Using the SOAP Web Service APIs

KonaKart has four major interface types - the direct POJO interface and, if you have the Enterprise Edition, the JSON interface, the JAXWS SOAP interface and the RMI interface. The Business Edition has all the interfaces the Enterprise Edition has except RMI. Each of these support exactly the same interface calls. Which one you choose will depend on many factors but the best performance is likely to come from the direct interface, whereas the JAXWS, RMI and JSON interfaces give greater flexibility in distributed implementations and inter-operability. Using JSON over low-bandwidth networks and on mobile devices will probably give the best performance in these environments.
