The RPC-Literal style binding

   <source lang="java">

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.
