Prefix question

I have a schema like the following

 

<xs:schema

targetNamespace="http://ga.afl.com/"

xmlns:xs="http://www.w3.org/2001/XMLSchema"

elementFormDefault="qualified"

attributeFormDefault="unqualified"

xmlns:ga="http://ga.afl.com/"

xmlns:png="http://ga.afl.com/png/"

xmlns:pnr="http://ga.afl.com/pnr/"

xmlns:ct="http://es.afl.com/ct/">

 

      <xs:import namespace=http://es.aflc.com/ct/ schemaLocation="ct.xsd"/>

      <xs:import namespace="http://ga.afl.com/png/" schemaLocation="Png.xsd"/>

      <xs:import namespace="http://ga.afl.com/pnr/" schemaLocation="Pnr.xsd"/>

 

     

      <xs:element name="readGroupRequest" type="ga:GroupIdentifierType"/>

 

      <xs:complexType name="GroupIdentifierType">

            <xs:choice>

                  <xs:element name="pngId" type="xs:integer"/>

                  <xs:element name="batchId" type="png:BatchIDType"/>

                  <xs:element name="groupNumber" type="ct:GroupNumberType"/>

            </xs:choice>

      </xs:complexType>

</xs:schema>

 

After the schema is compiled I do the following

 

SchemaType type = ReadGroupRequestDocument.type;

SchemaProperty[] schemaProperties = type.getElementProperties();

for(int i=0; i < schemaProperties.length; i++)

{

      SchemaProperty schemaProperty = schemaProperties[i];

      QName qName = schemaProperty.getName();

                       

      System.out.println("NamespaceURI: " + qName.getNamespaceURI());

      System.out.println("LocalPart: " + qName.getLocalPart());

      System.out.println("Prefix: " + qName.getPrefix());

}

 

The output of that code is

NamespaceURI: http://ga.afl.com/

LocalPart: readGroupRequest

Prefix:

 

 

What I do not understand is why the prefix is not “ga”.  The schema has this information.

 

I need to get this information out of the schema because the xml I generate must have this prefix.  I will use XMLOptions setSaveSuggestedPrefixes() method but I do not want to hardcode a prefix in my source code.  How else can I get the prefix from the schema?

 

Thanks,
