Hi all,

I will make things more clear - 

Can anybody point out the problem - 

I have a multiple root node schema. And I am validation my XML against
this schema using JDOM with XercesJ parser. Code sections as follows -

===========================================================
if(new Boolean(CommonsUtil.readProps(Globals.SERVICE_ID,
"xmlSchemaValidation")).booleanValue()){
log.debug("Started validating XML against defined schema");
builder.setValidation(true);
XMLParseErrorHandler errorHandler = new XMLParseErrorHandler(xml);
builder.setErrorHandler(errorHandler);
builder.setFeature("http://apache.org/xml/features/validation/schema", true);
builder.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",
CommonsUtil.readProps(Globals.SERVICE_ID, "xmlSchemaLocation"));

}else{
log.debug("XML Schema Validation switched off");
}
Document doc = builder.build(src);

===========================================================
The parser validates one XML with root node "Response" but gives the
following error while validating XML with root node "Request" -

Error: cvc-elt.1: Cannot find the declaration of element 'Request'. at
line 1, co
lumn 10 in entity null

I know that the error description suggests that there is no definition
for the tag "Request" in the schema. But I have cross checked the
schema and the XML with XMLSpy, no problem in that.


Here is the schema, though a long one -
