Dropwizard-JAXWS

Dropwizard-JAXWS is a Dropwizard Bundle that enables building SOAP web services and clients using JAX-WS API with Dropwizard.

Features

• Uses Apache CXF web services framework (no Spring Framework dependency).
• Java First and WSDL first service development.
• Using standard JAX-WS annotations, without custom deployment descriptors.
• Metrics instrumentation: @Metered, @Timed and @ExceptionMetered annotations.
• Dropwizard validation support.
• Dropwizard Hibernate support (@UnitOfWork).
• Dropwizard basic authentication using Dropwizard Authenticator.
• Web service client factory.
• Support for JAX-WS handlers, MTOM, CXF interceptors(both client and server side) and CXF @UseAsyncMethod annotation.

Using

To use dropwizard-jaxws in your project, add the following dependency to your pom.xml:

    <dependency>
        <groupId>com.github.roskart.dropwizard-jaxws</groupId>
        <artifactId>dropwizard-jaxws</artifactId>
        <version>1.0.1</version>
    </dependency>

Hello World

SOAP service:

    @Metered
    @WebService
    public HelloWorldSOAP {
        @WebMethod
        public String sayHello() {
            return "Hello world!";
        }
    }

Dropwizard application:

    public class MyApplication extends Application<MyApplicationConfiguration> {

        private JAXWSBundle jaxWsBundle = new JAXWSBundle();

        @Override
        public void initialize(Bootstrap<MyApplicationConfiguration> bootstrap) {
            bootstrap.addBundle(jaxWsBundle);
        }

        @Override
        public void run(MyApplicationConfiguration configuration, Environment environment) throws Exception {
            jaxWsBundle.publishEndpoint(
                new EndpointBuilder("/hello", new HelloWorldSOAP()));
        }

        public static void main(String[] args) throws Exception {
            new MyApplication().run(args);
        }
    }

Client

Using HelloWorldSOAP web service client:

    HelloWorldSOAP helloWorld = jaxWsBundle.getClient(
        new ClientBuilder(HelloWorldSOAP.class, "http://server/path"));
    System.out.println(helloWorld.sayHello());

Examples

Module dropwizard-jaxws-example contains Dropwizard application (JaxWsExampleApplication) with the following SOAP web services and RESTful resources:

• SimpleService: A minimal 'hello world' example.

• JavaFirstService: Java first development example. JavaFirstService interface uses JAX-WS annotations. JavaFirstServiceImpl contains service implementation instrumented with Metrics annotations. Service is secured with basic authentication using dropwizard-auth. BasicAuthenticator implements Dropwizard Authenticator. JavaFirstServiceImpl accesses authenticated user properties via injected JAX-WS WebServiceContext.

• WsdlFirstService: WSDL first development example. WSDL is stored in resources/META-INF/WsdlFirstService.wsdl. Code is generated using cxf-codegen-plugin which is configured in pom.xml. WsdlFirstServiceImpl contains service implementation with blocking and non-blocking methods. WsdlFirstServiceHandler contains server-side JAX-WS handler.

• HibernateExampleService: dropwizard-hibernate example. HibernateExampleService implements the service. @UnitOfWork annotations are used for defining transactional boundaries. @Valid annotation is used for parameter validation on createPerson method. HibernateExampleService accesses the database through PersonDAO. Embedded H2 database is used. Database configuration is stored in Dropwizard config file config.yaml.

• MtomService: WSDL first MTOM attachment example. WSDL is stored in resources/META-INF/MtomService.wsdl. Code is generated using cxf-codegen-plugin which is configured in pom.xml. MtomServiceImpl contains service implementation with MTOM enabled.

• AccessProtectedServiceResource: Dropwizard RESTful service which uses JavaFirstService client to invoke JavaFirstService SOAP web service on the same host. User credentials are provided to access protected service.

• AccessWsdlFirstServiceResource: Dropwizard RESTful service which uses WsdlFirstService client to invoke WsdlFirstService SOAP web service on the same host. WsdlFirstClientHandler contains client-side JAX-WS handler.

• AccessMtomServiceResource: Dropwizard RESTful service which uses MtomService client to invoke MtomService SOAP web service on the same host as an example for client side MTOM support.

• See JaxWsExampleApplication for examples on usage of client side JAX-WS handler and CXF interceptors.

Running the examples:

After cloning the repository, go to the dropwizard-jaxws root folder and run:

    mvn package

To run the example service:

    java -jar dropwizard-jaxws-example\target\dropwizard-jaxws-example-1.0.1.jar server dropwizard-jaxws-example\config.yaml

Notes

Building FAT jar

When using maven-shade-plugin for building fat jar, you must add the following transformer element to plugin configuration:

    <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
        <resource>META-INF/cxf/bus-extensions.txt</resource>
    </transformer>

For example on building fat jar, see dropwizard-jaxws-example/pom.xml.

When using Gradle and a recent version of shadowJar use the following snippet:

shadowJar {
    // ...
    append('META-INF/cxf/bus-extensions.txt')
}
