javax.xml.bind.annotation
Annotation Type XmlSchema


@Retention(value=RUNTIME)
@Target(value=PACKAGE)
public @interface XmlSchema

Maps a package name to a XML namespace.

Usage

The XmlSchema annotation can be used with the following program elements:

This is a package level annotation and follows the recommendations and restrictions contained in JSR 175, section III, "Annotations". Thus the usage is subject to the following constraints and recommendations.

Example 1: Customize name of XML namespace to which package is mapped.

    @javax.xml.bind.annotation.XmlSchema (
      namespace = "http://www.example.com/MYPO1"
    )
    
    <!-- XML Schema fragment -->
    <schema
      xmlns=...
      xmlns:po=....
      targetNamespace="http://www.example.com/MYPO1"
    >
    <!-- prefixes generated by default are implementation
            depedenent -->
 

Example 2: Customize namespace prefix, namespace URI mapping

    // Package level annotation
    @javax.xml.bind.annotation.XmlSchema (
      xmlns = { 
        @javax.xml.bind.annotation.XmlNs(prefix = "po", 
                   namespaceURI="http://www.example.com/myPO1"),

        @javax.xml.bind.annotation.XmlNs(prefix="xs",
                   namespaceURI="http://www.w3.org/2001/XMLSchema")
      )
    )
 
    <!-- XML Schema fragment -->
    <schema
        xmlns:xs="http://www.w3.org/2001/XMLSchema"
        xmlns:po="http://www.example.com/PO1"
        targetNamespace="http://www.example.com/PO1">
 
 

Example 3: Customize elementFormDefault

    @javax.xml.bind.annotation.XmlSchema (
      elementFormDefault=XmlNsForm.UNQUALIFIED
      ...
    )
 
    <!-- XML Schema fragment -->
    <schema
        xmlns="http://www.w3.org/2001/XMLSchema"
        xmlns:po="http://www.example.com/PO1"
        elementFormDefault="unqualified">
