Writing web service to read/write data from app database

There are web services to reach another app database to read data as XML. Java is required. I need you to write web services in java and run it to get data from app database. Web Services platform employs Web-based technology to handle requests from external programs. External client programs use the application Web Services by creating a request and sending it to the application server using the SOAP protocol which is essentially XML over HTTP.

Web Services uses a contract first approach in which WSDL files are used to describe itself to requesting applications. The WSDL uses the Document/Literal Wrapped style to describe the services and their operations. The Document/Literal Wrapped style indicates that the application Web Services exchange messages as SOAP envelopes that contain a message body and an optional message header. The message body is comprised of an XML document that is constrained by a WSDL description of the web service. Furthermore, the message body contains an operation name that defines the outer wrapper element for both the request and response messages. The contract first approach is supported by a broad-based set of tools, promotes stability, and enables you to generate your own API.

The application uses WS-Security UsernameToken Profile to authenticate your client program's requests by default.

Skills: XML, Java, Web Services, API, SOAP API
