  1. Web Services Examples HTTP Tunnel/Monitor $ corej2ee tools tunnel –Dlocalport=8001 –Dhost=localhost –Dport=7001 Web Services Examples

  2. RMI Easy When Client/Server are both Java Standard API Java Centric Proprietary Implementations RMI/IIOP added basic interoperability, but no transactions or security CORBA Standard API Java, C++, Many More Interoperable Difficult HTTP Standard TCP/IP Primarily Text Easy Sockets and Servlets Mail Header Body Attachments XML data-oriented How Can We Communicate Within J2EE? Web Services Examples

  3. Web Services • A standard way to request a service and get a reply between two or more independent parties • Combines • XML • descriptive • no client/server implementation coupling • different languages and programming models • Simple Object Access Protocol (SOAP) schema added to permit messaging • HTTP/HTTPS • standard protocol that is accepted through firwalls • Servlets • standard deployment model for code Web Services Examples
