JAXB Validation Error

Question

Hi,
Iam using JAXB. I get an validation error. When i try to marshal an object to XML. The code is simple as shown below
1. Container.xsd
<?xml version="1.0" encoding="UTF-8"?>
<schema targetNamespace="http://agi.com"
xmlns="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://agi.com"
elementFormDefault="qualified">
<complexType name="ContainerType" abstract="true">
<sequence>
<choice>
<element name="File" type="anyType" />
<element name="Pen" type="anyType" />
</choice>
</sequence>
</complexType>
<element name="Container" type="tns:ContainerType" abstract="true" />
</schema>
2. Holder.xsd
<?xml version="1.0" encoding="UTF-8"?>
<schema targetNamespace="http://agi.com"
xmlns="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://agi.com"
elementFormDefault="qualified">
<include schemaLocation="Container.xsd"></include>
<complexType name="HolderType">
<complexContent>
<restriction base="tns:ContainerType">
<sequence>
<choice>
<element name="File">
<complexType>
<sequence>
<element name="FileName"
type="string">
</element>
<element name="Capacity"
type="integer">
</element>
</sequence>
</complexType>
</element>
<element name="Pen">
<complexType>
<sequence>
<element name="Make"
type="string">
</element>
</sequence>
</complexType>
</element>
</choice>
</sequence>
</restriction>
</complexContent>
</complexType>
<element name="Holder" type="tns:HolderType"></element>
</schema>
Main.java
package test.client;
import java.io.PrintWriter;
import java.io.StringWriter;
import java.math.BigInteger;
import java.util.List;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;
import javax.xml.bind.Validator;
import test.vo.AnyType;
import test.vo.Holder;
import test.vo.ObjectFactory;
import test.vo.HolderType.FileType;
import test.vo.HolderType.PenType;
import com.sun.xml.bind.StringInputStream;
public class Main {
public static void main(String s[]) throws Exception{
JAXBContext ctx = JAXBContext.newInstance("test.vo" );
ObjectFactory obj = new ObjectFactory();
Holder input = obj.createHolder();
FileType file = obj.createHolderTypeFileType();
file.setCapacity( BigInteger.valueOf(35) );
file.setFileName("Accounts");
AnyType any = obj.createAnyType();
List lst = any.getContent();
lst.add(file);
input.setFile(any);
Marshaller marsh = ctx.createMarshaller();
marsh.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,
new Boolean(true));
marsh.setProperty(Marshaller.JAXB_SCHEMA_LOCATION,
"http://agi.com");
Validator validator = ctx.createValidator();
validator.validate(input);
StringWriter sw = new StringWriter();
marsh.marshal(input, new PrintWriter(sw) );
StringBuffer sb = sw.getBuffer();
System.out.println(sb.toString() );
This throws the following exception
DefaultValidationEventHandler: [ERROR]: tag name "test.vo.AnyType" is not allowed. Possible tag names are: <test.vo.HolderType.FileType>
Location: obj: test.vo.impl.HolderImpl@1cd8669

at test.vo.impl.runtime.ValidatorImpl.validate(ValidatorImpl.java:104)
at test.client.Main.main(Main.java:63)
However if i commentout the validation it works fine yeilding the
following result
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Holder xsi:schemaLocation="http://agi.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://agi.com">
<File>
<FileName>Accounts</FileName>
<Capacity>35</Capacity>
</File>
</Holder>
Which look good conforming to the schema above
It willbe helpful if someout could point out the mistake iam doing
Please help

Answer 1

I changed the code
marsh.setProperty(Marshaller.JAXB_SCHEMA_LOCATION,"http://agi.com Holder.xsd");
to
marsh.setProperty(Marshaller.JAXB_SCHEMA_LOCATION,"http://agi.com E:/Agilan/Holder.xsd");
But still the same error.
I have validated the generated xml using XMLObjective. It says the generated xml is valid against the schema.
I really dont know why the JAXB validation fails?
Please help
