------------------------------

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

For UNIX:

  mkdir -p build/classes

  $THE_TOOL$ wsdl2java -d build/classes -compile ./wsdl/addNumbers.wsdl

For Windows:

  mkdir build\classes
    (You must use backslashes.)

  $THE_TOOL$ wsdl2java -d build\classes -compile .\wsdl\addNumbers.wsdl

    (Use either forward or backslashes.)

Now compile the provided client and server applications with the commands:

For UNIX:  
  
  export CLASSPATH=$CLASSPATH:./build/classes
  javac -d build/classes src/demo/handlers/common/*.java
  javac -d build/classes src/demo/handlers/client/*.java
  javac -d build/classes src/demo/handlers/server/*.java

For Windows:

  set classpath=%classpath%;.\build\classes
  javac -d build\classes src\demo\handlers\common\*.java
  javac -d build\classes src\demo\handlers\client\*.java
  javac -d build\classes src\demo\handlers\server\*.java

Finally, copy the demo_handlers.xml file from the src/demo/handlers/common
directory into the build/classes/demo/handlers/common directory.

For UNIX:

  cp ./src/demo/handlers/common/demo_handlers.xml ./build/classes/demo/handlers/common

For Windows:

  copy src\demo\handlers\common\demo_handlers.xml build\classes\demo\handlers\common



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

From the samples/handlers directory run the following commands on a single command line:

For UNIX (you must use forward slashes):

    java -Djava.util.logging.config.file=$$SUBSTITUTE_HOME$/etc/logging.properties
         demo.handlers.server.Server &

    java -Djava.util.logging.config.file=$$SUBSTITUTE_HOME$/etc/logging.properties
         demo.handlers.client.Client ./wsdl/addNumbers.wsdl

The server process starts in the background.

For Windows (use either forward or backslashes):

  start 
    java -Djava.util.logging.config.file=%$SUBSTITUTE_HOME$%\etc\logging.properties
         demo.handlers.server.Server

    java -Djava.util.logging.config.file=%$SUBSTITUTE_HOME$%\etc\logging.properties
         demo.handlers.client.Client .\wsdl\addNumbers.wsdl

The server process starts in a new command window.

After running the client, terminate the server process by issuing Ctrl-C in its 
command window.
