Thanks to Hussain for creating this tutorial. I am just extending his learning with some additions of mine.

The Sample WebService will return Credit Rating of the customer if the customer Id is Valid else it will give response as Invalid Customer Id

1) Open JDeveloper, Create New Application and Project as shown below

2) Create a Java Class, Right Click on Project->New->General->JavaClass

3) Enter Class Name as CreditRating and Package name as

4) Write a Method called getCreditRating inside the class CreditRating class.
the method should accept customer id and return a CreditRating of the customer.


public class CreditRating implements Serializable
    public CreditRating()
     * Do read this link for help 
     * in case of issues :
     * @webmethod 
    public String getCreditRating(String customerId)
        String rating;
        if("abc".equalsIgnoreCase(customerId) ||
           "xyz".equalsIgnoreCase(customerId) )
           else if("pqr".equalsIgnoreCase(customerId))
                rating = "Invalid Customer id";
           return rating;

5) Compile your Project, After Successful Compilation, Right Click your Project->Business Tier-> Web Services-> Java Web Service
