This demo illustrates how to develop a service use the code first approach using the JAX-WS APIs

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=$CXF_HOME/etc/logging.properties demo.hw.client.Client http://localhost:#/helloworld/services/hello_world?wsdl For Windows: java -Djava.util.logging.config.file=%CXF_HOME%\etc\logging.properties demo.hw.client.Client http://localhost:#/helloworld/services/hello_world?wsdl Where # is the TCP/IP port used by the servlet container, e.g., 8080. Undeploy the application from the APACHE TOMCAT with the command: ant undeploy -Dtomcat=true Running demo with HTTP GET ---------------------------------------------------- APACHE CXF support HTTP GET to invoke the service, instead of running ant client you can use ant client.get to invoke the service with simple HttpURLConnection, or you can even use your favoriate browser to get the results back. //////////////////////////////////////////////////////////////////////// <?xml version="1.0" encoding="UTF-8"?>  <project name="hello world code first demo" default="build" basedir="."> <import file="common_build.xml"/> <target name="client" description="run demo client" depends="build"> <property name="param" value=""/> <cxfrun classname="demo.hw.client.Client" param1="" param2="${op}" param3="${param}"/> </target> <target name="server" description="run demo server" depends="build"> <cxfrun classname="demo.hw.server.Server"/> </target> <property name="cxf.war.file.name" value="helloworld"/> <target name="war" depends="build"> <cxfwar wsdl="hello_world.wsdl" filename="${cxf.war.file.name}.war"/> </target> <target name="client-servlet" description="run demo client hitting servlet" depends="build"> <property name="param" value=""/> <cxfrun classname="demo.hw.client.Client" param1="${base.url}/helloworld/services/hello_world?wsdl" param2="${op}" param3="${param}"/> </target> </project> //////////////////////////////////////////////////////////////////////// /** * Licensed to the Apache Software Foundation (ASF) under one * or more contributor license agreements.
