4.6.1 General Guidelines for Upgrading to Oracle WebLogic Server JAX-RPC and JAX-WS Web Services
In general, to upgrade your Web services from OC4J to Oracle WebLogic Server, you must upgrade your application to use the equivalent Java Web services API on
WebLogic Server: Oracle Web Cache
Invalidation The Web Cache Invalidation API can
continue to be used by ensuring that the appropriate OracleAS 10g jar file is available
to the application when deployed to WebLogic Server.
An updated, but fully backward compatible, version of this API is also available in as
part of the JRF domain template. Section 4.5.1, APIs Available With
the Java Required Files JRF Domain Template
OracleAS Web Services Oracle Web Services Proxy
Oracle Web Services SOAP Oracle Web Services UDDI
Client Any application using OracleAS Web
Services will require modification to use the equivalent set of Oracle Fusion Middleware
or WebLogic Server APIs and features. More specifically:
■
Applications using the OracleAS Web Services, Oracle Web Services Proxy, or
Oracle Web Services SOAP API must be modified to use the standard based
JAX-RPC or JAX-WS Web Services APIs of WebLogic Server.
■
Applications using the Oracle Web Services UDDI Client API must be
modified to use the UDDI v1, v2, or v3 compliant Oracle Service Registry

OC4J Support for JSP Any application using this API will require
modification to use the equivalent set of Java Standard Tag Library JSTL tags.

■
For most OC4J Web services applications, this means upgrading from OC4J JAX-RPC Web services to Oracle WebLogic Server JAX-RPC Web services. In
general, the JAX-RPC upgrade process consists of re-generating the Java artifacts on Oracle WebLogic Server to the identical underlying Java business logic using
Oracle WebLogic Server Web services tooling.
■
If you are using an older release of OC4J, where Web services standards did not exist within Java EE, Oracle recommends that you upgrade to the Java EE 5.0
standard JAX-WS on Oracle WebLogic Server.
For more information, see:

4.6.2 Generating Oracle WebLogic Server Web Services From an OC4J WSDL
For absolute fidelity to a specific OC4J Web services public API its WDSL, you also can regenerate the Web services on WebLogic Server from the OC4J WSDL and deploy
the resulting Web service on WebLogic Server. This process is referred to as the top-down approach to developing Web services.
After producing the equivalent and deployable Web service artifacts on Oracle WebLogic Server, you can then apply the equivalent quality of service QOS
capabilities, such as WS-Security and WS-ReliableMessaging as a secondary administrative operation.
4.6.3 Web Services Specifications Supported by OC4J and Oracle WebLogic Server
Table 4–4 compares the Web services standard specifications supported by OC4J and
Oracle WebLogic Server. Note that Oracle WebLogic Server supports all of the Web services standards and specifications supported by OC4J, except for WS-Reliability.
Note that this table is provided for comparison purposes only. For the most up-to-date information about the standards supported by Oracle WebLogic Server, refer to the
Oracle WebLogic Server documentation and to the Oracle WebLogic Server information available on the Oracle Technology Network OTN.
