Unmarshaller error, please help

[javaxmlsoapdev]

I get following error.

00:44:51,343  DEBUG [http-8081-1] - SoapMessageDispatcher - Endpoint mapping [org.springframework.ws.server.endpoint.mapping.PayloadRootQNameEndpointMapping@c9537b] maps request to endpoint [com.ats.fts.webservice.SessionEndpoint@2870b7]

where schema looks as below.

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:cfts="http://abc.com/xyz/schemas" elementFormDefault="qualified"
        targetNamespace="http://abc.com/xyz/schemas">
    <xs:element name="ExternalRequest">
        <xs:complexType>
            <xs:all>
                <xs:element name="EFEReqeust" type="cfts:EFERequestType"/>                       
            </xs:all>
        </xs:complexType>
    </xs:element>
    <xs:complexType name="EFERequestType">
        <xs:sequence>
        	<xs:element name="UserName" type="xs:string"/>
            <xs:element name="Password" type="xs:string"/>
            <xs:element name="MessageId" type="xs:string"/> 
            <xs:element name="MessageTag" type="xs:string"/>
            <xs:element name="MessageText" type="xs:string"/>
        </xs:sequence>                                                                   
    </xs:complexType>
</xs:schema>

And I generated classes using xjc. here is how XML request string is being composed from client code.

private static final String MESSAGE = "<ExternalRequest xmlns=\"http://abc.com/xyz/schemas\"><EFEReqeust>"+ 
	  									  "<UserName>User</UserName>"+ 
										  "<Password>password</Password>"+
										  "<MessageId>1012</MessageId>"+ 
										  "<MessageTag>1234</MessageTag>"+ 
									      "<MessageText>13380</MessageText>"+ 
										"</EFEReqeust></ExternalRequest>";

Any idea what is wrong in here?

Thanks,

By the looks of it, everything looks good. How did you configure the Jaxb2Marshaller?

I think the problem occurs because your java project isn't being built properly. It seems that the package-info.java, generated by xjc, is not being included in the build process.
Are you using netbeans by any chance? If so, try using the "Build" command instead of running your main class directly.

you are the man. I was always deliberately ignoring package-info.java from my build. now can you explain why is this class required. Had I not generated classes using xjc but created manually, I wouldn't have this class. can you explain?

Thanks a lot,

package-info.java is the source file that contains annotations targeting the package. In your case, it contains @javax.xml.bind.annotation.XmlSchema(namespace = "http://abc.com/xyz/schemas") which binds the JAXB2 generated classes to the specified namespace.
