This example will lead you through creating your first service with doing "code first" development with JAX-WS. You'll learn how to:

• Set up your build for CXF
• Writing a simple JAX-WS service
• Publish your service using the JAX-WS APIs

This example corresponds to the hello_world_code_first example in the CXF distribution. IMPORTANT: This sample is only in CXF 2.0.1+!

Setting up your build

Open up your favorite IDE and create a new project. The first thing we need to do is add the necessary CXF dependencies to the project. You can find these dependencies in the CXF distribution in the lib directory.

commons-logging-1.1.jar
geronimo-activation_1.1_spec-1.0-M1.jar (or Sun's Activation jar)
geronimo-annotation_1.0_spec-1.1.jar (JSR 250)
geronimo-javamail_1.4_spec-1.0-M1.jar (or Sun's JavaMail jar)
geronimo-servlet_2.5_spec-1.1-M1.jar (or Sun's Servlet jar)
geronimo-ws-metadata_2.0_spec-1.1.1.jar (JSR 181)
jaxb-api-2.0.jar
jaxb-impl-2.0.5.jar
jaxws-api-2.0.jar
neethi-2.0.jar
saaj-api-1.3.jar
saaj-impl-1.3.jar
stax-api-1.0.1.jar
wsdl4j-1.6.1.jar
wstx-asl-3.2.1.jar
XmlSchema-1.2.jar
xml-resolver-1.2.jar

The Spring jars (optional - for XML Configuration support):

aopalliance-1.0.jar
spring-core-2.0.4.jar
spring-beans-2.0.4.jar
spring-context-2.0.4.jar
spring-web-2.0.4.jar

And the CXF jar:

cxf-2.0-incubator.jar

Writing your Service

First we'll write our service interface. It will have one operation called "sayHello" which says "Hello" to whoever submits their name.

Our implementation will then look like this:

The @WebService annotation on the implementation class lets CXF know which interface we want to create our WSDL with. In this case its simply our HelloWorld interface.

Publishing your service
