JAXB2 marshaller throws Validation Exception

Question

Hello All.. I am trying to marshall a JAXB Object using JAXB2 marshaller and validate it against an xsd.
During this process of validation, the parser when reads the xsd fails with the parse error. The schema xsd is a working xsd from a webservice provider. The validation is fine when it is done on XML Spy and SOAP UI. But when this xerces xmlschema validator comes to picture its even not able to parse the XSD for validating against it.
Here is the head of the xsd..
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
     xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
     xmlns:http="http://schemas.xmlsoap.org/wsdl/http/"
     xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/"
     xmlns:tns="http://com.cyber.space./services"          
     targetNamespace="http://com.cyber.space./services"
     elementFormDefault="qualified"
and a huge schema followed.
Step.1: I used this xsd to generate JAXB classes.
Step2. Used jaxb2marshaller from spring.oxm,
<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
          <property name="contextPath" value="com.cyberspace.service"/>
          <b><property name="schema" value="classpath:pathtoXsd"/></b>
     </bean>
so in my application , i have reference to marshaller object.so can use like this.
request ( the jaxb request object populated with valid values as per the schema)
result - output -- outgoing xml.
marshaller.marshall(requsest, result);
Here comes the problem..The out going xml is like this..
<?xml version="1.0" encoding="UTF-8" ?>
<Request xmlns="http://com.cyber.space./services">
<RequestService>123</RequestService>
etec etc etc.. son on..
This xml when converted to soap message and sent over to webservice its accepted as valid request and response is back. But all it happens when i dont validate it against the schema that i have.
Look at the :
<b><property name="schema" value="classpath:pathtoXsd"/></b> set as a property to jaxb2 marshaller.
This makes sure that the xml generated out the jaxb object after marshall process is valid against the XSD schema. Here it fails for some reason.
If the dont ask the marshaller to validate( removing the schema property ), then the xml is fine able to proceed with next steps of sending the successfull VALID SOAP REQUEST and response is back. But if do a validation by setting the schema property with value as path to xsd.
The error is :
Caused by:<b> org.xml.sax.SAXParseException: cvc-datatype-valid.1.2.2: ' ' is not a valid value of list type 'null'.</b>

Is it a problem with namespace.? If i assume that the resulting xml out of the marshall process when validated against the XSD is failing for some missing data( business data), then the request itself would not be sent as soap requst.
But the problem is not that with data in the xml. its some thing going on with the strict validation the validator is doing.

Hello,
The ABAP code looks ok except the missing if error != null statement.
Please check the similar code for raising exception provided in the below blog:
/people/ravi.gupta4/blog/2010/02/04/automating-cancellation-of-a-failed-message-in-xi
Also, Can you check whether exception is raised using Dynamic config UDF and a call to abap mapping is made.
Check the other approach of raising an exception:
