CPI has completed a project for Naval Criminal Investigative Service (NCIS) converting the current legacy Nlets dual-socket interface and associated driver to the new Nlets Web Services interface and associated driver.

The conversion from the current IP Sockets interface to the Web Services interface is aligned with the direction of Nlets to sunset the existing dual-socket protocol. Text formatted Nlets messages will be changed to text formatted and encapsulated within an XML wrapper, as required by the Nlets Web Services interface.

CPI worked with NCIS to convert the existing dual-socket interface to the new Nlets Web Service interface using the published specifications from Nlets. In this effort, the interface transport mechanism was converted to industry-standard web services and the supporting interface driver was updated to the newest version to support the new interface.

This web services interface is defined through the use of Web Service Definition Language (WSDL). WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information.
