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, CXF interceptors(both client and server side) and MTOM.

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>0.8.0</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. 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-0.8.0.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')
}
