i am developing xml business component which validates xml according to schema/dtd.
Here is my code which does validation.
/**
* create a Stream source for all schemas
*
* @param pSchema
* @return StreamSource[]
*/
public StreamSource[] getStreamSource(
String... pSchema) {
StreamSource[] lstStreamSource = new StreamSource[pSchema.length];
for (int i = 0; i < pSchema.length; i++) {
StreamSource lStreamSource = new StreamSource(pSchema[i]);
lstStreamSource[i] = lStreamSource;
}
return lstStreamSource;
}
/**
* Validating xml
doc with their schema
*
* @param pFileXmlOne
* @param pFileXmlTwo
* @param pValidate
* @param pSchemaNameOne
* @param pSchemaTwo
* @return boolean
*/
public boolean performValidation(String pFileXmlOne, String... pSchemaNames)
throws Exception {
logger.log(Level.INFO, "in performValidation");
SchemaFactory factory = SchemaFactory
.newInstance("
http://www.w3.org/2001/XMLSchema";);
Source[] lStreamSources = null;
Schema schema = null;
Validator lValidator = null;
Source lSource = new StreamSource(pFileXmlOne);
// split schema string by delimiter
lStreamSources = getStreamSource(pSchemaNames);
logger.log(Level.INFO, myClassName + "total no of schemas"
+ lStreamSources.length);
try {
schema = factory.newSchema(lStreamSources);
} catch (SAXException e) {
// TODO Auto-generated catch block
logger.log(Level.INFO, myClassName
+ "sax exception in creating schema" + e.getMessage());
throw new SAXException(e.getMessage());
}
logger.log(Level.INFO, myClassName
+ " before creating validator object");
lValidator = schema.newValidator();
logger
.log(Level.INFO, myClassName
+ " after creating validator object");
try {
logger.log(Level.INFO, myClassName
+ " before performing validation");
lValidator.validate(lSource);
lValidator.setErrorHandler(new SimpleErrorHandler());
logger
.log(Level.INFO, myClassName
+ " after performing validation");
}
catch (SAXException e) {
// TODO Auto-generated catch block
logger.log(Level.INFO, myClassName + " sax exception"
+ e.getMessage());
throw new CAFException(e.getMessage());
} catch (IOException e) {
logger.log(Level.INFO, myClassName + " IOException"
+ e.getMessage());
throw new IOException(e.getMessage());
}
catch(Exception e)
{
throw new Exception("xml do not contain xsd,dtd|| xml is not following dtd or xsd");
}
return true;

}
i am able to validate when i pass xml and the schema used in the xml.
if xml satisfies schema then i return true.
else iam throwing exception concerned to violation.
It is working fine ,but my problem is suppose i pass xml and the schema that is not used in the xml.
At that situation it is still validating according to schema and i am throwing exception of violation
But i should get output as schema not found.
please give your inputs/ideas to resolve this issue.
Thanks in advance.
