Types Supported by JAX-WS

JAX-WS delegates the mapping of Java programming language types to and from XML definitions to JAXB. Application developers don’t need to know the details of these mappings but should be aware that not every class in the Java language can be used as a method parameter or return type in JAX-WS.

The following sections explain the default schema-to-Java and Java-to-schema data type bindings:

Schema-to-Java Mapping

The Java language provides a richer set of data types than XML schema. Table 31-1 lists the mapping of XML data types to Java data types in JAXB.
