XML Validation with javax.xml.validation

[MoreFeo]

Hi, I'm trying to create a Web Service that validates an XML against an xsd file.

I've seen an example (

http://java.sun.com/developer/technicalArticles/xml/validationxpath/)

that uses javax.xml.validation against an org.w3c.dom.Document to validate.

The problem is that the Web Service receives the XML as a String, and I'm having errors when creating the Document.

This is what I have:

import java.io.ByteArrayInputStream;
import java.io.InputStream;
import javax.xml.parsers.*;
import org.w3c.dom.Document;

...

public String validateXML(String stringXML)
{
   try
   {
      byte byteXML[] = stringXML.getBytes();
      InputStream isXML = new ByteArrayInputStream(byteXML);
      DocumentBuilder parserXML = DocumentBuilderFactory.newInstance().newDocumentBuilder();
      Document documentXML = parserXML.parse(isXML);

      ...
   }catch(Exception e){}
}

I get an error at line Document documentXML = parserXML.parse(isXML);

It gives
java.io.UTFDataFormatException: Invalid byte 2 of 2-byte UTF-8 sequence.

Any ideas why it is giving this error?

Thanks

Ok, I've got it.

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
            Document documentoXML = dbf.newDocumentBuilder().parse(new InputSource(new StringReader(stringXML)));

Much easier than I was doing.
