JAXB - Unexpected end of element {} - UnmarshalException Exception

Question

Hi
I am using Jaxb 1.0 Beta on AIX an I am getting javax.xml.bind.UnmarshalException exception when I try to unmarshall XML document. XML document and schema are valid ( I generated both using XML spy )
Interestingly, the code works fine on windows 2000 but when I put the jar ,XML schema and xml document on unix it throws Unmarshall exception.
Here's what I am trying to do.
Code :
JAXBContext jc =
JAXBContext.newInstance( context,
new com.xyz.retail.app.points.pgp.JAXBClassLoader());
if(jc != null)
     System.out.println("Got the context");
else
     System.out.println("Error in getting context");
System.out.println("");
// create an Unmarshaller
Unmarshaller u = jc.createUnmarshaller();
System.out.println("Created the Unmarshaller");
System.out.println("");
// Unmarshal securities document into Java content tree
SecurityInfo securityInfo =
     (SecurityInfo)u.unmarshal( new FileInputStream( secFile ) );
System.out.println("Unmarshaled the Document");
System.out.println("");
Schema :
<?xml version="1.0" encoding="UTF-8"?>

I'm having error. I'm using the lastest JWSDP (1.3) with JDK 1.4.2
Here is my XML file:
<?xml version="1.0"?>
<dataQA>
<table name="ELECTORAL_DISTRICT" >
<rules>
<rule number="1.1" description="Check if we have 301 EDs" >
<query result="301" >
     <sql>SELECT COUNT(ED_ID) FROM ELECTORAL_DISTRICT</sql>
</query>
</rule>
<rule number="1.3" description="All fields must be populated" >
<query result="0" >
<sql>SELECT COUNT(ED_ID) FROM ELECTORAL_DISTRICT WHERE ED_CODE IS NULL OR ED_NAMEE IS NULL OR ED_NAMEF IS NULL</sql>
</query>
</rule>
</rules>
<reports>
<report number="1.4" name="Listing of EDs" file="ed_list" format="HTML" >
     <column name="ED_ID" label="ID" ></column>
     <column name="ED_CODE" label="Code" ></column>

     <column name="ED_NAMEF" label="French Name" ></column>
     <column name="PRVNC_ID" label="Province ID" ></column>
</report>
</reports>
</table>
</dataQA>
And my shema:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="dataQA" type="DataQAType"/>
<xsd:complexType name="DataQAType">

<xsd:element name="sql" type="xsd:string" />

</xsd:schema>
I get the following exception:
DefaultValidationEventHandler: [FATAL_ERROR]: Unexpected end of element {}:report
Location: line 23 of file:/D:/Revise2.5/DataQA/config/test.xml
javax.xml.bind.UnmarshalException: Unexpected end of element {}:report
I'm currenlty in the processing of writting parser with DOM since I haven't found the yet. Is this a bug or I'm doing something wrong.
Thanks in advance for the reply,
