JSR 181 Web Service

In the last post I have used simple Web Service to test Spring-WS. Now I'm going to explain the implementation of this service.
The service is based in XFire and JSR 181 annotations.

First, the Book class, that represent the model.

package net.dahernan.model;

public class Book {
 
 protected String title;
 protected String isbn;
 protected String author;
 protected Double price;
 
 // ... getters and setters
}

Next, the BookService class (yeah a class not an interface).

package net.dahernan.service;

import java.util.ArrayList;
import java.util.List;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

import net.dahernan.model.Book;

@WebService
public class BookService {

 protected Book getMockBook(){
  Book book = new Book();
  book.setAuthor("Matt Raible");
  book.setTitle("Spring Live");
  book.setIsbn("12345");
  book.setPrice(12.22);
  return book;
 }
 
 protected List getMockBooks(){
  List result = new ArrayList();
  Book book = new Book();
  book.setAuthor("Matt Raible");
  book.setTitle("Spring Live");
  book.setIsbn("12345");
  book.setPrice(12.22);
  result.add(book);
  
  book = new Book();
  book.setAuthor("Martin Fowler");
  book.setTitle("Planning Extreme Programming");
  book.setIsbn("12346");
  book.setPrice(18.00);
  result.add(book);
  return result;
 }

 @WebMethod
 @WebResult(name="Book")
 public Book findBook(@WebParam(name="isbn")String isbn) {
  Book book = this.getMockBook();
  book.setIsbn(isbn);
  return book;
 }

 @WebMethod
 @WebResult(name="Books")
 public List getBooks() {  
  return getMockBooks();
 }

}

The class is annotated with @WebService. The first two methods are Mocks, and "getBooks" and "findBooks" are the methods exposed in service.

It's good practice annotate the result with @WebResult and the parameters with @WebParams to obtain an human readable WSDL.

Finally, the services.xml to configure my POJO.

<beans>
<service xmlns="http://xfire.codehaus.org/config/1.0">
 <name>BookService</name>
 <namespace>http://dahernan.net/BookService</namespace>
 <serviceClass>net.dahernan.service.BookService</serviceClass>
 <serviceFactory>#jsr181ServiceFactory</serviceFactory>
</service>

<bean id="config"
 class="org.codehaus.xfire.aegis.type.Configuration">
 <property name="defaultExtensibleElements" value="false" />
 <property name="defaultExtensibleAttributes" value="false" />
 <property name="defaultNillable" value="false" />
 <property name="defaultMinOccurs" value="1" />
</bean>

<bean name="jsr181ServiceFactory"
 class="org.codehaus.xfire.annotations.AnnotationServiceFactory">
 <constructor-arg ref="xfire.transportManager" index="0" />
 <constructor-arg ref="config" index="1"
 type="org.codehaus.xfire.aegis.type.Configuration" />
</bean>

</beans>

The generated WSDL looks like a contract-first WSDL ;)
