Creating a Web service from an EJB bean and a WSDL file
You can use annotations to associate an implementation EJB bean with an existing WSDL service contract.
Prerequisites:
- Your workspace must contain an EJB 3.0 bean that has been annotated as a Web service (it must contain the @Stateless annotation).
- You must have an existing Web Services Description Language (WSDL) service contract.
To create a Web service:
- In the Enterprise Explorer view, double-click your EJB bean to open the file in the Java™ editor.
- In the editor or Annotations view, specify a value for the wsdlLocation attribute of the @WebService annotation. This value should be the Web address of the WSDL service contract that you want to associate with your bean.
- Optional: Use annotations to associate other Java elements with WSDL elements. For example, you might associate a Java method name with a WSDL operation name, or a Java parameter with a WSDL schema element. For detailed information about these and other annotations, see the related reference.
- Save your EJB file.
Postrequisite: Now you can generate a Web service from your annotated Enterprise bean by publishing it to a server.
Note: As you use annotations to associate your EJB bean with a WSDL service contract, the JAX-WS annotations processor ensures that your Java code is consistent with the WSDL contract as required by the JAX-WS and JSR-181 standards. If there are inconsistencies, you will see warnings or errors in the code, along with suggestions for correction.
