I took Sun's DTD to validate JNLP 6.0 athttp://java.sun.com/dtd/JNLP-6.0.dtd

I then I tried validating one of my JNLP files. It seems to think you
are not supposed to nest <java inside <resources which Sun's example
says is kosher.
Presumably the problem is the DTD->XSD conversion process was flawed.
The XSD is baffling. It seems to show both <java inside <resources and
<resources inside <java.

I've uploaded this document, plus the appropriate <!DOCTYPE directive,
to my own server at <http://bast.lionsanctuary.net/~owen/jnlp> and
used
the W3C markup validator - which determined that the document is
invalid per the DTD. Here is its output:
Line 204, Column 16: character ">" invalid: only delimiter "-",
number, "ANY", "CDATA", "EMPTY", "O", "RCDATA" and parameter
separators allowed. ...
Line 629, Column 29: name start character invalid: only delimiter
"&", delimiter "|", delimiter ",", delimiter ")" and token
separators are allowed. ...
Line 31, Column 27: element "shortcut" undefined. <shortcut
online="true">
You have used the element named above in your document, but the
document type you are using does not define an element of that
name.
Line 39, Column 42: element "update" undefined. <update
check="always" policy="always" />
You have used the element named above in your document, but the
document type you are using does not define an element of that
name.
I believe the first two errors are related to parsing problems with
the
DTD - the XML document itself is not 204 lines long, and the error
message relates to the validity of a DTD, not to a document. The Sun
DTD
contains errors in the definitions of the 'update' and 'shortcut'
elements, and this should be reported to Sun as a bug:
<update> should be <!ELEMENT update EMPTY>
<shortcut> should be <!ELEMENT shortcut (desktop?, menu?)>
I uploaded a mutilated copy of the DTD alongside the document (which
is
what you see if you look at the document now) that contains fixes for
these bugs. This is sufficient to allow DTD-based validation to
complete:
<http://validator.w3.org/check?uri=http%3A%2F
