JNLP validation


R

Roedy Green

I took Sun's DTD to validate JNLP 6.0 at
http://java.sun.com/dtd/JNLP-6.0.dtd
and ran in through the DTD->XSD converter at
http://www.hitsw.com/xml_utilites/

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 wonder if anyone would be willing to look at the xsd to see if it is
broken and why.

There are three pieces:

1. the JNLP 6.0 validating XSD schema.

2. A sample JNLP 6.0 file.

3. a program to use the scheme to validate the JNLP.

In the meantime, I will look for some other conversion utility.

I took Sun's DTD to validate JNLP 6.0  athttp://java.sun.com/dtd/JNLP-6.0.dtd
and ran in through the DTD->XSD converter athttp://www.hitsw.com/xml_utilites/

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

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 wonder if anyone would be willing to look at the xsd to see if it is
broken and why.

There are three pieces:

1. the JNLP 6.0 validating XSD schema.

2. A sample JNLP 6.0 file.

3. a program to use the scheme to validate the JNLP.

In the meantime, I will look for some other conversion utility.

Sure, I'll have a look. However, I'm curious - why are you converting
the DTD file, which is Sun's official definition of the JNLP schema,
to an XSD schema? It's possible to validate documents against DTD
schemas just fine, using most tools...

1. xsd is easier to understand.

2. I don't know how to use a DTD to validate. I do know how to use an
XSD.

3. I thought it would a trivial problem to solve. It is bad enough
asking for help without giving up on the project entirely. I wanted
this for to illustrate the use of XSD at
http://mindprod.com/jgloss/xsd.html

4. I want to know a bit more about XSD.

I took Sun's DTD to validate JNLP 6.0 athttp://java.sun.com/dtd/JNLP-6.0.dtd
and ran in through the DTD->XSD converter athttp://www.hitsw.com/xml_utilites/

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:/
%2Fbast.lionsanctuary.net%2F%7Eowen%2Fjnlp&charset=%28detect
+automatically%29&doctype=Inline&group=0>

More to come...

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.

Success. See http://mindprod.com/jgloss/jnlp.html
for all the pieces including DTDs, XSDs, and program for JNLP 1.0, 5.0
and 6.0.

I used Stylus studio to generate the XSD instead of the online
service, and made some minor tweaks.

With this framework the XSDs could be refined to catch more errors.

I took Sun's DTD to validate JNLP 6.0 at http://java.sun.com/dtd/JNLP-6.0.dtd
and ran in through the DTD->XSD converter at http://www.hitsw.com/xml_utilites/

Just before 24th July 2007, you started
a thread titled "JNLP xsd schema".

On 24th July, 2007, Piotr Kobzda pointed
out that the 6.0 JNLP DTD was invalid.
<http://coding.derkeiler.com/Archive/Java/comp.lang.java.programmer/
2007-07/msg02115.html>

I raised a bug report against the 6.0 JNLP DTD.
<http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6656846>

This bug was addressed, and Andy Herrick
assured me that the DTD in the spec. had
been updated (I have not checked that)
and that he had asked the web folks to
update the online version.

Your experience suggests that the online
version is still invalid.

Conclusion. GIGO.

No garbage in. I have that documented on my website, (you even get a
an acknowledgement) and I corrected the DTD before converting to XSD.

Good.

..I have that documented on my website, ..

Unforunately my bandwidth is very limited
at the moment and I have to make some drastic*
decisions about what I can download.

(* Many of the extensive MindProd pages time
out before completely downloading. That is
probably more a comment on my OS component,
and perhaps I should look into a browser that
lets me *set* the timeout.)

(grins) Thanks. But I hope you mentioned
Piotr K. *more* prominently. Most of what I
(think I) know about validation, came directly
from him.
..and I corrected the DTD before converting to XSD.

Excellent work.

Yes, I did. And I post the corrected DTD.

I get spoiled by either local viewing or viewing via high speed
internet from server only just a short ferry ride away.

I did not realise people were having trouble with timeouts. I should
have a look into splitting up the longest pages.

If you do a lot of viewing on my site, you could use The Replicator to
maintain a local mirror copy for you.
