renaming a class results to "A Manager for test.MediaType is not declared." error
---------------------------------------------------------------------------------

         Key: JAXME-71
         URL: http://issues.apache.org/jira/browse/JAXME-71
     Project: JaxMe
        Type: Bug
    Versions: 0.5    
 Environment: Windows XP
JDK 1.5.0_04
JaxME 0.5
    Reporter: Thomas Bielagk
    Priority: Blocker


Suggest the following xsd file:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb">
	<xs:annotation>
		<xs:appinfo>
			<jaxb:schemaBindings>
				<jaxb:nameXmlTransform>
					<jaxb:elementName suffix="Element"/>
				</jaxb:nameXmlTransform>
			</jaxb:schemaBindings>
		</xs:appinfo>
	</xs:annotation>
	<xs:element name="Config">
		<xs:complexType>
			<xs:sequence>
				<xs:element ref="Media" minOccurs="0" maxOccurs="unbounded"/>
				<xs:element ref="MediaType" minOccurs="0" maxOccurs="unbounded"/>
			</xs:sequence>
		</xs:complexType>
	</xs:element>
	<xs:element name="Media">
		<xs:complexType>
			<xs:attribute name="Text" type="xs:string" use="required"/>
		</xs:complexType>
	</xs:element>
	<xs:element name="MediaType">
		<xs:annotation>
			<xs:appinfo>
				<jaxb:class name="MediaTyp"/>
			</xs:appinfo>
		</xs:annotation>
		<xs:complexType>
			<xs:attribute name="Text" type="xs:string" use="required"/>
		</xs:complexType>
	</xs:element>
</xs:schema>

The problem with Media and MediaType is overlapping class names ==> solved by renaming
the MediaType class to MediaTyp ('e' removed).
Generation goes fine now, but when unmarshalling an xml document (java sample below) I get
an error:

Exception in thread "main" javax.xml.bind.UnmarshalException: A Manager for test.MediaType
is not declared.
	at org.apache.ws.jaxme.impl.JMUnmarshallerImpl.unmarshal(JMUnmarshallerImpl.java:97)

	at Main.main(Main.java:21)

The java code that produces the error:

JAXBContext context = JAXBContext.newInstance("test"); // test was the package name I used
to generate classes to
		
Unmarshaller um = context.createUnmarshaller();
Config conf = (Config)um.unmarshal(new File("sample.xml"));

I don't where exactly the error comes from or how to resolve it except of renaming the xsd
elements (without the jaxb-tags), but this isn't a suitable solution.
