Invalid XML generated

Question

I thought I was figuring this stuff out, but I guess not. I've generated an xml
instance using xmlBeans. When I check it with the validate() method, it comes
back 'true' or valid. But if I run the Xerces sample app, counter, against it,
I get the following errors:
java sax.Counter -v output.xml[Error] output.xml:2:14: Document is invalid: no grammar found.
[Error] output.xml:2:14: Document root element "ns1:Envelope", must match DOCTYP
E root "null".
output.xml: 280 ms (22 elems, 0 attrs, 0 spaces, 343 chars)
I've attached the xml file I generated using:
InputStream IS = envelope.newInputStream(xo);
FileOutputStream FOS = new FileOutputStream("output.xml");
byte[] transfer = new byte[2048];
int count = 0;
while ( ( count = IS.read(transfer)) != -1 )
FOS.write(transfer, 0, count);

Answer 1

For some reason when I use MapForce tool to generate my xslt mapping source, it is generating the following statement in the xsl file.
     <xsl:namespace-alias stylesheet-prefix="n" result-prefix="#default"/>
So at the root element of XML file, it is replacing the character n with '#default' for some reason, I don;t know the purpose of this.
As you suggested, I changed the name space, still I experienced same problem.
It is now resolved after removing the above xsl statement from the xsl file before creating/uploading the relevant zip file into archives folder.
It works fine now. Thanks for the clue.
