Novell exteNd Web Services SDK 5.0 DataSheet

Comprehensive Web Services Technology

Novell exteNd WSSDK is a complete XML RPC environment for building, running, and invoking Web Services using Java:

• supports writing Web Service interface using WSDL as well as Java RMI
• complete set of compilers to convert WSDL to Java and vice versa, and for generating client and server XML RPC glue (stubs/skeletons) code
• high performance and scalable SOAP 1.1 runtime over HTTP transport
• extensive support for producing XML from Java Objects and vice versa

Java RMI Programming Model

Novell exteNd WSSDK brings Java RMI's ease of use to the world of Web Services. Invoking a Web Service is the same as invoking a Remote object, and, implementing a Web Service is the same as implementing a Remote interface. The technology completely shields the programmer from the fact that it is talking to a Web Service, possibly described using WSDL, and that the XML messages are being exchanged under the covers.

• if starting with Java RMI, the rmi2soap compiler generates SOAP stubs and skeletons, and rmi2wsdl compiler generates WSDL
• if starting from WSDL, the wsdl2java compiler generates Java RMI interface and SOAP stubs/skeletons
• the stubs are created using a service, which is looked up by the client using standard Java JNDI APIs
• the Java <-> XML Type mapping allows users to do custom serialization, as well as exchanging "raw" XML documents

J2EE Deployment and Server Independence

The Novell exteNd Web Services SDK generated skeletons are Java servlets. They can be deployed in any J2EE Web Application container using standard J2EE Web Application deployment. They can also benefit from the standard J2EE security features like authentication, access control, and confidentiality using SSL.

High Performance and Scalability

Novell exteNd WSSDK has a very low footprint and high performance runtime with a very flexible architecture. Initial tests have shown the Web Services written using Novell exteNd Web Services SDK and deployed on a commercial J2EE application server to be able to handle several hundred requests/second.
