Spring Web Services

Exercise: Todo SOAP Service (Contract-first)

The objective of this exercise is to implement a SOAP based todo web service based on a WSDL document.

Assignment

1. WSDL document
   • Save the WSDL document of the code-first web service to the resource folder
   • Extract the type definitions from the WSDL document into a separate XML Schema document
   • Change the XML Schema such that the ID is a required attribute of the todos and the title a required non-empty element
2. Code generation
   • Remove the exception class and rename the entity Todo to TodoEntity
   • Use the Maven plugin cxf-codegen-plugin to generate the Java artifacts from the local WSDL document (see Apache CXF documentation)
3. Service implementation
   • Remove all the JAX-WS annotations from the TodoListImpl class and implement the generated web service interface
   • Annotate the class with the @WebService annotation using the endpointInterface and wsdlLocation elements
   • Annotate the class with the @SchemaValidation annotation to activate XML schema validation
   • Use the TypeMapper utility class to convert the occurring date and todo types where necessary
4. Testing
   • Verify the published WSDL document at http://localhost:8080/soap/todolist?wsdl
   • Use the SoapUI utility to send SOAP requests to the web service
