14.3.2. Write and Deploy a JAX-WS Web Service Endpoint
This topic discusses the development of a simple JAX-WS service endpoint, which is the server-side component, which responds to requests from JAX-WS clients and publishes the WSDL definition for itself. For more in-depth information about JAX-WS service endpoints, refer to Section 14.5.2, “JAX-WS Common API Reference” and the API documentation bundle in Javadoc format, distributed with JBoss EAP 6.
A Web Service must fulfill the requirements of the JAXWS API and the Web Services meta data specification at http://www.jcp.org/en/jsr/summary?id=181. A valid implementation meets the following requirements:
- It contains a
javax.jws.WebServiceannotation. - All method parameters and return types are compatible with the JAXB 2.0 specification, JSR-222. Refer to http://www.jcp.org/en/jsr/summary?id=222 for more information.
Example 14.13. Example Service Implementation
package org.jboss.test.ws.jaxws.samples.retail.profile;
import javax.ejb.Stateless;
import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.jws.soap.SOAPBinding;
@Stateless
@WebService(
name="ProfileMgmt",
targetNamespace = "http://org.jboss.ws/samples/retail/profile",
serviceName = "ProfileMgmtService")
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
public class ProfileMgmtBean {
@WebMethod
public DiscountResponse getCustomerDiscount(DiscountRequest request) {
return new DiscountResponse(request.getCustomer(), 10.00);
}
}
Example 14.14. Example XML Payload
DiscountRequest class which is used by the ProfileMgmtBean bean in the previous example. The annotations are included for verbosity. Typically, the JAXB defaults are reasonable and do not need to be specified.
package org.jboss.test.ws.jaxws.samples.retail.profile;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlType;
import org.jboss.test.ws.jaxws.samples.retail.Customer;
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType( (1)
name = "discountRequest",
namespace="http://org.jboss.ws/samples/retail/profile",
propOrder = { "customer" }
)
public class DiscountRequest {
protected Customer customer;
public DiscountRequest() {
}
public DiscountRequest(Customer customer) {
this.customer = customer;
}
public Customer getCustomer() {
return customer;
}
public void setCustomer(Customer value) {
this.customer = value;
}
}
The implementation class is wrapped in a JAR deployment. Any metadata required for deployment is taken from the annotations on the implementation class and the service endpoint interface. Deploy the JAR using the Management CLI or the Management Interface, and the HTTP endpoint is created automatically.
Example 14.15. Example JAR Structure for a Web Service Deployment
