  1. Session id: 40053 Develop, Deploy and Manage Web services with OracleAS 10g Venky Ravipati Principal Product Manager Oracle Corporation Eric Rajkovic Principal Member Technical staff Oracle Corporation

  2. Agenda • Introduction to Web Services • OracleAS 10g Web Services • Web services Interoperability • OracleAS 10g Roadmap

  3. Overview • J2EE Overview • EJB Overview • Entity Bean Lifecycle for the DBAs • Persistence Options and related concerns • Optimizing CMP Entity beans for Oracle database • JMS and Oracle database • Other DBA Considerations • Additional Resources and Next Steps • Complete Your Survey (Session Id#40019)

  4. Web Services Versus Web Applications Web Services Web Application • XML/SOAP • Program-to-program interaction • Static or dynamic integration • Re-usable service • HTML • User-to-program interaction • Static integration of components • Single use service

  25. What About Interoperability? Oracle IBM XML SOAP WSDL UDDI LDAP, SMTP, … J2EE .Net BEA Microsoft Sun Others

  26. Web Services Interoperability Issues • Type Encoding • explicit typing of parameters (eg., "xsd:integer" vs "xsd:int" ) • SOAPAction Header • Some implementations support both SOAPAction values of "" and null, while others do not • Message Parameters • Some toolkits have the ability to set multiple out params, while most toolkits can process one and only one out param • Order of parameters for return types on the client side. • SOAP Envelope • Encoding style, envelope level or body level? • Namespace qualification • IDs and Href

  27. Web Services Interoperability • SOAPBuilders • Grassroots organization • Canonical set of tests, testing interoperability on live implementations • soapbuilders@yahoo.com • WS-I.org • Industry initiative for Web services interoperability • Open to any organization committed to Web services • Promote and accelerate adoption, deployment of Web services

  28. WS-I Profiles • Names groups of Web services specifications for interoperability purposes • Defines how best to use combinations of specifications together • Enables industry to define interoperability levels Phase II “Security andReliability” XML Digital Signature XML Encryption WS-Security HTTP-R SAML XACML … Phase 1 “Connection” XML Schema SOAP WSDL UDDI Phase III “Enterprise” Provisioning Transactions Workflow Systems management … WS-I Basic Profile Today
