Question

What are the various approaches available for developing SOAP based web services?

Answer

There are two different methods available for developing SOAPbased web services, which are explained below: Contract-first approach: the contract is first defined by XML and WSDL, and then Java classes are derived from the contract. Contract-last approach: Java classes are first defined, and then the contract is generated, which is normally the WSDL file from the Java class. ""Contract-first"" method is the most popular approach.
