WS-Policy Demo
==
This demo shows how the CXF WS-Policy framework in Apache CXF uses WSDL 1.1 Policy attachments to enable the use of WS-Addressing. While most of the demo is very similar to the ws_addressing demo, there are two major differences: 1. � Policy element containing an Addressing assertion is attached to the port element in the demo"s wsdl. 2. The configuration files for the client and server specify that the CXF policy engine should be enabled. In addition, the configuration file for the server tells the policy engine where to look for external policy attachments. This is necessary since neither the implementor not the interface specify wsdlLocation in their WebService annotation (the client could also use external policy attachments instead of WSDL 1.1 attachments). Note that, apart from the configuration of the decoupled http endpoint on which the client receives responses from the server, nothing else needs to be configured. In particular, there is no need to specify the WS-Addressing interceptors. The internals of what is involved in ensuring that addressing headers are added to the messages (namely: the addition of two addressing interceptors to the inbound and outbound fault and message processing chains) are left to the policy framework, or rather: its built-in support for the Addressing assertion. 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 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_policy 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 ant client
Although not explicitly instructed to use these interceptors, both client and server will use the MAPAggregator and MAPCodec interceptors 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_policy 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_addr.wsdl
For Windows:
mkdir build\classes Must use back slashes. wsdl2java -d build\classes -compile .\wsdl\hello_world_addr.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/ws_policy/common/*.java javac -d build/classes src/demo/ws_policy/client/*.java javac -d build/classes src/demo/ws_policy/server/*.java
For Windows:
set classpath=%classpath%;%CXF_HOME%\lib\cxf-manifest-incubator.jar;.\build\classes;. javac -d build\classes src\demo\ws_policy\common\*.java javac -d build\classes src\demo\ws_policy\client\*.java javac -d build\classes src\demo\ws_policy\server\*.java
Running the demo using java
From the samples/ws_policy directory run the commands (entered on a single command line): For UNIX (must use forward slashes):
java -Djava.util.logging.config.file=./logging.properties
-Dcxf.config.file=server.xml
demo.ws_policy.server.Server &
java -Djava.util.logging.config.file=./logging.properties
-Dcxf.config.file=client.xml
demo.ws_policy.client.Client
The server process starts in the background. For Windows (may use either forward or back slashes):
start
java -Djava.util.logging.config.file=.\logging.properties
-Dcxf.config.file=server.xml
demo.ws_policy.server.Server
java -Djava.util.logging.config.file=.\logging.properties
-Dcxf.config.file=client.xml
demo.ws_policy.client.Client
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
