Changing DocType

Question

Dear All,
I have an application that is trying to insert a JDOM document into an Oracle DB.
Prior to do this, I need to change the DTD from
file:///V:/EURAC/Central_services/ICT_5/KNE/Projects/eldit/Prototype/MakeEldit1/WEB-INF/res/dtds/textNEW.dtd
to
/text.dtd
I wrote a simple function:
private int setDTDBeforeInsert(org.jdom.Document doc, File fileout) {
DocType docType;
docType = new DocType("/text.dtd");
try {
doc.setDocType(docType);
XMLOutputter outputter = new XMLOutputter();
OutputStream fout = new FileOutputStream(fileout);
outputter.output(doc, fout);
return 0;
} catch (IOException e) {
System.err.println(e);
return -1;
the problem is that the document already have an associated DocType so I receive an excpetion and there is no way to change it and to insert into DB.
Do ypu have any idea how to do it or any suggestion?

Answer 1

It is my experience to avoid this situation by instead of changing the document type itself, changing the task to have a new document type with the desired settings.
If for some reason the earlier periods are re-consolidated, the new setting are applied as opposed to the old and this has caused problems for me in the past.
