Callback Demo
=============================================
This demo shows a client creating a callback object by
passing an EndpointReferenceType to the server. The
EndpointRefrenceType is then used by the server to call
back on the callback object
Please review the README in the samples directory before
continuing.
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's 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/basic_callback 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/basic_callback 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/basic_callback.wsdl
For Windows:
mkdir build\classes
Must use back slashes.
wsdl2java -d build\classes -compile .\wsdl\basic_callback.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/callback/client/*.java
javac -d build/classes src/demo/callback/server/*.java
For Windows:
set classpath=%classpath%;%CXF_HOME%\lib\cxf-manifest-incubator.jar;.\build\classes
javac -d build\classes src\demo\callback\client\*.java
javac -d build\classes src\demo\callback\server\*.java
Running the demo using java
---------------------------
From the samples/basic_callback directory run the commands, entered on a
single command line:
For UNIX (must use forward slashes):
java -Djava.util.logging.config.file=$CXF_HOME/etc/logging.properties
demo.callback.server.Server &
java -Djava.util.logging.config.file=$CXF_HOME/etc/logging.properties
demo.callback.client.Client ./wsdl/basic_callback.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.callback.server.Server
java -Djava.util.logging.config.file=%CXF_HOME%\etc\logging.properties
demo.callback.client.Client .\wsdl\basic_callback.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
