Download :jdom-1.0.jar
For Spring you can download its latest version say 2.5.
Step 2: Creating a Project
- Open your IDE ( I am using Eclipse) and create a Web project. Lets say with Name CXFExample.
- Create a package say “com.your.company.service”
- Create a POJO class with a name say “Product”. And include some properties like productName etc.
1: package com.your.company.service;
2:
3: import org.apache.cxf.aegis.type.java5.IgnoreProperty;
4:
5: public final class Product {
6: private String itemName;
7: private String category;
8: private double price;
9: private String details;
10:
11: public Product() {
12: }
13:
14: public Product(String itemName, String category, double price,
15: String details) {
16: this.itemName = itemName;
17: this.category = category;
18: this.price = price;
19: this.details = details;
20: }
21:
22: public String getItemName() {
23: return itemName;
24: }
25:
26: public void setItemName(String itemName) {
27: this.itemName = itemName;
28: }
29:
30: public String getCategory() {
31: return category;
32: }
33:
34: public void setCategory(String category) {
35: this.category = category;
36: }
37:
38: public double getPrice() {
39: return price;
40: }
41:
42: public void setPrice(double price) {
43: this.price = price;
44: }
45:
46: @IgnoreProperty
47: public String getDetails() {
48: return details;
49: }
50:
51: public void setDetails(String details) {
52: this.details = details;
53: }
54:
55: }
Note that we used one Annotation from Aegis. Its just to get some idea about that annotation. As you know Aegis is using for data binding. As the annotation denotes if we are mentioning it is not needed in the WSDL file.
- Creating the Service Interface
1: package com.your.company.service;
2:
3: import java.util.List;
4:
5: import javax.jws.WebParam;
6: import javax.jws.WebService;
7:
8: @WebService
9: public interface ProductService {
10:
11: List<Product> getProducts();
12:
13: void addProduct(@WebParam(name = "product") Product product);
14:
15: public void addProducts(@WebParam(name = "products") List<Product> products);
16:
17: }
Here we are using @WebService annotation and @WebParam Annotations. They are JAX-WS annotations.
@WebService is using to denote this Interface as the Web Service Interface. So while creating WSDL file this will consider.
@WebParam is using to name the Arguments in the WSDL file. Default it will be like Arg0, Arg1 etc. But if we are giving some names then that will be more identifiable in the WSDL.
- Create the Service Implementation class
1: package com.your.company.service;
2:
3: import java.util.ArrayList;
4: import java.util.List;
5:
6: import javax.jws.WebParam;
7: import javax.jws.WebService;
8:
9: @WebService(endpointInterface = "edu.web.service.ProductService")
10: public final class ProductServiceImpl implements ProductService {
11:
12: public List<Product> getProducts() {
13: List<Product> products = new ArrayList<Product>();
14: products.add(new Product("SpringInAction", "Manning", 200,
15: "Book about Spring"));
16: products.add(new Product("EJB3InAction", "Manning", 200,
17: "Book about EJB3"));
18: return products;
19: }
20:
21: @Override
22: public void addProduct(Product product) {
23: System.out.println(product);
24: }
25:
26: @Override
27: public void addProducts(@WebParam(name = "products") List<Product> products) {
28: for (Product product : products) {
29: System.out.println(product);
30: }
31: }
32: }
Here we are writing the Impls of our Interface methods. @WebService
annotation is marking this class as a web service implementation
In the next PART we will be discussing about the Configurations.

Lijin,
Hope you remember me. I was trying to set up and build a webservice application based on your post. I am getting some problem while deploying it to the server. Due to the schema defined in applicationContext.xml, it is failed to initialize. I am getting bellow exception.
Exception:
schema_reference.4: Failed to read schema document ‘http://www.springframework.org/schema/beans/spring-beans-3.0.5.xsd’, because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not .
Plz help me out. How can i resolve this.
I believe you have a typo in your code:
@WebService(endpointInterface = “edu.web.service.ProductService”)
should be
@WebService(endpointInterface = “com.your.company.service.ProductService”)
Hi, I would like to know how apache cxf resolves inheritance when returning an object. Lets say that CustomProduct inherits from product, and you return a collection of Products, why it doesnt resolve the CustomProducts and sees all like Product?I did it with glassfish but I can’t do it with apache cxf!
