Validating an XML File

Hello Ranchers,

I was trying to validate an xml file with an schema. I have attached the class that does it and the xml file and the schema file. I am able to validate this xml file with the schema using stylus studio. But when i run this class i get and error saying

Cannot find the declaration of element 'note'.

I hae spent lots of time on this and am not able to figure out what i am doing wrong.

Thanks for your help.....

The XMl File is.....

And the schema is.....

Constructing your own file URIs by a simple concatenation is not reliable. That's why the java.io.File class has a toURI() method. Why not use that?

I have tried using the toURI method, but get the same message...

This is what i had changed in my coded.

Is there some other place where i could have gone wrong?

Thanks a Lot

Could be. What does this expression produce?Is that what you are supposed to use there?

Thanks very much....

The code does validate the xml that have only one schema file.

What should i add in order to validate an xml file whose schema is specified in multiple files? That is one main schema which imports multiple schema file?
The above coded works well if there is one schema file, and does not when the main scheman imports other schema files.

Please advice...

Thanks again
