There might be situations where you would want to modify the attributes of the embedded class (eg. Address) within an embedding class (eg. User), for instance, changing the database column name for a field.

We can use @AttributeOverride annotation to override the details of a field of the embedded class and then enclose all such @AttributeOverride annotations inside @AttributeOverrides annotation.

A web container like tomcat can deploy servlets, jsps and web services.

Important points about deploying bottum up web services in Tomcat

• Web components are generally deployed in the web container as war files.

  • These war files might contain standard configuration files such as web.xml and vendor specific configuration files such as sun-jaxws.xml.

Introduction to SOA

Wikipedia defines SOA as "Service-oriented architecture (SOA) is a software design and software architecture design pattern based on discrete pieces of software providing application functionality as services to other applications. This is known as Service-orientation. It is independent of any vendor, product or technology.".

Web services can be created using two ways: top-down development and bottom-up development.

Top-down web services development

• Top-down Web services development involves creating a WSDL and then creating the Web service using the WSDL file. 

  • In top-down approach, first you design the implementation of the Web service by creating a WSDL file. You can then create the Web service skeleton Java classes from the wsdl, and add the required code.
