DOCTYPE not created

[bill turner]

I've searched the web and news groups. It seems others have had this
problem. Unfortunately, the solution seems to be exactly what I've
coded. If anybody can point out what is wrong, I'd truly appreciate
it. What I am trying to do is to write an xml file to a local disk
file. Everything else comes out just fine. However, the DOCTYPE node
is not created. I've tried a number of different things, including
specifying that I wanted a validating implementation, all to no avail.
Here is a snippet of the relative code:

<snippet>
DocumentBuilderFactory builderFactory
= DocumentBuilderFactory.newInstance();
builderFactory.setValidating(true);
DocumentBuilder builder = builderFactory.newDocumentBuilder();
DOMImplementation impl = builder.getDOMImplementation();
//DocumentType docType =impl.createDocumentType("trapbatch",
"","trapmonkey.dtd");
DocumentType docType = impl.createDocumentType("trapbatch",null,
"trapmonkey.dtd");

//doc = impl.createDocument("", "trapbatch", docType);
doc = impl.createDocument(null, "trapbatch", docType);

rootElement = doc.getDocumentElement();
doc.insertBefore(doc.createComment("a good rule of thumb is to use
child elements rather than attributes if the information feels like
data"), rootElement);
rootElement.appendChild(doc.createComment("enterpriseSpecfic Traps"));
rootElement.appendChild(doc.createComment("if repeat attribute = 0,
the the delayInMillis attribute is meaningless. The The delayInMillis
attribute is defaulted by the application in all other situations"));

for (int i = 0; i < this.size(); i++)
{
trap = this.get(i);

trapElement = doc.createElement("trap");
trapElement.setAttribute("repeat", trap.getRepeat());

trapElement.setAttribute("delayInMillis",trap.getDelayInMilliseconds());

rootElement.appendChild(trapElement);

Bill,

After all the nodes have been added, try this:

String doctype = "-//Bigwebsite//doctype" ;
String dtdname = "http://Bigwebsite/dtdname" ;

javax.xml.transform.Source source = new
javax.xml.transform.dom.DOMSource(doc) ;
Transformer transformer =
TransformerFactory.newInstance().newTransformer() ;
transformer.setOutputProperty(OutputKeys.ENCODING, "ISO-8859-1");
transformer.setOutputProperty(OutputKeys.DOCTYPE_PUBLIC,doctype);
transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,dtdname);

File file = new File("outfile.xml") ;
Result sr2 = new javax.xml.transform.stream.StreamResult(file);
transformer.transform(source, sr2) ;

=========================

}

TransformerFactory tFactory =
TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();

hi,

the problem comes from the serializer : the default transformer just
perform a copy ; in xslt, the public and system ids must be set
explicitely :

Transformer transformer = tFactory.newTransformer( myStylesheet );

myStylesheet must be a stylesheet that performs a copy AND indicates the
output format :

<xslutput
doctype-public = string
doctype-system = string
/>

an other solution is to use another serializer instead of xslt's

DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new
File(System.getProperty("user.dir") +
System.getProperty("file.separator") +
TrapBatch.TRAP_TEMPLATE_TEST_FILE));
transformer.transform(source, result);


</snippet>

Again, thanks for your help!

there is a more convenient way : JAXP provides a mean to set the public
and system id directly ; try something like this :

Transformer transformer = tFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, "trapmonkey.dtd");

Thanks! That last piece solved the problem (I didn't try your first
suggestion). I spent days researching this. What a relief! Thanks
again, Philippe!
