4. Implementing Spring Web Services for SOAP - Maven Archetype

Using a Spring Web Services Archetype

In this section, you will create a boilerplate Spring Web Services project in Eclipse using the Spring Web Services Maven Archetype.

Steps:

1. Project Setup
   • Step 1: Open Eclipse
     • Launch Eclipse IDE on your computer.
   • Step 2: Create a New Maven Project
     • Go to File > New > Project.
     • Select Maven Project from the list and click Next.
   • Step 3: Select Project Location
     • Choose the workspace location for your project or accept the default location and click Next.
   • Step 4: Select an Archetype
     • In the Archetype selection window, click Add Archetype.
     • Enter the following details:
       • Group Id: org.springframework.ws
       • Artifact Id: spring-ws-archetype
       • Version: 2.4.0 (or the latest version available)
     • Click OK, then select the added archetype and click Next.
   • Step 5: Define Project Coordinates
     • Enter the following details:
       • Group Id: com.nicordesigns
       • Artifact Id: spring-ws-charityregistration
       • Version: 1.0-SNAPSHOT
     • Click Finish.
2. Configuration
   • Step 1: Open Spring Configuration File
     • Navigate to src/main/resources and open the Spring configuration file (applicationContext.xml or in our case web.xml and spring-ws-servlet.xml ).
   • Step 2: Enable WSDL Generation
     • Add the necessary configurations to generate the SOAP WSDL file automatically. This typically involves defining beans for DefaultWsdl11Definition and XsdSchema.
3. Service Layer Development
   • Step 1: Create Service Interface
     • In the src/main/java directory, create a new package and a Java Interface for your service. Interface name to align with generated WSDL wsdl:portType
   • Step 2: Implement Service Interface
     • Create an implementation class for the service interface.
4. SOAP Endpoint Implementation
   • Step 1: Define Endpoint Class
     • Create a new class for your SOAP endpoint and annotate it with @Endpoint.
   • Step 2: Map Requests to Methods
     • Use @PayloadRoot, @RequestPayload, and @ResponsePayload annotations to map incoming SOAP requests to appropriate methods.
