Sample Service Packages

CnnPortfolio 

Simple service package. CNN Financial Network. Given a stock ticker, this service returns the stock ticker symbol, time, current price, change in its value, and transaction volume. This service specifies:

1. An input section that uses no input namespaces, no aliases, specifies an input adaptor to do some validation of the request and specifically of the specified parameters, specifies rendering directives that maps the input XML schema file to HTML for presentation to service consumer application clients, then the service consumer application transforms the HTTP request back into an XML document that conforms to the request XML schema file specified by the service provider.

Ipfl 

Compound service package. International Portfolio service. Given a stock ticker, this service returns current prices in the supplied currency. This service specifies:

1. An input section that uses no input namespaces, no aliases, no input adaptor, and specifies rendering directives that maps the input XML schema file to HTML for presentation to service consumer application clients, then the service consumer application transforms the HTTP request back into an XML document that conforms to the request XML schema file specified by the service provider.
2. No protocol section.
3. A compound execution adaptor that splits a single message into two messages, applies a list of two XSLT stylesheets by specifying an index that corresponds to the list of transformations to be performed on the original service message, which results in a list of two resulting messages. A conversion currency service and failover finance service are executed as single requests and each of the two messages is merged back into a single message. By modularizing each message, a dependency matrix is utilized that shows the dependencies of the input of each of the modules, thereby controlling the execution flow of each service on each message. The XSLTs are packaged in a jar file and its location specified as a service binary resource in the package section of the service header.
4. No output section.
