When using a contract-last approach, you start with the Java code, and let the Web service contract (WSDL, see sidebar) be generated from that.

When using contract-first, you start with the WSDL contract, and use Java to implement said contract.

), celle-ci est en effet la plus simple mettre en uvre.

Le principe est de crer le service sous forme de classes ( et d'interfaces ) java, et d'utiliser un outil (gnralement inclus dans l'API utilis) qui permet de gnrer automatiquement le WDSL correspondant.

We will also take advantage of the latest Spring WS 2.0.0 RC2 features.

We will also use marshalling techniques to efficiently manipulate XML requests.

This will also be our basis for the next tutorial: Spring WS and Spring MVC Integration. Spring Web Services (Spring-WS) is a product of the Spring community focused on creating document-driven Web services.

Spring Web Services aims to facilitate contract-first SOAP service development, allowing for the creation of flexible web services using one of the many ways to manipulate XML payloads.

Mais quels sont donc les avantages de Spring WS par rapport ces autres framework ?Cette tape peut prendre diffrentes formes : gnration manuelle du WSDL grce un outil, gnration automatique grce une fabrique Spring, ou encore gnration automatique partir d'annotations Java 5.Cette manire de procder ne ncessite pas spcialement une grande connaissance de SOAP, des WSDL, voir mme de XML.These are developed in a Maven2 build environment with testing through JUnit4 and reporting via PMD and Cobertura.This installment will add a SOAP service but we will put off writing the client until the next article and in its place we will utilize an useful application called Soap UI to test our SOAP service.
