Hello World Demo using Document/Literal Style
=============================================
This demo illustrates how to develop a service use the "code first"
approach using the JAX-WS APIs.
Prerequisite
------------
If your environment already includes cxf-manifest-incubator.jar on the
CLASSPATH, and the JDK and ant bin directories on the PATH
it is not necessary to set the environment as 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.

Building and running the demo using ant
---------------------------------------
From the samples/hello_world directory, the ant build script
can be used to build and run the demo.
Using 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

Building the demo using wsdl2java and javac
-------------------------------------------
From the samples/hello_world 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 -compile ./wsdl/hello_world.wsdl
For Windows:
mkdir build\classes
Must use back slashes.
wsdl2java -d build\classes -compile .\wsdl\hello_world.wsdl
May use either forward or back slashes.
Now compile the provided client and server applications with the commands:
For UNIX:

export CLASSPATH=$CLASSPATH:$CXF_HOME/lib/cxf-manifest-incubator.jar:./build/classes
javac -d build/classes src/demo/hw/client/*.java
javac -d build/classes src/demo/hw/server/*.java
For Windows:
set classpath=%classpath%;%CXF_HOME%\lib\cxf-manifest-incubator.jar;.\build\classes
javac -d build\classes src\demo\hw\client\*.java
javac -d build\classes src\demo\hw\server\*.java

Running the demo using java
---------------------------
From the samples/hello_world directory run the commands, entered on a
single command line:
For UNIX (must use forward slashes):
java -Djava.util.logging.config.file=$CXF_HOME/etc/logging.properties
demo.hw.server.Server &
java -Djava.util.logging.config.file=$CXF_HOME/etc/logging.properties
demo.hw.client.Client ./wsdl/hello_world.wsdl
The server process starts in the background. After running the client,
use the kill command to terminate the server process.
For Windows (may use either forward or back slashes):
start
java -Djava.util.logging.config.file=%CXF_HOME%\etc\logging.properties
demo.hw.server.Server
java -Djava.util.logging.config.file=%CXF_HOME%\etc\logging.properties
demo.hw.client.Client .\wsdl\hello_world.wsdl
A new command windows opens for the server process. After running the
client, terminate the server process by issuing Ctrl-C in its command window.
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

Building and running the demo in a servlet container
----------------------------------------------------
From the samples/hello_world directory, the ant build script
can be used to create the war file that is deployed into the
servlet container.
Build the war file with the command:
ant war

Preparing deploy to APACHE TOMCAT
* set CATALINA_HOME environment to your TOMCAT home directory

Deploy the application into APACHE TOMCAT with the commond:
[NOTE] This step will check if the cxf jars present in Tomcat,
if not, it will automatically copy all the jars into CATALINA_HOME/shared/lib

ant deploy -Dtomcat=true
The servlet container will extract the war and deploy the application.

Using ant, run the client application with the command:
ant client-servlet -Dbase.url=http://localhost:#
Where # is the TCP/IP port used by the servlet container,
e.g., 8080.
Or
ant client-servlet -Dhost=localhost -Dport=8080
You can ignore the -Dhost and -Dport if your tomcat setup is same, i.e ant client-servlet
Using java, run the client application with the command:
For UNIX:

java -Djava.util.logging.config.file=$CXF_HOME/etc/logging.properties
demo.hw.client.Client http://localhost:#/helloworld/services/hello_world?wsdl
For Windows:
java -Djava.util.logging.config.file=%CXF_HOME%\etc\logging.properties
demo.hw.client.Client http://localhost:#/helloworld/services/hello_world?wsdl
Where # is the TCP/IP port used by the servlet container,
e.g., 8080.
Undeploy the application from the APACHE TOMCAT with the command:
ant undeploy -Dtomcat=true

Running demo with HTTP GET
----------------------------------------------------
APACHE CXF support HTTP GET to invoke the service, instead of running
ant client
you can use
ant client.get
to invoke the service with simple HttpURLConnection, or you can even
use your favoriate browser to get the results back.
