Java EE (Java Enterprise Edition) General Discussion

Hi,

I am getting an error while parsing(unmarshallling) the xml using JAXB thru XSD validation.

Here is the xsd, that I am using for the validation followed by the xml sample and exception that I am getting.

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

	<xs:complexType name="process_variable_type">
	      <xs:sequence>
		<xs:element name="variable_name" type="xs:string"/>
		<xs:element name="label" type="xs:string"/>
		<xs:element name="value" type="xs:string"/>
		<xs:element name="previous_value" type="xs:string"/>
		<xs:element name="format" type="xs:string"/>
	      </xs:sequence>
	</xs:complexType>
	
	<xs:complexType name="text_field_type">
	  <xs:complexContent>
	    <xs:extension base="process_variable_type">
	    </xs:extension>
	  </xs:complexContent>
	</xs:complexType>
	
	<xs:complexType name="part_type">
	  <xs:sequence>
	   <xs:choice>
		<xs:element name="textFieldElement" type="text_field_type" /> 
	   </xs:choice>
	  </xs:sequence>
	  <xs:attribute name="name" type="xs:string" />
	</xs:complexType>
	
	<xs:element name="variable">
	  <xs:complexType>
	   <xs:sequence>
		<xs:element name="part" type="part_type" minOccurs="1" maxOccurs="1" /> 
	   </xs:sequence>
	  <xs:attribute name="dataIncluded" type="xs:string" />
	  <xs:attribute name="hasData" type="xs:string" />
	  <xs:attribute name="name" type="xs:string" />
	  <xs:attribute name="version" type="xs:string" />
	  </xs:complexType>
	</xs:element>
	
</xs:schema>

Sample XML:

<variable dataIncluded="yes" hasData="true" name="V1" version="25">
   <part name="textFieldElement">
      <textFieldElement xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/" xmlns:abx="http://www.activebpel.org/bpel/extension" xmlns:bpws="http://schemas.xmlsoap.org/ws/2003/03/business-process/" xmlns:ext="http://www.activebpel.org/2.0/bpel/extension" xmlns:ns1="urn:ValueDisplayer" xmlns:ns2="urn:ValueProvider" xmlns:ns3="Invalid Document" xmlns:ns4="http://temp" xmlns:ns5="http://active-endpoints.com/services/order" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
         <variable_name>Variable1</variable_name>
         <label>Label2</label>
         <value>Value1</value>
         <previous_value>prevValue1</previous_value>
         <format>format1</format>
         <form_element_type>formElement1</form_element_type>
      </textFieldElement>
   </part>
</variable>

Error that I am getting is:

If I remove the following attribute in the textFieldElement from the sample, then I am able to unmarshal it successfully.

xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/"

But at the runtime, I cannot avoid this attribute in the XML message which I should unmarshal it.

Need help to resolve this.
