5-4 Getting Started With JAX-WS Web Services for Oracle WebLogic Server
xsd:complexType or JavaBeans. The WebLogic Web services Ant tasks, such as
jwsc and clientgen, automatically generate the data binding artifacts needed to
convert the user-defined data types between their XML and Java representations. The XML representation is used in the SOAP request and response messages, and the Java
representation is used in the JWS that implements the Web service.
The following sections describe the built-in and user-defined data types that are supported by JAXB:
■
Section 5.3.1, Supported Built-In Data Types
■
Section 5.3.2, Supported User-Defined Data Types
5.3.1 Supported Built-In Data Types
The following sections describe the built-in data types supported by WebLogic Web services and the mapping between their XML and Java representations. As long as the
data types of the parameters and return values of the back-end components that implement your Web service are in the set of built-in data types, WebLogic Server
automatically converts the data between XML and Java.
When using user-defined data types, then you must create the data binding artifacts that convert the data between XML and Java. WebLogic Server includes the jwsc and
wsdlc Ant tasks that can automatically generate the data binding artifacts for most
user-defined data types. See Section 5.3.2, Supported User-Defined Data Types
for a list of supported XML and Java data types.
5.3.1.1 XML-to-Java Mapping for Built-in Data Types
The following table lists alphabetically the supported XML Schema data types target namespace http:www.w3.org2001XMLSchema and their corresponding Java
data types. For a list of the supported user-defined XML data types, see Section 5.3.1.2,
Java-to-XML Mapping for Built-In Data Types.
