Java/Web Services SOA/RPC

The RPC-Literal style binding

 
Hello World Demo using RPC-Literal Style
========================================
This version of Helloe World demonstrates the use
of the RPC-Literal style binding.
Please review the README in the samples directory before
continuing.

Prerequisites
-------------
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/hello_world_RPCLit 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_RPCLit 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_RPCLit.wsdl
For Windows:
  mkdir build\classes
    Must use back slashes.
  wsdl2java -d build\classes -compile .\wsdl\hello_world_RPCLit.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/hwRPCLit/client/*.java
  javac -d build/classes src/demo/hwRPCLit/server/*.java
For Windows:
  set classpath=%classpath%;%CXF_HOME%\lib\cxf-manifest-incubator.jar;.\build\classes
  javac -d build\classes src\demo\hwRPCLit\client\*.java
  javac -d build\classes src\demo\hwRPCLit\server\*.java

Running the demo using java
---------------------------
From the samples/hello_world_RPCLit directory run the following 
commands. They are entered on a single command line:
For UNIX (must use forward slashes):
    java -Djava.util.logging.config.file=$CXF_HOME/etc/logging.properties
         demo.hwRPCLit.server.Server &
    java -Djava.util.logging.config.file=$CXF_HOME/etc/logging.properties
         demo.hwRPCLit.client.Client ./wsdl/hello_world_RPCLit.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.hwRPCLit.server.Server
    java -Djava.util.logging.config.file=%CXF_HOME%\etc\logging.properties
       demo.hwRPCLit.client.Client .\wsdl\hello_world_RPCLit.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_RPCLit 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.hwRPCLit.client.Client http://localhost:#/helloworld/services/hello_world_rpclit?wsdl
  For Windows:
    java -Djava.util.logging.config.file=%CXF_HOME%\etc\logging.properties
       demo.hwRPCLit.client.Client http://localhost:#/helloworld/services/hello_world_rpclit?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.
