Wrong Case or ClassCastException

Question

Hello everyone
I use JWSDP2.0, JDK is jdk1.5.0_12
I have tried to generate class by the command:
xjc -p test.jaxb poll.xsd
Following is the schema
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
     <xsd:element name="Poll" type="Poll"/>
     <xsd:complexType name="Poll">
          <xsd:sequence>
               <xsd:element name="queryName" type="xsd:string"/>
               <xsd:element name="params" type="QueryParams"/>
          </xsd:sequence>
          <xsd:anyAttribute processContents="lax"/>
     </xsd:complexType>
     <xsd:complexType name="QueryParams">
          <xsd:sequence>
               <xsd:element name="param" type="QueryParam" minOccurs="0" maxOccurs="unbounded"/>
          </xsd:sequence>
     </xsd:complexType>
     <xsd:complexType name="QueryParam">
          <xsd:sequence>
               <xsd:element name="name" type="xsd:string"/>
               <!-- See note in EPCIS spec text regarding the value for this element -->
               <xsd:element name="value" type="xsd:anyType"/>
          </xsd:sequence>
     </xsd:complexType>     
</xsd:schema>I modify the poll.java, and add @XmlRootElement in front of the class declaration.
Then I write code to test marshall and unmarshall
package test;
import java.util.List;
import java.io.*;
import javax.xml.bind.*;
import org.w3c.dom.*;
import test.jaxb.*;
public class JAXBTest {
     public static void main(String[] args){
          try {
               JAXBContext context = JAXBContext.newInstance("test.jaxb");
               ObjectFactory factory = new ObjectFactory();
               Marshaller marshal = context.createMarshaller();
               marshal.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
               Unmarshaller unmarshal = context.createUnmarshaller();
               Poll poll = factory.createPoll();
               poll.setQueryName("Query1");
               QueryParams params = factory.createQueryParams();
               List list = params.getParam();
               QueryParam param = factory.createQueryParam();               
               param.setName("Name");
               param.setValue("David");
               list.add(param);
               poll.setParams(params);
              OutputStream os = new FileOutputStream( "poll.xml" );
              marshal.marshal( poll, os );     
              marshal.marshal(poll,System.out);
              Poll input = (Poll)unmarshal.unmarshal( new File( "poll.xml" ) );
              System.out.println(input.getQueryName());
          } catch (Exception e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
}I found the root element is generated to "poll", not the schema defined "Poll"
But marshall and unmarshall are ok.
In order to comform the schema, I modify Poll.java again.
Change @XmlRootElement to @XmlRootElement(name = "Poll")The result is I can generate the right case element now("Poll").
But I get the exception simultaneously, unmarshall is not ok
java.lang.ClassCastException: javax.xml.bind.JAXBElement
     at test.JAXBTest.main(JAXBTest.java:29)
is there any resolution to solve wrong case problem and make marshall/unmarshall ok?

Hi,
As far as I know Oracle are porting Developer R6 to Linux.
We're also anxiously waiting for it to be out.
It should be out in 2 or 3 months.
About CASE I don't thing anyone will port it to linux.
Regards,
Michael
