Agent Skills: GuicedEE Web Services

GuicedEE Web Services

SOAP web services using Apache CXF conventions inside GuicedEE.

Core Concept

Build SOAP services using standard JAX-WS annotations (@WebService, @WebMethod, @WebParam, @WebResult) and configure endpoints, bindings, interceptors, and WS-Security in the same way you would with CXF. Works alongside GuicedEE Vert.x Web and REST/OpenAPI modules.

Required Flow

1. Add com.guicedee:guiced-webservices dependency.
2. Define the service contract:

   @WebService(targetNamespace = "http://example.com/hello", name = "HelloService")
   public interface HelloService {
       @WebMethod(operationName = "sayHello")
       @WebResult(name = "greeting")
       String sayHello(@WebParam(name = "name") String name);
   }
   

3. Implement the service:

   @WebService(endpointInterface = "com.example.ws.HelloService",
               serviceName = "HelloService",
               portName = "HelloPort",
               targetNamespace = "http://example.com/hello")
   public class HelloServiceImpl implements HelloService {
       @Override
       public String sayHello(String name) { return "Hello " + name; }
   }
   

4. Publish the endpoint during startup via IGuicePostStartup.
5. For WSDL-first, use the CXF codegen plugin (cxf-codegen-plugin).

Features

• JAX-WS code-first or WSDL-first
• CXF configuration: addresses, bindings (SOAP 1.1/1.2), interceptors, logging
• MTOM for binary attachments
• WS-Security (WSS4J)
• Guice DI friendly: bind implementations via SPI/lifecycle
• JPMS + ServiceLoader discovery

Non-Negotiable Constraints

• Use standard JAX-WS annotations for service contracts.
• Endpoint publishing should be done during IGuicePostStartup.
• SPI implementations must be dual-registered (module-info.java + META-INF/services/).
