Creating a CXF Maven Web Service Client in Eclpise

This post will describe its how easy to create web service client using cxf.

create simple maven project 

• open eclipse 
• create maven project  quick start

WSDL 

I will using weather service to do the deployment. get the wsdl from
http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL

save it at src/main/wsdl/weather.wsdl

add cxf plugin

open the pom.xml

create a tag  <build></build> inside <project> tag if not existing.
create a <plugins></plugins> inside <build> tag
paste following within <plugins> tags

            <plugin>
                <groupId>org.apache.cxf</groupId>
                <artifactId>cxf-codegen-plugin</artifactId>
                <version>2.1.2</version>
                <executions>
                    <execution>
                        <id>generate-sources</id>
                        <phase>generate-sources</phase>
                        <configuration>
                            <sourceRoot>target/generated/cxf</sourceRoot>
                            <wsdlOptions>
                                <wsdlOption>
                                    <wsdl>src/main/wsdl/weather.wsdl</wsdl>
                                </wsdlOption>
                            </wsdlOptions>
                        </configuration>
                        <goals>
                            <goal>wsdl2java</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

implementation

generate-sources
use following command to generate the java classes from wsdl.

mvn generate-sources

create a jar file using
mv install
 
java codes should be created at target folder.
new java files should be able to located at
target/generated/cxf

to use the code in our code, for eclipse we will have to add the newly created jar to class path.

now go to main java class.

and update it to call the web service.

    public static void main( String[] args )
    {
        System.out.println( "Hello World!" );
        Weather weather = new Weather();
        WeatherSoap weatherSoap = weather.getWeatherSoap();
        ForecastReturn forecastReturn=weatherSoap.getCityForecastByZIP("94025");
       
        List< Forecast > forecasts = forecastReturn.getForecastResult().getForecast();
       
        for (Forecast forecast : forecasts ){
            System.out.println("------------------------------");
            System.out.println(forecast.getDate().toString());
            System.out.println(forecast.getProbabilityOfPrecipiation().getDaytime().toString() );
            System.out.println(forecast.getTemperatures().getDaytimeHigh().toString());
            System.out.println(forecast.getDesciption().toString());
            System.out.println(forecast.getWeatherID() );
            System.out.println(forecast.getClass().toString());
          
          
        }
    }

out put will  be

Hello World!

NOTE:
eclipse validation will requests to put plugins tag inside plugins management in the pom.xml. Even though this will solve eclipse issue, it will not create the java files using wsdl. so make sure plugins tag is directly under build tag.
