OpenSSO Enterprise data services are built using a Java package called com.sun.identity.liberty.ws.dst. OpenSSO Enterprise provides this package for developing custom services based on the Liberty ID-WSF-DST. Additional information about these interfaces can be found in the Sun OpenSSO Enterprise 8.0 Java API Reference.
OpenSSO Enterprise contains two packages based on the Liberty ID-WSF-DST. They are:
com.sun.identity.liberty.ws.dst provides classes for the Client SDK.
com.sun.identity.liberty.ws.dst.service provides a handler class that can be used by any data service that is built using the Liberty ID-SIS Specifications. The DSTRequestHandler class is used to process query or modify requests sent to an identity data service. It is an implementation of the interface com.sun.identity.liberty.ws.soapbinding.RequestHandler.
