represents that the unique identifier is auto generated by the database. defines the unique identifier or primary key of the relation. For a class to be an entity, it has to be annotated Persistence provider (here, EclipseLink is used as a persistence provider, which comes bundled with Glassfish) recognizes it and transforms it into an entity and not just a simple POJO. This class actually maps to a table in the database. Except for the annotations used, this class is nothing more than a simple POJO. The Web Service producer in the example has a project structure and three classes as follows:įig 3: Project structure of SOAP web service producerġ) Product.java: This class represents the Product entity. Thus our project structure can be illustrated as in Fig 2.įig 2: Hypothetical scenario demonstrating SOAP web service usage Creating Web Service Producer Suppose, a web service producer/server provides a web method to display a list of products, and the client/consumer is a simple swing desktop application that wants to display the list of products in a table format.

Without delving into the core of SOAP technology lets get our hands dirty in creating one.įig 1: SOAP Request/Response Writing SOAP Web Service from Scratch in Java EE7 One can almost overlook the intricacies of creating SOAP Web Service and focus on the business logic while Java takes care of the most on behalf of the programmer. Though it may seem overwhelming at first, with so many complex technologies intermingling together in a perfect symphony, creating SOAP web service in Java is actually pretty simple. SOAP web service depends upon a number of technologies (such as UDDI, WSDL, SOAP, HTTP) and protocol to transport and transform data between a service provider and the consumer.
